The Critique of Political Economy; chapter 1 notes

Summary of Critique of Political Economy Chapter 1 by Karl Marx
(Chapter 2 to follow in a future post.)
Written before Das Capital, the Critique of Political Economy covers much of the theoretical ground of the opening chapters of Capital but in more detail. Sometimes readers have difficulty with the theoretically dense and stylistically strange nature of Capital’s opening chapters. For those interested in thinking more about these opening chapters, especially the stuff about money, it may be helpful to read the Critique.

The one caveat that is important to note however is that in the Critique Marx had not yet made the distinction between exchange value and value. The development of this important theoretical distinction is one of the most important aspects of the opening chapter of Capital.

What follows is a summary of the Critique. It is no substitute for reading the book itself. I write it mostly for self-clarification as I think about a future video on Money. The stuff on money is mostly in chapter 2, but I thought I might as well type up notes on chapter 1 while I’m at it. The origin of money in the commodity form is in chapter 1 though.

Chapter 1- Commodities

As we know a commodity has a use-value and an exchange value. The use-value of a commodity falls outside of the realm of political economy except in that it is a bearer of exchange value. Why? The use-value does not bear the mark of the social relations of production. We can’t tell that an object is a commodity by examining its use-value. The use-value is limited by the particular properties of the commodity, and is not a universal quality that can be quantified or compared with other use values in any meaningful economic sense.

[Of course, most of the uses that commodities serve are needs created by capitalism. So when Marx says that the use-value does not bear the mark of the social relations of production we should read this in the narrow, specific sense that the use-value has no relation to the division of labor or socially necessary labor time represented by a commodity rather than in the broad sense of the observation that uses and needs are created/conditioned by capital.]

Exchange value appears at first sight as a quantitative relation. Commodities are equivalent to other commodities despite having different, incomparable uses. Despite different uses Marx tells us they “represent the same entity.” (I take it this is a kernel of what later becomes the concept of ‘intrinsic value’) When two commodities have equivalent exchange values this means that they have equivalent volumes of the same time of labor. Though what Marx goes on to talk about is the quality of this labor (that it is abstract, simple labor, etc) it should be pointed out that he does seem to operate under the assumption at this point that equivalent exchange values represent equivalent labor content, on an individual basis. Of course, with his fully-fledged theory of price and value, as worked out in the 3 volumes of Capital (and in his comments in chapter 2 of this book), this identity of value and price, on the level of individual commodities, does not hold. He makes similar statements about quantitative equivalence in the beginning of Capital. My instinct is to take this as an opening assumption, abstracting from the complexities of the later stages of the analysis. But Marx does not state that this equivalence is merely a simplification.

What kind of labor forms the value of commodities? It is abstract, general labor. It is also simple labor. Labor time is the inherent measure of labor.

Simple labor is a real abstraction. There is a real process which reduces all labors to a common denominator. Labor does not appear as different, isolated labors. Instead, under capitalism, labors appear as different arms of the same social organ. As in Capital, Marx says that this is not the place to discuss the actual processes of the reduction of complex labor to simple labor. But tells us that it is a constant process. This makes it a real abstraction.

He covers the concept of socially necessary labor time.

In capitalism private labor produces exchange value. This is how it becomes universal labor, or social labor. This universal labor time is represented in the general equivalent. Hence, universal abstract labor is the specific type of labor of a capitalist society, not all human societies.

Marx enters into a brief discussion of the way the social relations between men appear inverted as social relations between things. This is obviously a precursor to the concept of the ‘fetishism of commodities’ introduced in the end of chapter one of Capital vol. 1.

Labor is both abstract and concrete at the same time. It is both social labor and natural labor. Concrete labor makes use-values. Abstract labor makes exchange values.

Use-values stay the same while the social relations around them change. Hence the labor time it takes to make a use-value can change and thus the exchange value changes. (It seems a simple enough point, yet we see the confusions that have been made in the 20th century by physicalist misreadings of value theory which seem to posit that exchange-value is the same as physical quantities!) Scarcity and abundance effect the productivity of labor and therefore APPEAR to effect exchange value directly.

The exchange value of a commodity is not revealed by examining one use-value in isolation (say, in the nature of a supply and demand graph), but by examining the relation of all commodities to each other. Exchange value manifests itself in the endless series of equations through which commodities demonstrate themselves as being the equivalent of another commodity in value. The universal equivalent is the one commodity that all other commodities measure their exchange value in.

The commodity is not a use-value for the seller, only for the buyer (if only this was understood by marginalists…). The commodity is only an exchange value for the seller and a potential use-value for the buyer. But it must be a use-value to a buyer in order for its labor to be social. (Though this is a condition for social labor it is not a determinate of the value of a commodity.) Private labor is not directly social. It must be socially useful to be social.

Here’s a puzzle: The commodity must enter exchange as social labor but this universality is only a result of exchange! How can this be? The puzzle is solved via the universal equivalent. The universal equivalent has two uses. It has its own use (if it is gold then it can make rings, microprocessors and stuff…) and it has a universal use in that it is used to measure the value of all other commodities. This resolves the contradiction of the commodity, that the commodity has a particular use value but a universal exchange-value. All commodities express their exchange-value not in an endless series of equations, but in one equation, their equivalence with the universal equivalent, money. This is expression of equivalence exists ideally before the purchase has been made. This is why we have price tags. We guess the exchange value of a commodity against money. But this price has to be realized in exchange in order for the process to be complete. Though exchange value has this ideal aspect this does not mean that money is a symbol. Money and value are quite real.

The fetish character of the commodity form is even more striking in money where money appears to have its own autonomous power.

Exchange value, of course, predates capitalist social relations. It originates at the borders of societies where trade begins between societies, not within societies. At first these exchange values are random. But as soon as a part of production begins to be production for exchange and not for use then exchange values begin take on predictable forms. This leads to the development of money.

Bourgeois economy treats barter as a natural form of exchange and sees money as a mere expedient. (This is true for contemporary bourgeois economy as well as the classical political economy.) Money is seen as a material instrument, a tool for simplifying barter, rather than as a social relation. But Marx knows that money doesn’t just solve the difficulties of barter in a technical sense. These difficulties arise from the development of exchange value and from the appearance of social labor as universal labor.

Notes on the History of the Theory of Commodites (a section at the end of Chapter 1) I didn’t take the best notes on this section…

Adam Smith thinks that the Labor Theory of Value applies to pre-capitalist societies. He sees it as a theory of subjective equalizations of labor time. Smith tries to derive exchange value from the social division of labor. Ricardo focuses on the quantitative determination of value rather than the qualitative side which would allow him to see the specifically capitalist nature of the value form. He sees capitalist labor as the eternal form of value. Sismondi focuses on the specific social character of labor, he develops an idea of necessary labor time and a critique of large industrial capital.

Ricardo represents the final shape of classical political economy. He leaves us with some controversies.
1. Labor itself has exchange value yet different types of labor produce different amounts of exchange value. We get into a viscous circle by making exchange value the measure of exchange value… Marx will later solve this by distinguishing between labor and labor power. The capitalist buys labor power but labor is what produces value. Marx says we need a theory of wages to explain this.
2. Point two seems to be a reiteration of point one. Marx says we need a theory of capital to explain this.
3. Supply and demand cause exchange-value to deviate from exchange-value. Marx says we need a theory of competition to explain this. Later, in Capital, when he develops the difference between value and exchange-value, this becomes a little clearer.
4. How do non-commodities have exchange value? For this, Marx says, we need a theory of rent.

Law of Value 10: Price and Value

[This is video 10 in my ongoing Law of Value series. It's a controversial topic... so, let's see what folks think of my attempt...]

Here’s a yo-yo. Let’s say it took an hour to make, parts and everything. And here’s a bag of high-fructose jelly beans. Let’s say they took 20 minutes to make. What if they both sold for $5, despite having different labor contents? Wouldn’t this be a big problem for Marx’s value theory?

When people get their panties in a bunch about price/value it’s over this issue of price and value not being the same all the time.  Ack! Is this non-identity of value and price the end of Marx and the end of all radical politics?

I hope not. After all, the reason we have two concepts, value and price, is because they are not the same. It is the relation between them that counts. It is the relation between them that explains the inner mechanisms of capitalist production and exchange. If value and price were the same we would automatically know how much labor went into a commodity and what level of output we needed to meet societies demand. But if we already knew all of these things then there would be no need to have value or price or even a market for that matter. We could just plan everything on a computer.

But we don’t have a planned economy. How many yo-yos and jelly beans should society produce? How much of society’s labor time should go in to each? Nobody knows! And when the capitalist buys plastic and string and hires yo-yo makers she doesn’t know how much profit she’ll make.  And when we go to the store we can’t see how much work went into our yo-yos and jelly beans! These decisions all must happen through the fluctuation of price signals. These fluctuations reflect back upon production to discipline and apportion labor.

Discipline and Apportion

When we say that labor is ‘disciplined’ we mean that Joe Shmoe on the jellybean assembly line is pushed to work at the average level of productivity. On the shop floor he is pushed by the speed of the machine and his boss. But the machine and his boss are being pushed by competition in the market to lower the Socially Necessary Labor Time it takes to make jellybeans. (see my video ‘Socially Necessary Labor Time’)

When we say that labor is ‘apportioned’ we are talking about how many people work at the jelly bean factory and how many work at the yo-yo factory, and so on. In other words, we are talking about the division of labor.

The division of labor and the SNLT determine what is produced, how much is produced and what the values between these commodities are.

But the unique thing about capitalism is that these decisions about disciplining and apportioning labor only happen after the labor has been performed. Price signals are judgements on past labor which then influence future labor (see my video Production and Exchange). As the products of labor leave production, enter circulation and then become inputs into future production we have a continual feedback loop of information.

Production and Exchange

This feedback loop could be confusing unless we remember this important principle:

‘value cannot be created in exchange’

Once you understand this almost everything else falls into place. Value is created in production by human labor. It takes the form of commodities with definite values. Commodities enter the market place where they acquire prices. Sometimes these prices are above their values. Sometimes below. These signals act back upon production to discipline and apportion labor. Thus the enormous, complex division of labor in a capitalist society is coordinated through the value relations between the commodities.

Because value cannot be created in exchange this means that the exchange of commodities is a zero-sum game. If some commodities sell above values then others must sell below. There can be no aggregate increase in value merely through the process of commodities changing owners. To have new value there must be new labor.

Unlike neoclassical theory where prices arise merely from the collision of subjective motivations of individuals bartering, totally abstracting away from the production process, the Marxist theory of of value and price directly links these phenomenon to the need for society to reproduce itself through a capitalist division of labor.

Value, Price and Money

Yo-yo’s don’t walk around with “1 hour of labor” written all over them. We only know the social value of a Yo-Yo through its money price. This is what we mean when we say that price is the ‘form of appearance’ of value. It is the visible, tangible form that value takes in the world. We only see the relations between laborers through the exchange ratios of commodities. Money is the god of all commodities. It is the one commodity that all other commodities measure their value in. Thus price is a very special type of exchange value. Prices represent values in the abstract. They are measures of abstract labor (See my video on Abstract Labor).

Thus when the price of a jellybean rises above its value this means that the jellybean commands more money than its value, that it commands more abstract labor in exchange than it required in production.

If value can’t be created in exchange this means that the total amount of value produced is always equal to the total prices of these commodities. But individual values and prices can and must diverge in order for the price mechanism to discipline and apportion labor.

Demand and Supply

One of the main reasons that prices deviate from values is the constant fluctuations of demand and supply. As capital revolutionizes the productivity of labor, values change, output and prices change, and demand and supply fluctuate. If demand for jellybeans is higher than supply then the prices of jellybeans rise above their values, they command more abstract labor in exchange, and this triggers a reapportioning of labor to bring supply in line with demand.

In the case of a monopoly or oligopoly supply is kept artificially low so that prices rise and the monopolists get extra profit.

If the supply and demand of yo-yos, jellybeans and all other commodities magically balanced, then prices would equal values. (That is, if we are abstracting from prices of production.) But if this was the case we wouldn’t have much need for price. We’d automatically know how much labor input went into anything we demanded and we could just organize everything on a computer without a market.

Side Note on Marx’s Method

Sometimes people think that profit comes from unequal exchange. This can be true for individuals but not for society as a whole because value cannot be created in exchange. One person’s loss is another’s gain. In order for there to be an aggregate increase in society’s profit there must be exploitation of workers for surplus value. In order to not confuse the individual profits than can occur from unequal exchange with the surplus value generate from exploiting workers Marx often suggests that we imagine that values=prices. This allows us to more easily see the origin of surplus value.

This does not mean that Marx actually thinks that prices always equal value, or even that they gravitate toward that state over the long run. In fact he says just the opposite: that demand and supply rarely meet and that prices and values are rarely the same.

Marx’s argument about surplus value, and all of his other conclusions as well, are totally valid whether or not values equal price. Sometimes people think that by pointing to value-price divergences they have somehow undermined the theory of surplus value. This is an error.

Review:

Before we move on we should review the main points thus far: Value can’t be created in exchange, only moved around. Money is the measure of value. If a commodity sells above its value this is the same as saying that it commands more labor in exchange than the labor that went into it.

Component Parts of Value

I haven’t been to a yo-yo factory but I picture an assembly line of people wrapping string around yo-yos. There’s probably another room where plastic gets poured into molds. But this isn’t all of the labor that goes into a yo-yo. Before any of this labor can commence materials much be purchased: string, plastic, molds, paint. And all of those inputs come from past labor processes elsewhere in the world. Every labor process has new active labor, which Marx calls “living labor”, and inputs from past labor, which Marx calls “dead labor”.

Dead labor cannot create value. The cost of purchasing inputs like string and plastic is passed onto the output prices of yo-yos, but no new value comes from this labor because it is already done laboring!

Living labor creates the new value. The worker creates the value of their wage so that the capitalist makes back their investment. The worker also performs surplus labor for the capitalist. This is surplus value.

At the beginning of the day the capitalist lays out money for inputs and wages. This is her cost of production. If she wants to continue to make yo-yos tomorrow she will need to make back enough money to buy inputs and wages tomorrow. Thus prices are inherently tied to the need for the system to reproduce itself. She also needs an incentive to invest: this is profit. Thus prices are inherently tied to the need for the capital to exploit labor.

The capitalist doesn’t lay out anything for surplus value. This she acquires from the worker for free. That’s why it’s called exploitation. But the profit capitalists get from selling their commodities is not always equal to the surplus value they produce. If the price of yo-yos rise above their value then when they are sold the capitalist’s profit is higher than the surplus value contained in the product! Surplus value has been transferred in exchange.

I started by saying that price and value were not equal because they were different concepts. Now we can add that surplus value and profit are not always equal because they represent different concepts as well. Surplus value can only be created in production but it can be redistributed in exchange.

If a capitalist’s profit is higher than the surplus value they create in production we call this “super-profit”. As we discussed in the video on SNLT, super-profits are the prime motivating force of a capitalist economy. They drive innovation and attract investment. They are a necessary part of capitalist competition.

Prices of Production

Now if you really want to talk about surplus value being redistributed in exchange then you have to talk about Prices of Production.

It starts with a puzzle:

Let’s say jellybeans take just a tiny bit of living labor compared to all the dead labor that goes into the inputs. You basically buy a lot of sugar, corn syrup and die, and and then you hire someone to push some buttons in factory while machines turn that sugar into bean shaped sugar. But let’s say that yo-yos take a lot more labor in comparison. You buy some plastic and string and then you have to hire people to make plastic molds, paint the yo-yos, and then let’s not forget how long it takes to wind up a yo-yo…. So the two industries have different proportions of living to dead labor.

Since the yo-yo factory has a higher proportion of living labor we can assume (assuming equal rates of exploitation) that the yo-yo factory must produce more surplus value than the jellybean factory. More workers means more value means more surplus value. We’d expect the yo-yo factory to be more profitable.

But there’s also this phenomenon called Average Profits.This is where the puzzle comes in. If capital is free to invest in any industry, free to move in search of the highest profits, this causes a tendency for profit rates to equalize. Jellybean makers start to invest in the yo-yo industry, cutting into their profit margins. Capital flows from one industry to the other. Supply and demand change. Prices change. Eventually, assuming the free flow of capital, jellybean makers and yo-yo makers enjoy the same rate of profit.

Now you see the puzzle. One industry produces more surplus value than the other, but they have the same rate of profit. HOW CAN THIS BE?

If we remember that value cannot be created in exchange, and that surplus value cannot be created in exchange, then we can easily solve the puzzle. First we note the following two principles:

1. Total prices equal total values.
2. Total surplus value equals total profit.

And the answer to our riddle is this: Surplus value is redistributed between capitalists to form an average rate of profit. That should seem simple enough since we’ve already discussed the redistribution of value in exchange.

How do capitalist’s redistribute surplus value? Do they send it to each other in the mail? No. Prices do this work of redistribution. The prices for some commodities fall, others rise, and thus capitalists gain and lose surplus value in exchange in a way that equalizes profit rates. In this way surplus value becomes less of the property of the individual capitalist and more the property of the capitalist class as whole, uniting the class in their common interest in the exploitation of labor.  These new prices, the prices which redistribute surplus value to form an average rate of profit, Marx calls “Prices of Production”.

Prices of production systematically deviate from values yet they are directly related to values. The total level of surplus value created determines the amount of value that can be redistributed to form these new prices of production. In addition, the tendency towards an average rate of profit is merely a tendency. Just as supply and demand fluctuate, never balancing, so do profit rates.

Another note on method.

So we see several different factors to keep in mind when discussing price.

If there is no equalization of profit rates and demand and supply are in balance then we can say that price=value.

If we assume a perfect equalization of profit rates and supply and demand are in balance then we can say that price=prices of production.

If we then let supply and demand fluctuate around these prices of production we get market prices.

Sometimes Marx just talks about value, sometime he talks about prices of production, and sometimes he talks about market price. These are three different levels of abstraction. Many mistakes have been make by people not paying attention to what level of abstraction is currently being discussed. Bohm-Bawerk, for instance, complained that in one place Marx said that value=price but in another place said that prices of production=price. He thought Marx was contradicting himself. But had Bohm-Bawerk been interested in actually reading Max a little more closely he might have realized that Marx’s analysis takes place on many levels of abstraction and that we must keep these levels in mind at all times if we want to understand what is going on.

We should also keep in mind that Marx’s central conclusions about exploitation, crisis and all of the other antagonisms of a capitalist society still hold whether we are talking about value, price of production or market price. Regardless of the level of abstraction, value cannot be created in exchange, and surplus value can only come from the exploitation of the working class.

Conclusion

We can only conclude that Marx gives a a quite robust and practical explanation of the way that commodity exchange regulates the reproduction of a capitalist division of labor and class relations. There is definitely a lot more to say on the topic, and a number of controversies to examine. On my WordPress blog you can find footnotes and references pointing you to more information and resources on this topic.

And now we can see how radically different Marx’s theory of price is from his Neoclassical critics. For neoclassical economics price is a reflection of equilibrium, of a state rest where all utilities are maximized. For Marx price formation is a ceaseless process of fluctuation that is part of a much larger process of value formation and distribution as capitalists compete to exploit workers better than their competitors, thus constantly revolutionizing the technological basis of society.

From Marx’s theory of price we can immediately move to a theory of capitalist crisis. Because the tendency toward an average profit rate redistributes value between industries there is no way to keep firms from investing more and more in machines and less and less in workers. In fact the race for super-profit compels capitalists to decrease socially necessary labor time by spending more on machines to make workers more efficient. This means while individual capitalists race to increase their own super-profit, that over time the average profit rate of the economy as a whole falls. The worker finds herself confronted with a greater and greater mass of machinery, while the capitalist class finds itself getting a lower and lower rate of return on larger and larger investments. The time is right for a crisis!

Footnotes: Actually this is more like a glossary of terms and topics:

Value: Marx’s terms have an elastic quality. In different places they stretch or constrict to contain more or less content.  This is because Marx understands things (and processes) only relationally. Things only have meaning in how they relate to other things. Value is a particularly elastic term because it sits at the very center of capitalist social relations. Sometimes when Marx says “value” he is talking about the exchange value of commodities, sometimes he is talking about the labor that goes into a commodity, sometimes he is talking about the form of social relations unique to a capitalist society. Understanding value theory requires that we are aware of what particular aspect of value is being referred to in a specific context. See Bertell Ollman’s “Dance of the Dialectic” for more on the elasticity of Marx’s terms.

Quality-Quantity: Value theory has both qualitative and quantitative dimensions. It’s a theory of social relations. In contrast to predecessors who treated categories like capital and labor only at the level of content, Marx was concerned with the form of these things took in a market society. In such a society they take the form of value relations and these involve certain laws, imply certain social relations, fetishism, etc…. These are all the qualitative aspects of value theory, in many ways the most crucial aspects of his theory to understand for formulating an understanding of the radical challenges of anti-capitalist politics.
But value theory also has a quantitative dimension, which comes to the foreground when we look at the value-price dimension. At times in the 20th century, due to the persistent myth that there was something internally inconsistent with the quantitative side of Marx’s value theory, Marxists have attempted to distance themselves from the quantitative aspects of value theory, instead developing approaches which attempted to side-step these quantitative aspects by focusing only on the qualitative aspects of the theory. This is no longer necessary, see my vid on TRansformation Problem.

Indirectly Social: Marx calls this unique way of organizing labor “indirectly social”. Rather than operating on some sort of plan where we decide how much labor should go into the production of various things our labor is distributed indirectly through the price signals of the market. We perform private labor. This labor is not social labor when we are performing it. It only becomes social after we finish working when the products of our labor meet in the market. Here in the market we find out if our labor has been socially useful and if it has been performed at the average level of efficiency. Isaac Rubin has a good discussion of Indirectly Social labor here.

Appropriation of Value: Bourgeois theory often confuses the appropriation of value with the creation of value in its idea of returns to factors of production. A bourgeois economist might argue that because the owner of land gets rent from their land that this means that the land has produced value. But in Marx’s system only human labor can produce value. The rent a landlord gets is an appropriation of value. The value is created elsewhere and the landlord appropriates it. (There’s a much more complex theory of rent, but that’s another topic.) Or we might hear that risk creates value. It could be that risky ventures require a greater potential reward to encourage risk. But there is a difference between making a big monetary reward on an investment (appropriating value) and actually creating value.

Money: Marx sees money as the embodiment of labor time in the abstract. He builds this theory directly from his theory of the commodity. Commodities have both a use-value and an exchange-value. The use-value is a specific dimension of the commodity particular to each object and their various uses. Exchange-value is a universal, abstract dimension of the commodity. It is the empty quantitative relations between a commodity and all other commodities. It is numbers, not qualities. This leads to the separation of use and exchange value. Use-value stays in the bodily form of the commodity while exchange-value separates itself from the commodity in the form of money. Money becomes the commodity that all other commodities measure themselves against. As such it is the universal measure of value and the universal measure of abstract labor. While Marx’s theory of money is robust and historical enough to allow for the evolution of non-commodity forms of money, at the abstract level he roots his analysis of Money in the money commodity (usually gold). Money gets its value from the fact that it is a product of labor. Money itself is a commodity with a use-value and an exchange value. But because its use as money becomes its purpose in measuring the value of other commodities this leads money to have some rather unique qualities. I will delve more deeply into the topic of money in a future video in this series. The best thing to read on Money is Marx’s “Critique of Political Economy“.

Equalities: Marx famously held three equalities to be true for the economy as a whole: 1. total value equals total price; 2. total surplus value equals total profit; 3. total value rate of profit equals total money rate of profit. This is discussed in vol. 3 of Marx’s Capital Part 2.

Organic Composition: the ratio of constant to variable capital is called the organic composition of capital and is drawn as c/v. The higher the organic composition in society as a whole, the lower the rate of profit. This is discussed in vol. 3 of Marx’s Capital, chapter 8.

Prices of Production: If capitalists receive an average rate of profit regardless of the ratio of constant to variable capital, how do prices of production still regulate the division of labor? Prices of Production still allocate labor because wages and surplus value are still involved in the prices of commodities. But, yes this allocation doesn’t happen as smoothly as it would in a world with no average rate of profit. In fact we already know that there is a systematic tendency in capitalism for capitalists to replace workers with machines. This increases the productivity of the remaining workers, allowing capitalists to produce below the SNLT and thus gain super-profits in exchange. Prices of production allow capitalists to continue to automate production without being punished for producing at a lower individual rate of profit. But if firms are replacing more and more workers with machines then less and less surplus value is being produced relative to the cost of all those machines. This leads to a Falling Rate of Profit in the economy as a whole. This is why in vol. 3 of Kapital Marx immediately moves from the discussion of Prices of Production to the theory of the Falling Rate of Profit. The tendency of the rate of profit to fall can lead to crisis, like the one we are in now. The rate of profit is only restored once enough capital value (ie the costs of production: workers, inputs) has been destroyed or devalued. See my video on the Falling Rate of Profit or any of my coverage of Kliman.

Input and Outputs prices: There is debate amongst Marxists as to the proper way to theorize input and output prices under Prices of Production. In short, many argue that input prices should not be valued at their original actual cost to the capitalist, but instead by the price it would cost to replace those inputs. This is called the ‘reproduction price’ of inputs. The logic behind this is that if prices of inputs rise I need to sell my product for more if I am going to repeat production tomorrow. This leads to a static equilibrium procedure in which input prices are retroactively revalued to meet output prices. But this process of holding input and output prices equal leads to the transformation problem and the various partial solutions to this problem. In response the Temporal Single System Interpretation (TSSI) holds that input prices should not be revalued to equal output prices, but that, instead there should be a temporal process in which output prices become the input prices of the next period, not the one that has already passed. Rather than valuing inputs at their ‘reproduction prices’ the TSSI folk value them at their ‘pre-production reproduction price’. That is the reproduction price of the input before it enters production. (See Kliman’s ‘Reclaiming Marx’s Capital’ for more on this.)

Transformation Problem: In short: Marx showed how value is redistributed in exchange to form prices of production. To do this he set up a simple numerical example where inputs purchased at their values are transformed into prices of production. But in the real world, his critics cried, inputs would be purchased at prices of production, not values! Since input prices and output prices must be the same in equilibrium theory (see above Inputs and Output prices) then there was some fancy math involved in figuring this all out. The upshot: total prices and total values don’t equal each other anymore. Furthermore value and production price were severed into two separate systems and it wasn’t clear what the relation was between them. The Temporal Single System (TSSI) response is to say that output prices of production are the input production prices of the next period, not the previous one. This eliminates the mathematical inconsistency in the transformation and also keeps values and prices of production as part of the same system, rather than two separate systems whose relation is only metaphysically related. The book to read on this topic is Andrew Kliman’s “Reclaiming Marx’s Capital; Refuting the Myth of Inconsistency”. 

In my own awkward way I made a video on the subject several years back.

Levels of Abstraction: Marxists treat the levels of abstraction in value theory differently. This is often because of the strange way in which the transformation problem developed. The traditional interpretation of the transformation problem severs value and price of production into two separate systems whose relation has to be arbitrarily imposed mathematically. Value is seen as somehow determining prices of production, and then market prices are seen as fluctuations around these prices of production. The Temporal Single System Interpretation (TSSI) takes a different stance on the issue. It seems values being created in exchange but being sold at market prices. These market prices form the inputs into production and the outputs. Prices of production are tendential prices that market prices gravitate toward. Critics claim that the TSSI has erased important theoretical distinctions between value and price and just explained prices through past prices. But the TSSI claims that it has cut through the bullshit metaphysics and mapped out the practical way in which inputs and outputs relate in a temporal, fluctuating economy. Central to the TSSI’s understanding of these levels of abstraction is Marx’s statement that price is the form of appearance of value (or more specifically in chapter 3 of Vol 1 “Money as a measure of value, is the phenomenal form that must of necessity be assumed by that measure of value which is immanent in commodities, labour-time.”). Thus value cannot exist in some separate metaphysical system, whispering into the ears of prices. Instead if appears as price and is transformed in exchange through the ways described above.

NeoClassical Economics: There are plenty of things to read if you are looking for a good critique of the neoclassical orthodoxy. The reason there are so many things to read is that orthodox economics is a huge religion, all smoke and mirrors, with little relevance to the real world. Viewers who know too much to be watching my videos in the first place will notice that in this video I throw Pierro Sraffa’s face into some of the group shots of bourgeois economists. Sraffa is not a neoclassical economist and is actually responsible for a number of quite useful critiques of the neoclassical orthodoxy (See Steve Keen’s “Debunking Economics” for a good synopsis of the Sraffian critique”. So it is technically wrong for me to group Sraffa in this category. On the other hand the Sraffians still maintain that there is an internal inconsistency in Marx’s transformation procedure because they insist on modelling value and price through general equilibrium analysis. Many 20th century Marxists also have been influenced by the Sraffian critique of Marx. For a good critique of some of the problems with this approach see Alan Freeman’s great essay “The Psychopathology of Walrasian Marxism”. That Freeman paper appeared in an excellent, and prohibitively expensive, volume of essays, many of which contain good critiques of equilibrium economics. I also enjoy Mark Linder’s “Anti-Samuelson” as well as Simon Clarke’s “Marx, Marginalism and Sociology” which I’ve written about here.

Suggested Reading on Value and Price:

Kapital. vol. 3 Karl Marx. specifically chapter 10

Value, Price of Production and Market Price by Alan Freeman- a  very short paper that lays out the main issues quite well and succinctly

Frontiers of Political Economy by Guglielmo Carchedi is a pretty solid exposition of the value price relation from a TSSI perspective.

Marx’s Theory of Price and Its Modern Rivals by Nicholas Howard is a recently published book on the topic which takes an alternative position than the one I’ve put forward here (at least on a few points). Howard takes a different view of input prices and the transformation problem than the TSSI folk and the TSSI and ‘New Interpretation’ are the subject of critique in the book. The book also has a fairly thorough critique of neoclassical, Keynesian, and Sraffian price theories.

Essays in Marx’s Theory of Value by II Rubin, though much of the book is devoted to more qualitative aspects of value theory, does get into the issues of price of production and market price. Rubin’s approach still seems mired in an equilibrium framework to me, though I think the book is great on the whole.

Value-Price- a draft script

This is a draft of the script for my next video “Value and Price”. Any feedback is helpful. The footnotes have yet to be numerically linked to the main text.

Intro

There is a lot of confusion over Marx’s theory of value and price. Let’s take care of that. [Obviously I'm just skimming the surface here, but I suspect that what my audience wants is a broad concept of the main points.]

When people get their panties in a bunch about price/value it’s over this issue of price and value not being the same all the time. At noon today a hot dog that took 20 minutes to make might sell for the same price as a bowel of soup that took an hour to make. Ack! Is this non-identity of value and price the end of Marx and the end of all radical politics?

I hope not. The reason we have two concepts, value and price, is because they are not the same. It is the relation between them that explains the inner mechanisms of capitalist production and exchange. If value and price were the same we would automatically know how much labor went into a commodity and what level of output we needed to meet societies demand. But if we knew all of these things then there would be no need to have value or price or a market for that matter. We could just plan everything on a computer.

But we don’t have a planned economy. What division of labor and what level of productivity are necessary for the division of labor to reproduce itself each day? Nobody knows.  When capitalist hire workers and buy inputs they don’t know what sort of profit they will make. And when we go to the store we don’t know how much labor has gone into the things we buy. These decisions all must happen through the fluctuation of price signals. These fluctuations reflect back upon production to discipline and apportion labor.

Discipline and Apportion

When we say that labor is ‘disciplined’ we meant that individual workers must strive to work at the average level of productivity. This is Socially Necessary Labor Time (see my video ‘Socially Necessary Labor Time’). When we say that labor is ‘apportioned’ we are talking about the division of labor, that is, deciding how much labor should be apportioned to what tasks. The division of labor and the SNLT determine what is produced, how much is produced and what the values between these commodities are.

But the unique thing about capitalism is that these decisions about disciplining and apportioning labor only happen after the labor has been performed. Price signals are judgements on past labor which then influence future labor. As the products of labor leave production, enter circulation and then become inputs into future production we have a continual feedback loop of information.

Production and Exchange

This feedback loop could be confusing unless we remember this important principle:

‘value cannot be created in exchange’

Once you understand that almost everything else falls into place. Value is created in production by human labor. It takes the form of commodities with definite values that enter the market place where they acquire prices. Sometimes these prices are above their values. Sometimes below. These signals act back upon production to discipline and apportion labor. Thus the enormous, complex division of labor in a capitalist society is coordinated through the value relations between the commodities.

Because value cannot be created in exchange this means that the exchange of commodities is a zero-sum game. If some commodities sell above values then others must sell below. There can be no aggregate increase in value merely through the process of commodities changing owners. To have new value there must be new labor.

Unlike neoclassical theory where prices arise merely from the collision of subjective motivations of individuals bartering, totally abstracting away from the production process, the Marxist theory of of value and price directly links these phenomenon to the need for society to reproduce itself through a capitalist division of labor.

Value- Price

If value is created in production then the value of a commodity is the socially necessary labor time that goes into it. But we can’t see this labor time when we look at the commodity. All we see are the exchange values that occur when this commodity trades with other commodities. We can only see the social relations between producers through these exchange values. When the commodity exchanges for money then we see a special form of its exchange-value: price. Price is the form of appearance of value. It is the way we see value at work in the real world.

If value can’t be created in exchange this means that the total amount of value produced is always equal to the total prices of these commodities. But individual values and prices can and must diverge in order for the price mechanism to discipline and apportion labor.

Money

When we say that price is the ‘form of appearance’ of value we mean that the value of a commodity is not stamped on its side for the world to see. We only see the relations between laborers through the exchange ratios of commodities. Money is the god of all commodities. It is the one commodity that all other commodities measure their value in. As such money represents value in the abstract. It is a measure of abstract labor (See my video on Abstract Labor).

Thus when the price of a jellybean rises above its value this means that the jellybean, commands more money than its value, that it commands more abstract labor in exchange than it required in production.

Demand and Supply

One of the main reasons that prices deviate from values is the constant fluctuations of demand and supply. As capital revolutionizes the productivity of labor, values change, output and prices change, and demand and supply fluctuate. If demand for jellybeans is higher than demand then the prices of jellybeans rise above their values, they command more abstract labor in exchange, and this triggers a reapportioning of labor to bring supply in line with demand.

If supply and demand were in balance then price would equal value. This is why it is meaningless to try to form a theory of price just by relying on demand and supply. If demand and supply were to actually balance for all commodities we would need some external factor to explain the exchange ratios between commodities. For this reason Marx often abstracts away from demand and supply imbalances when making his analysis of value.

Side Note on Marx’s Method

In fact Marx often asks us to assume, for the purpose of illustration, that value=price. This is not because he thinks that, on the average, or in the long run, value always equals price. It’s because the divergence of value from price has no bearing on any of his main conclusions about the qualitative aspects of value: that the origin of profit is the exploitation of labor, that capitalism is unstable and prone to crisis, etc. By isolating the fluctuations of price and value he can put our attention on the class relation between capital and labor in the workplace, instead of letting us get distracted by the distribution of value through market fluctuations.

Review:

Before we move on we should review the main points thus far: Value can’t be created in exchange, only moved around. Money is the measure of value. If a commodity sells above its value this is the same as saying that it commands more labor in exchange than the labor that went into it.

3 components of value

The value of a commodity is divided into 3 components:
constant capital (c)- is the value of the past labor that went into the production of any inputs.
The other two components of value are new value created by the worker.
variable capital (v)- is the wage paid to the worker
surplus value (s)- is the surplus labor the worker performs for the capitalist above the value of their wage.

The line between V and S is the site of class struggle as capitalists try to get as much surplus labor out of workers at a given wage. That’s why it’s called ‘variable capital’. The value of non-labor inputs are called constant because they can’t create any more value once they are bought. They pass their value directly into the value of the final commodity.

C+V represent the cost of production to the capitalist. Marx calls this the ‘cost-price’. Capitalists must at least recoup the value of their cost-price if they are to continue production each period. If they didn’t at least recoup their cost price they would not have money to pay workers or buy inputs.

But capitalists also must have an incentive to invest. They also require profit. But the profit they get from selling their commodities is not always equal to the surplus value they produce. Previously we said that value is created in production but that the seller can gain more or less value depending on the fluctuation of price. Now we can also say that surplus value is created in production but the capitalist can gain more or less profit than depending on the price of the commodity. If a capitalist’s profit is higher than the surplus value they create in production we call this “super-profit”. As we discussed in the video on SNLT, super-profits are the prime motivating force of a capitalist economy. They drive innovation and attract investment. The deviation of individual capitalists’ profit and surplus value is thus a necessary part of capitalist competition. However the total amount of surplus value produced is always equal to the total amount of profit received. As with price and value, surplus value can only be created in production even though it is redistributed in exchange.

Prices of Production

The most notable case of surplus value being redistributed in exchange is Marx’s theory of Prices of Production. Before explaining that we first have to take a brief detour to talk about average profit rates. If capital is free to invest in any industry, free to move in search of the highest profits, this causes a tendency for profit rates to equalize. As money flows into a high-profit sector, the supply of these commodities rise and their prices fall. Those high-profits start to erode. The opposite happens with low-profit sectors. Of course this doesn’t mean that all sectors of the economy always have the same average profit rate. This is only a tendency, one hindered by barriers to entry, monopoly, etc.

If surplus value can only be created by human labor we would expect the highest profits to come from capitalists who hire the highest ratio of workers to machines. We would expect the lowest profits from capitalists who spend lots of money on machines and very little on workers. (This is the concept of the ‘organic composition of capital’: the higher the ratio of machines over workers the higher the organic composition of capital.) If capitalist A spends $75 on wages and only $25 on constant capital we would expect her to make more profit that Capitalist B who spends $25 on wages and $75 on constant capital. The more workers relative to machines the more surplus value is produced per dollar invested. Both capitalists invest $100 but one has a much higher profit rate than the other.

Assuming no barriers to the flow of capital we should see a tendency for profit rates to equalize, for capitalists to make the same return on investment for every $100 invested. How can this happen? If we keep in mind the fact that value and surplus value can only be created in production but can be redistributed via prices and money then the solution is already in front of us. Surplus value is redistributed between capitalists to form an average rate of profit.

How do capitalist’s redistribute surplus value? Do they send it to each other in the mail? No. Prices do this work of redistribution. The prices for some commodities fall, others raise, and thus capitalists gain and lose surplus value in exchange in a way that equalizes profit rates. In this way surplus value becomes less of the property of the individual capitalist and more the property of the capitalist class as whole, uniting the class in their common interest in the exploitation of labor.  These new prices, the prices which redistribute surplus value to form an average rate of profit, Marx calls “Prices of Production”. They are formed like this:

c+v+p

where p is the total surplus value created by the working class divided evenly between capitalists, or the average profit.

Criticisms

There are some common critiques of Marx’s concept of value and price. There is room here only to sketch out a few and give some brief rejoinders.

1. Q: If price is just cost price (c+v) plus average profit what is the point of talking about value at all? Why not just have a theory of price that says prices are the cost of production plus an average mark-up?

A: Such a strategy would not explain the relation of price to the disciplining and apportioning of labor by capital, the social relations which are coordinated by the price system. After all, cost-price represents a definite quantity of current and past labor. And the average profit is completely dependent on the amount of surplus labor extracted by the working class.
If we eliminate value as a category then we have no way of explaining money. Money, as the commodity which all other commodities measure their value in, is the embodiment of labor in the abstract. Without this real abstraction we have no way of comparing the relative worth of one commodity from the next. This is why neoclassical theory doesn’t really have a theory of money, but rather bases its system upon the notion of barter. Marx, by contrast, shows how the intrinsic value of the commodity can only find its expression in the money prices.

2, Q: If value rarely ever equals price, what is the point of value analysis? How can you prove that they aren’t two sets of numbers, labor times and prices, coexisting with no relation?

A: Attempts to prove or disprove Marx’s theory of value by finding instances of price-value divergence or identity will always fail. This is because the theory only makes sense if individual values and prices deviate. Value is a process, always in motion, and always in fluctuation. By analyzing value we can understand the violent social contradictions that create this dynamism and fluctuation.
Some Marxists like to think of values like long-run equilibrium prices. If demand and supply were in balance, technology didn’t change, and there was no equalization of the profit rate then yes, values would be long-run equilibrium prices. But these conditions never occur and so I don’t know how useful this concept is.

3. Q: The transformation problem
A: There is a long standing claim that Marx’s concept of the Production Price is mathematically incoherent. This charge is called “The Transformation Problem”. But the TP is actually not a problem for Marx at all. It only arises when his value-price theory is forced into a bull-shit Walrasian General Equilibrium framework where input and output prices always equal each other and prices never change or fluctuate. As we’ve seen change and fluctuation are the whole point for Marx so this so-called problem is not really a problem at all. For more on this see my video “What Transformation Problem?”

Conclusion

We can only conclude that Marx gives a a quite robust and practical explanation of the way that commodity exchange regulates the reproduction of a capitalist division of labor and class relations. This in stark contrast with the neoclassical tradition which tells us nothing about the social relations of capitalism. Neoclassical economics’ main ideological purpose is to prove that markets lead to the optimum allocation of scarce resources. In order to meet this aim it must abstract away from capitalist productive relations, basing itself on a theory of barter. This means that money must be artificially injected into the model down the road since there is no role for value in the abstract. And when we get to Walrasian General Equilibrium price even loses its role. This is clearly not a science at all, but a sham set of elegant equations

Footnotes:

Value: Marx’s terms have an elastic quality. In different places they stretch or constrict to contain more or less content.  This is because Marx understands things (and processes) only relationally. Things only have meaning in how they relate to other things. Value is a particularly elastic term because it sits at the very center of capitalist social relations. Sometimes when Marx says “value” he is talking about the exchange value of commodities, sometimes he is talking about the labor that goes into a commodity, sometimes he is talking about the form of social relations unique to a capitalist society. Understanding value theory requires that we are aware of what particular aspect of value is being referred to in a specific context. See Bertell Ollman’s “Dance of the Dialectic” for more on the elasticity of Marx’s terms.

Quality-Quantity: Value theory has both qualitative and quantitative dimensions. It’s a theory of social relations. In contrast to predecessors who treated categories like capital and labor only at the level of content, Marx was concerned with the form of these things took in a market society. In such a society they take the form of value relations and these involve certain laws, imply certain social relations, fetishism, etc…. These are all the qualitative aspects of value theory, in many ways the most crucial aspects of his theory to understand for formulating an understanding of the radical challenges of anti-capitalist politics.
But value theory also has a quantitative dimension, which comes to the foreground when we look at the value-price dimension. At times in the 20th century, due to the persistent myth that there was something internally inconsistent with the quantitative side of Marx’s value theory, Marxists have attempted to distance themselves from the quantitative aspects of value theory, instead developing approaches which attempted to side-step these quantitative aspects by focussing only on the qualitative aspects of the theory. This is no longer necessary, see my vid on TRansformation Problem.

Indirectly Social: Marx calls this unique way of organizing labor “indirectly social”. Rather than operating on some sort of plan where we decide how much labor should go into the production of various things our labor is distributed indirectly through the price signals of the market. We perform private labor. This labor is not social labor when we are performing it. It only becomes social after we finish working when the products of our labor meet in the market. Here in the market we find out if our labor has been socially useful and if it has been performed at the average level of efficiency.

appropriation of value: Bourgeois theory often confuses the appropriation of value with the creation of value in its idea of returns to factors of production.

Money: Marx sees money as the embodiment of labor time in the abstract. He builds this theory directly from his theory of the commodity. Commodities have both a use-value and an exchange-value. The use-value is a specific dimension of the commodity particular to each object and their various uses. Exchange-value is a universal, abstract dimension of the commodity. It is the empty quantitative relations between a commodity and all other commodities. It is numbers, not qualities. This leads to the separation of use and exchange value. Use-value stays in the bodily form of the commodity while exchange-value separates itself from the commodity in the form of money. Money becomes the commodity that all other commodities measure themselves against. As such it is the universal measure of value and the universal measure of abstract labor.

Equalities: Marx famously held three equalities to be true for the economy as a whole: 1. total value equals total price; 2. total surplus value equals total profit; 3. total value rate of profit equals total money rate of profit

Prices of Production: If capitalists receive an average rate of profit regardless of the ratio of constant to variable capital, how do prices of production still regulate the division of labor? Prices of Production still allocate labor because wages and surplus value are still involved in the prices of commodities. But, yes this allocation doesn’t happen as smoothly as it would in a world with no average rate of profit. In fact we already know that there is a systematic tendency in capitalism for capitalists to replace workers with machines. This increases the productivity of the remaining workers, allowing capitalists to produce below the SNLT and thus gain super-profits in exchange. Prices of production allow capitalists to continue to automate production without being punished for producing at a lower individual rate of profit. But if firms are replacing more and more workers with machines then less and less surplus value is being produced relative to the cost of all those machines. This leads to a Falling Rate of Profit in the economy as a whole. This is why in vol. 3 of Kapital Marx immediately moves from the discussion of Prices of Production to the theory of the Falling Rate of Profit. The tendency of the rate of profit to fall can lead to crisis, like the one we are in now. The rate of profit is only restored once enough capital value (ie the costs of production: workers, inputs) has been destroyed or devalued. See my video on the Falling Rate of Profit or any of my coverage of Kliman.

Organic Composition: the ratio of constant to variable capital is called the organic composition of capital and is drawn as c/v. The higher the organic composition in society as a whole, the lower the rate of profit.

Value and Price Q&A

I have been looking forward to finally putting together a script for a video on Value and Price. As a preparation for that task I’ve written the following: an attempted summary of my understanding the topic. The text is peppered with paraphrases of questions that I have been asked by readers/viewers recently (and some I made up). I find these questions help focus the text and make the direction of inquiry relevant. There is a lot here. I wanted to get everything down so that I can then figure out how to distill it all into a video script. Please let me know what you think of the material, especially if there are unanswered questions or problematic formulations.

Q: Mudpies take labor to produce but they don’t have any value. Therefore everything Karl Marx wrote is a pile of shit. Why do you read that shit?

A: So the first thing we must do is to rid our mind of everything we’ve been told about Marx and the “labor theory of value” (a term Max never used.) The fundamental misconception that must be eliminated if we are to understand the value-price relation is the misconception that Marx thought that labor time and price were the same thing. Stumbling through the blogs and chat rooms one comes across this fallacy again and again. Marx did not think that every product of labor is magically imbued with a price tag equivalent of that labor. In fact, Marx was interested in explaining the opposite phenomenon, the phenomenon where labor sometimes produces nothing of value, sometimes produces a commodity that sells at its value, and sometimes produces a commodity that sells at more than its value. It is the “non-identity” of value and price that is of interest to Marx.

Often times in Capital Marx asks his readers to assume that price=value for this or that commodity so that he can more clearly discuss topics like exploitation and surplus value. Sometimes readers have misinterpreted this to mean that Marx thinks that value always equals price, or that Marx has some notion of long-run equilibrium price where value fluctuates around price. But this is not the case. In many places in Capital Marx states, as a matter of fact, that value and price rarely equal each other and that if they do it is only a manner of chance, an accident. These comments fly in the face of the common value=price misrepresentation of Marx.

Q: If there are so many exceptions where labor time deviates from price what is Marx’s point?
A: Such deviations are no exceptions. They are the phenomena to be explained. When we punch our time-card in the morning and go about our day’s work how do we know that the product of our labor will find a social use? How do we know that our labor will be efficient enough to compete with the workers in other firms? We don’t know these things for certain. We only find out after we have finished working, when the product of our labor enters the market to be compared with the products of everyone else’s labor.

Marx calls this unique way of organizing labor “indirectly social”. Rather than operating on some sort of plan where we decide how much labor should go into the production of various things our labor is distributed indirectly through the price signals of the market. We perform private labor. This labor is not social labor when we are performing it. It only becomes social after we finish working when the products of our labor meet in the market. Here in the market we find out if our labor has been socially useful and if it has been performed at the average level of efficiency. If our private labor has been efficient and put toward a useful end our firm/boss/capitalist is rewarded for our effort. If our private labor has not been put toward a useful end or if we haven’t worked efficiently enough our firm/boss/capitalist is punished by the market. These price signals then act to change the distribution of labor in society. People are hired and fired. The labor process is redesigned to make it more efficient. People are replaced by machines. etc.

Obviously this process couldn’t take place if there wasn’t some relation between the labor time that went into commodities and the prices of these commodities. But equally obvious is the fact that this labor time cannot exactly equal the price of commodities. If it did then there could be no price signals to punish or reward firms. Firms that are producing useless things or not producing efficiently are punished by the market. Better firms are be rewarded. So the simple picture of Marx’s value theory that we are sometimes given, that the labor that goes into production is exactly equal to the prices of commodities cannot be correct. There must be more to it if we are to understand the distinct way in which labor is distributed in a capitalist society.

Q: What do you mean by “social labor”? Aren’t there lots of types of individual labors that are not social at all? What about Robinson Crusoe’s labor?

A: If I make a turkey sandwich for myself and eat it this is privately labor only. My labor does not become social unless I am doing it for someone else. Whenever the products of our labor are exchanged we have done social labor. The fact that we are exchanging products points to an underlying distribution of relations of production. The fact that I need something someone else has produced (the fact that I have not produced it myself) means that there is a developed division of labor in society. The very act of exchange implies that there is a social organization of labor in which the private labors of different people are already socially dependent on one another. If there wasn’t this social aspect to our labor there would be no reason to exchange the products of out labor.

The distribution of labor and the products of labor in our society is based on a prior distribution of means of production in the hands of the capitalist class, depriving the rest of society of their own means of subsistence. Deprived of means of production, the working class must enter the market to purchase their subsistence and enter the market to sell their labor power to the capitalist class. Thus, the distribution of labor takes the form of wage-labor and the distribution of the products of labor take the form of commodity exchange. It is the quantitative value relations between commodities in the market that act back upon production, regulating the social division of labor. But this regulation only happens after the labor has happened: We work, the products of our labor enter the market, and then price signals act back upon production. This gives our investigation unique aspects that differentiate it from other societies based on a different distribution of means of production.

Q: If value and price are not always equal then what exactly is value? Sometimes it seems like “value” means labor time. Sometimes it seems like it means “price”. What is it?

A: Marx’s terms have an elastic quality. In different places they stretch or constrict to contain more or less content.  This is because Marx understands things (and processes) only relationally. Things only have meaning in how they relate to other things. Depending upon the context we may want to refer to more or less aspects of the inter-related parts of value relations. Value is a particularly elastic term because it sits at the very center of capitalist social relations. Sometimes when Marx says “value” he is talking about the exchange value of commodities, sometimes he is talking about the labor that goes into a commodity, sometimes he is talking about the form of social relations unique to a capitalist society. Understanding value theory requires that we are aware of what particular aspect of value is being referred to in a specific context.

Value theory has both qualitative and quantitative dimensions. It’s a theory of social relations that take on a quantitative form. In contrast to predecessors who treated categories like capital and labor only at the level of content, Marx was concerned with the form social relations take in a market society. In a market society they take the form of value relations between commodities and these involve certain laws that regulate and constrain the social relations. These are all the qualitative aspects of value theory, in many ways the most crucial aspects of his theory to understand for formulating an understanding of the radical challenges of anti-capitalist politics.
But value theory also has a quantitative dimension which comes to the foreground when we look at the value-price dimension. At times in the 20th century, due to the persistent myth that there was something internally inconsistent with the quantitative side of Marx’s value theory, Marxists have attempted to distance themselves from the quantitative aspects of value theory, instead developing approaches which attempted to side-step these quantitative aspects by focussing only on the qualitative aspects of the theory. This is no longer necessary: see my video on Transformation Problem.
When it comes to the quantitative aspects of value theory we are primarily concerned with the distribution of labor and the products of this labor throughout society.

Q: So I understand that price signals are the only means of coordinating the division of labor in a market society, but how exactly does this work? It seems there must be some relation between labor and price for this to happen. But there also seem to be lots of other factors that effect price like consumer demand, monopoly, etc. So how is this all understood by Marx?

A: Ok. Let’s get into it. First we should review the concept of Socially Necessary Labor Time, and then see how this relates to demand and supply. Following this Q&A form I’ll break the topics into questions.

Q: What is Socially Necessary Labor Time?

A: I deal with this in my Socially Necessary Labor Time (SNLT) video (Law of Value 6). There we saw that the social value of a commodity is not the amount of time it takes any individual to make a commodity but the average amount of time it takes society to make it. If I take way too long to make a pie this doesn’t mean I can sell it for more than the average pie. The average productivity of society imposes this social value over my individual value. If I produce at less than the socially necessary labor time it means my individual value is less than the social value. This allows me to make a super-profit when I sell at the social value. I haven’t created this super-profit. It was transferred to me in exchange, by people paying me the social value of my pies and not their individual value.

Firms don’t know whether they are producing at the SNLT until they meet in the market to compare their products. But this doesn’t mean that value is being created in the market. All of the value creation has already happened by the time the firms come to market. In fact, if we had some sort of omnipotent information on the productivity of each firm, we could predict that outcome of that market process before the products actually came to market. But we don’t have that information because we live in a capitalist society, so we must use the market to figure it out.

Q: Is SNLT just measuring the value of commodities within one industry? How do we determine value between industries?

A: The SNLT refers to the labor time required to produce a particular type of commodity. Obviously a basketball can have different colors and name brands but its value is still determined by a comparison with all of the other brands and colors of basketballs. This SNLT is the exchange value which basketballs have with money. Since all other commodities measure their SNLT in money as well we can use money prices to compare the SNLT of different types of commodities (basketballs, cars, etc.)

Q: What does it mean to say that value is transferred in exchange?

A: If I sell my product at exactly its value then I have exchanged, say, a beer worth $5 for $5. There is been no net gain or loss of value for myself or the buyer. In Marx’s terms I have “realized” the value of the beer. I have transformed it into its value equivalent. But let’s say I am an inefficient beer brewer and I would need to sell my beer at $8 to realize its value even though the firms producing at the SNLT sell their beer for $5. This would cause me to lose value in the market. I would either have to sell my beer at the SNLT of $5 and take a hit of $3 every time I sold a beer, or I would have to keep my beer at $8 and settle for selling less of them. The opposite happens if I produce under the SNLT. This allows me to make a super-profit in the market.

This idea of value being transferred in exchange is crucial to understanding the price-value relation. There are two different types of value being discussed: the individual value, or the amount of time a private producer spent making something, and the social value, or the SNLT, or the actual amount of money a commodity is sold for in the market. All producers sell at the social value but some lose value in this process while others gain value.

With this understanding we can also begin to conceptualize other price-value deviations. Anytime price is greater than individual value the seller is gaining value in exchange. Anytime price is lower than individual value the seller is losing value.

Q: You seem to be using labor time and value interchangeably here. You say the individual value is the labor time the private producer took to make a commodity but you say the social value is the amount of money the commodity sells at. And then you say that we can compare the two quantities to see the winners and losers. How do we compare hours and dollars?

A: This is a super important question. To answer it fully would require an in-depth discussion of Marx’s theory of money, but for now we can cover the basics. Marx sees money as the embodiment of labor time in the abstract. He builds this theory directly from his theory of the commodity. Commodities have both a use-value and an exchange-value. The use-value is a specific dimension of the commodity particular to each object and their various uses. Exchange-value is a universal, abstract dimension of the commodity. It is the empty quantitative relations between a commodity and all other commodities. It is numbers, not qualities. This leads to the separation of use and exchange value. Use-value stays in the bodily form of the commodity while exchange-value separates itself from the commodity in the form of money. Money becomes the commodity that all other commodities measure themselves against. As such it is the universal measure of value and the universal measure of abstract labor.

Q: OK, but how much labor does it measure? How do we know the relation between an hour of work and an amount of money?

A: Marx begins his discussion of money with the money commodity. The labor that goes into the production of gold becomes the standard against which all other labors are compared. So if an ounce of gold takes one hour of labor to make, then an ounce of gold=1 hour of abstract labor. If a commodity sells for 5 ounces of gold then its social value is 5 hours of abstract labor.

Q: Does this means that Marx’s theory of value rests on the concept of commodity money?

A: You will find a wide divergence of answers to this question amongst contemporary Marxists. I tend to agree with Marx’s own comments on the issue when he says that even though money originates as a commodity, it does not always have to be a commodity to perform its various functions of measure of value, standard of price, unit of account, means of payment, etc. It can be replaced by mere tokens of value like pieces of paper. However, there are times, especially in a crisis, where there arises a need to revert to the commodity form of money. In these cases we see the people flocking to forms of money which have some commodity basis.

Q: If money is not necessarily a commodity then how do we know how much labor time it represents?

A: I like the modern formulation of “Monetary Expression of Labor Time” or MELT (in case you need more jargon in your life). MELT is not a term used by Marx but I believe you can find instances where he uses a similar procedure. To answer your question MELT is found by taking the total amount of commodity prices in a given period and dividing them by the total number of hours worked. If $1000 of commodities have circulated in a year and 1000 hours of work went into them then 1 hour of labor equals 1 dollar.

(MELT is sometimes critiqued for different reasons, not all of which I have studied, but to anticipate some criticism I think it is worth noting that MELT does not imply specific direction of causality between the amount of money in the economy and the amount of labor performed. This is crucial because sometimes it is debated that the value of commodities determines the amount of money in circulation (Marx often argues this) and sometimes it is argued that the amount of money in circulation determines the level of prices. MELT doesn’t say anything about what determines what. It is merely a device for measuring the relation of money to labor time (see this paper on the topic.) It is used by some Marxists to perform calculations and form empirical observations about things like profit rates.)

Q: Your discussion of SNLT makes it sound like the various levels of productivity in an industry determine the social value of a commodity, but doesn’t consumer demand have a role in this price formation as well? What if there is a rise in demand for the products of an industry? Doesn’t this increase the price, the social value, of a product above the SNLT?

A: I get variations of this question all of the time. The short answer is, “Yes. The level of demand effects the social value of the commodity.” But there is more to it than the short answer.

First, there is the basic supply and demand question. When demand rises faster than supply can rise to meet this demand then prices rise. The speed at which supply can adjust to this new level of demand depends on the particular structure of the industry. In some situations it is easy to increase production to new levels without adding to the unit cost of a commodity. In other situations increasing supply involves new investments in plant and equipment, redesigning the labor process, even moving the location of production. These sorts of “inelastic” situations can cause supply to take a period of time to adjust to demand.

But eventually, given no other barriers to investment, supply can adjust to demand. When this happens supply and demand “cancel each other out” as Marx would say, and they cease to explain anything. Once again only SNLT can explain the exchange values between commodities.

When demand causes prices to rise this does not mean that demand is creating value. It is merely causing one industry to appropriate value in exchange. In order for, say, basketballs to sell above their value, other commodities would have to sell for under their value. This is because there is only a given amount of value in the economy at any time since only a specific amount of labor has been performed. This value can be moved around in response to changes in demand, etc. but it can’t be created just through the process of exchange. For more on this topic see my blog post “Value Can’t Be Created In Exchange”.

Q: Does this mean that Marx has an equilibrium theory of price where demand and supply eventually meet in the long run, or where there are long-run fluctuations around an average equilibrium point?

A: Many times you will see Marx’s value theory characterized in this way. This would give it a parallel with bourgeois general equilibrium theory. If we abstract away from changes in productivity then we can imagine a model where demand and supply balance and the price equals the value of a commodity. But if we consider that one of the most consistent themes in Marx is the constant revolution in the value of commodities due to the constant changes in the productivity of labor, then we have to drop this notion of equilibrium. Changes in productivity are driven forward by the capitalist’s quest for surplus value. And these changes constantly create disturbances in the relation of supply to demand as prices change. Rather than equilibrium, Marx’s theory of value and price points towards a constant state of disequilibrium. I have found Alan Freeman’s essay on this subject “An Invasive Metaphor: The Concept of Center of Gravity in Economics” to be illuminating.

Q: Is SNLT based on mean productivity, modal productivity or median productivity?

A: Modal. In math, a you find the mode of a set of numbers by observing which numbers occur most frequently. Within an industry the force of competition over SNLT moves most firms toward a modal level of productivity. But at a given moment there are still some firms which have yet to catch up to this modal level while there are still others that are racing forward to produce under the modal level.

When supply and demand are in balance SNLT is set by this modal level of productivity. But what if demand rises quickly? Then the modal firms cannot produce enough meet demand and the less efficient firms find that their supply becomes crucial to meeting demand. Rather than selling at a loss they find that they now set the SNLT. This is a different way to see the change in price due to a change in demand. Rather than demand just randomly changing prices it selects between different existing levels of productivity.

Q: I’m confused about the prices of clothing. I can buy two shirts of identical quality, obviously made under the same conditions of production, but with substantially different prices depending on the brand name. How is this possible within the labor theory of value.

A: If value can be appropriated in exchange, if value and price can and do diverge all the time, then it is easy to understand the role of other factors that influence price. Monopolies constrain the ability of price to reapportion labor. They artificially bolster up prices, keeping labor from flowing into those industries to bring down prices. The degree of monopoly determines the degree of price-value divergence…

Many companies can mark-up their products above values because they have a monopoly on a certain brand/image. They spend a lot of time, money and labor to create a brand and this gives them exclusive use of this brand. This monopoly over a brand gives them the ability to mark-up prices without fear of being under-cut by competition.

Since value can’t be created in exchange, any time one firm or industry gains super-profit in the market, someone else is losing value.

Q: Why is art work so expensive? What determines the value of art work? What about antiques? Is this a case for the usefulness of Marginal Utility theory?

A: Art and antiques are not freely reproducible commodities. They do not respond to the laws of supply and demand because their supply cannot be altered, their supply does not respond to price signals. There can be no reapportioning of labor time because they can only be produced once. Therefore the only thing that can determine their price is demand relative to their limited supply.

I can imagine this might sound like a concession to the primacy of other factors in ultimately determining price. On the contrary I think this actually brings out the important defining characteristics of Marx’s value theory and shows its superiority to marginalism.

Marginalism makes sense of the economy by abstracting away from production. People form consumer preferences based on a pre-existing world of commodities. These preferences are then considered all we need to know to understand price. This abstraction is much like the market for art or antiques where the commodity already exists as a static supply and all that matters in terms of prices formation is the level of demand for one commodity relative to another. I have criticized marginalism in several previous posts so I will not go into that here (see “simon clarke: Marx Marginalism and Sociology”, “Subject/Object”, “Script for a video that may never be produced“, etc.)

But the majority of the commodities produced are reproducible. Their production is sensitive to changes in price. This sensitivity triggers all of the above mentioned rules of value. We could just as easily posit the opposite situation where the demand for a commodity is static and supply determines the price. (hmmm… example?)

Regardless, when one buys expensive antiques the seller is not making a killing because value has been created in exchange. There has just been a transfer of value in exchange. This value only exists in the first place because it was created in production. The money that buys the antiques exists within a society in which money is the measure of abstract labor. In this way the logic of commodity production subsumes/engulfs all other forms of interchange.

Q: What is this term super-profit you keep using?

A: Marx never actually used the term and it has been used a few different ways by different Marxists. I use it to mean the additional profit a firm can make by selling a commodity above its value. This is different than surplus-value which is the profit the capitalist makes by exploiting their workers. I’ll assume that the concept of exploitation is already understood but a brief summary on the relevant points is probably useful:

Since value can’t be created in exchange the only way to make a profit is to pay workers less than the value they create. Now super-profit can be made by some by selling above value, but not all firms can do this. There is no way to increase the aggregate (overall) profit just by buying and selling. Without the profit proper that comes from exploiting workers there would be no reason for capitalists to invest in the first place. Assuming exploitation is successful, all capitalists make a profit. Some make a super-profit in addition to this.

Q: But a commodity’s price isn’t just the value created by labor. There are also costs of production like machinery and raw materials.

A: Yes Marx considers the total value of the commodity to consist of three parts: wages, costs of inputs, surplus value, or has he calls them “variable capital”, “constant capital” and “surplus value”. Inputs, or “constant capital” are called “constant” because their value is fixed at the time or purchase. The capitalist must transfer their value into the price of the finished product or else take a loss. Constant capital is, of course, the product of previous labor processes and its value is entirely the product of labor and nothing else.

“Variable capital”, or wages, is the called “variable” in order to emphasize the grey line between surplus value and variable capital. You are paid to work a 40 hour week. How much of that time are you producing value equivalent to the value of your wage and how much of that time are you producing surplus value (profit) for your boss? It is hard to say. It is a matter of class struggle. Capitalist constantly strive to increase the amount of surplus they can squeeze from the worker.

Q: What about a fully automated factory? This produced no value at all yet still has an exchange value. What gives?

A: First, an automated factory still has costs which they must pass on to the consumer. These are the costs of raw materials and machines. These are constant capital, just like in a normal factory. The real question is where the profit comes from in an automated factory. Nobody would invest in an automated factory if all they could do was receive the cost of their investment back. People invest for profit. In an automated factory there can be no surplus value production. All profit must be appropriated in exchange ã la super-profit.

We live in a highly mechanized society. Machines do many tasks that people used to do. When people did them they created value. When machines do them they create no value. In some examples this makes intuitive sense. Take the jobs that computers do calculating and duplicating information. Where we used to have to pay someone to set type and manually print a book now we can just duplicate it with a click of a button. No labor is involved. Hence this task no longer produces exchange value.

But take a camera factory that replaces all of its workers with robots  When humans worked there the capitalist added up the costs of production (wages+other inputs) and added the average expected rate of profit to this figure to form the price. When robots replace the humans the capitalist uses the same logic: add up costs of production and add the average expected rate of profit. This makes it seem like the presence or lack of human labor has no bearing on the formation of price.

Sometimes Marxists have responded to this problem by appealing to specifically unique characteristics of human labor. They say, “well robots may be able to turn screws and pull levers but they will never be able to do X” (where X is usually something like “think creatively” to “perceive beauty”.) I think such a defense is really problematic. Given the incredibly fast development of cybernetics I think it is risky to base ones theory of value on some arbitrarily chosen essence of human labor. (I was surprised to hear this argument made recently in a debate on the OPE listserve… I expected better from professional marxists.)

What actually differentiates human labor from robot labor is quite simple: humans have the ability to refuse work. This element of choice makes their labor a social matter. The inter-relations of human labor are social relations. In order to make humans work they must be dependent on the market for their survival. Their lives must be caught up in the consumption and production of commodities. This consuming and producing involves choices, the measuring of choices against each other, seeking personal advantage. The distribution of this labor and consuming is organized through the value relations between commodities.

Now if all production in society were full automated there would be no need for exchange value. Society would just be one big factory where production was carried out according to one big equation. (I should probably explain this more fully.)

Conversely, if robots ever developed enough intelligence to refuse work then their labor would become a social relation like human labor and would be value creating.

Q: What was that thing you were saying about an average rate of profit?

A: Aha! Now we get down to the really interesting stuff. You are an investor. You notice the the profit rate in Industry A is higher than the profit rate in Industry B. You decide to invest in Industry A, as do other people. As more money flows into Industry A this cuts into profits. Why? Because there are more competitors producing more goods. The increased supply doesn’t mean more demand, just lower rates of return. The opposite happens in Industry B. Investment flows out of the industry, supplies lower relative to demand. This brings prices above values and profit rates rise. This process causes a tendency toward an average profit rate.

But this causes a conundrum. If profit is total price minus the total cost of production then we would expect profit rates to be higher in industries with lots of workers and little constant capital costs than in industries with fewer workers and lots of constant capital costs (machines, etc.) Why? Because price is c+v+s (constant capital+variable capital+surplus value). And the rate of profit is s/(v+c+). This means that the lower c is, the higher the rate of profit, given v stays the same. Remember only workers can produce surplus value. So we’d think that having lots of workers is good for profit and replacing workers with machines would be bad for profit. When you replace workers with machines you have high costs of production but you don’t produce much value. This was scene as a paradox to adherents to the ‘labor theory of value’  (LTV) prior to Marx because it conflicts with the notion of an average profit rate. The LTV predicts higher profits for low ratios of machines to workers, but we also know there is a tendency for profit rates to become the same between industries regardless of the particular mix of workers to machines. It seems like profit is just an average return on investment and has nothing to do with labor being a unique source of value. It seems like machines can create value and surplus value just as well as workers. This leads Sraffian economists like Steven Keen to argue that the LTV is wrong and that commodities can produce value on their own.

But we can already anticipate Marx’s response to this notion based on what we already know about the transfer of value in exchange. For Marx the tendency toward an average rate of profit involves some firms losing surplus value in exchange and others gaining it so that firms with a low ratio of machines to workers (c/v) make the same rate of profit as the firms with a high ratio. Some sell at prices below values. Some sell at prices above values. These new prices Marx calls “prices of production”.

Q: So rather than the social value of a commodity involving SNLT now the social value just comes from adding the average rate of profit to the cost of production? Have we just replaced labor values altogether with a different theory?

A: This has been one historic criticism of Marx’s theory of price. Bohm-Bawerk accused Marx of literally contradicting himself on the issue. But there is no contradiction. We have seen that even the elementary theory of SNLT involves the deviation of value from price and the redistribution of profit in through exchange. The same happens with the theory of prices of production.

But what of the more general charge that there is no necessary role for labor as the source of value in the theory of prices of production? Even though there is a systematic deviation of prices from value this deviation is still related to labor times. What is the average rate of profit? It is the individual rates of profit of each industry averaged together. The average rate of profit is still determined by the total amount of surplus value produced by the working class as a whole. Thus the capitalist class literally exploits the working class as whole, not just as individuals.

Marx famously held three equalities to be true for the economy as a whole:

1. total value equals total price
2. total surplus value equals total profit
3. total value rate of profit equals total money rate of profit

Bohm-Bawerk responded that these were just tautologies that prove nothing. But they are not meant to prove anything. They merely frame the contours of what value is. Value is not a phenomenon where every commodity is going to magically appear with an exact measure of its labor time. The economy is much to complex for that. Rather, price, though formed wholly of the substance of value, is always a refracted measure of value, reflecting at any moment a number of different determinations.

Q: What if there are barriers to an average rate of profit? Then do commodities trade at their values?

A: Some people argue that the tendency to an average rate of profit is weak, constrained by lots of barriers to entry in industries, and that therefore commodities can be considered at trading, within fluctuations, at their values, not their prices of production. I think this is failed reasoning. It doesn’t matter that the tendency toward an average rate of profit is a weak tendency. It still must fit into a theoretical framework. We can’t just ignore it on empirical grounds. And even if profit rates weren’t equalized perfectly between industries this doesn’t mean that the profits of automated industries would automatically plummet while the profits of labor intensive firms would shoot up. In the practical world of investment and pricing capitalists expect an average return on their investment relative to their cost of production.

Q: But you said that the point of price was to allocate labor. If prices of production obscure the difference between humans and machines then how can labor be allocated in any sane way?

A: Prices of Production still allocate labor because wages and surplus value are still involved in the prices of commodities. But, yes this allocation doesn’t happen as smoothly as it would in a world with no average rate of profit. In fact we already know that there is a systematic tendency in capitalism for capitalists to replace workers with machines. This increases the productivity of the remaining workers, allowing capitalists to produce below the SNLT and thus gain super-profits in exchange. Prices of production allow capitalists to continue to automate production without being punished for producing at a lower individual rate of profit.

But if firms are replacing more and more workers with machines then less and less surplus value is being produced relative to the cost of all those machines. This leads to a Falling Rate of Profit in the economy as a whole. This is why in vol. 3 of Kapital Marx immediately moves from the discussion of Prices of Production to the theory of the Falling Rate of Profit. The tendency of the rate of profit to fall can lead to crisis, like the one we are in now. The rate of profit is only restored once enough capital value (ie the costs of production: workers, inputs) has been destroyed or devalued. See my video on the Falling Rate of Profit or any of my coverage of Kliman.

Q; I heard/read about this thing called the Transformation Problem that means that Marx’s theory of prices of production is all messed up.

A: See my video on the Transformation Problem and/or the Math Supplement to the video.

Q: I heard about this Okishio Theorem which invalidates Marx’s theory of the tendency of the rate of profit to fall.

A: Read this: Okishio, an obituary, by Andrew Kliman

In summarizing I’d like to say something very important. I hope that I have just shown that Marx’s theory of value is entirely coherent and logically sound. There are no unexplained phenomena. There are no nasty little exceptions that destabilize his argument. We are often told about the existence of all sorts of persistent myths about how this or that exception ruins his value theory. The vast majority of these accusations consist of trying to find examples of instances where prices deviate from individual values, whether that be in Mud Pies, automated factories, prices of production, or antiques. I hope that I have demonstrated that these are misguided attacks.

Just because Marx’s value theory is consistent, rigorous, and holds up to the basic requirements of logic doesn’t mean that it is correct. There is still an argument to be had over whether his theory actually explains the way the world actually works. Sometimes people confuse the two issues.

Steven Keen, for instance, argues that Marx is wrong to say that only labor can produce value. He does this by pointing to a supposed logical mistake in Marx’s description of exploitation. Marx says that the use value of labor-power is that it can produce value. Workers produce more value than they cost. But Machines can do the same thing, Keen argues. Marx ignored that machines can produce more value than they create. If Keen wants to argue for a theory of machines creating value that’s fine, but he shouldn’t do so by acting like he’s found some brilliant little hole in Marx’s logical argument. Keen acts as if he wants Marx, in the discussion of exploitation, to furnish some knock-down proof that machines can’t create value. But by this point in the argument Marx has already established that only labor can crate value. He is merely explaining the logical implications of such a theory. Elaborating on implications of a premise need not prove the premise. I’d almost be willing to say that they can’t prove the premise because you have to assume a premise to elaborate on its implications.

I feel like Keen’s argument is an obnoxious attempt to imitate what seems to be a trend: one makes up nonexistent problems regarding the logical structure of Marx’s argument and then uses these “discoveries” as material for riffing on one’s own theory of capitalism which has no relation to Marx at all. Keen would be better off just debating premises, and the basic questions of what a value theory is and what it means to express social productive relations through commodity exchange rather than to go on a fools errand to find some flaw in Marx’s own structure of argument.

I also want to stress that absolutely none of the qualitative aspects of value theory are effected negatively by the deviation of value from profit. I also do not believe that Marx’s method of deriving labor as the content of value is effected at all by the derivation of value from profit. In many ways, these qualitative and methodological questions are the important ones to have.

Price theory is not the goal of Marxist economics. The important take away is that Marx’s price theory does not contain some poison that destabilizes the rest of his understanding of capitalist social relations.

Supply and Demand- script for a video that may never be made

[I have been considering revising some of my proposed plans for the Law of Value series. Below is a script I wrote a while ago for Law of Value 11: Supply and Demand. I am considering skipping this video and moving directly to the video on price. The reason: this script is mostly a take-down of neoclassical supply and demand curves and doesn't say that much about the law of value. But I feel that there are still some good points in this script, worth sharing with readers.]

People sometimes think the labor theory of value is an alternative theory of price to the notion of supply and demand. This is not so. All of the classical economists who subscribed to a labor theory of value discussed supply and demand. Yet they did not think that supply and demand, by themselves, were enough to account for value and price. Most of us today have a vague notion of supply and demand (from some high school economics course we slept through) that relates to the neoclassical picture of supply and demand curves intersecting to select an equilibrium price. It certainly is a nice, simple image that elegantly conveys its ideas of balance, rationality and equilibrium, but when we look at a little closer we will see that this image doesn’t actually represent reality or help explain much of anything about reality. This video will both explain the relation of supply and demand to the Law of Value and deconstruct the neoclassical notion of supply and demand curves and equilibrium price.

What is the relation of the law of value to supply and demand?

It’s actually quite simple: There is a finite amount of labor in society. Yet the possibilities that we could apply this labor to are endless. Do we spend our labor curing cancer or building bombs? Writing string quartets or digging for oil? Social demand, the total demand of society, decides how much of each commodity is needed. The productivity of labor in each industry limits the total amount of supply we have to meet these demands. But there isn’t a committee that makes this decision. This decision is made through the price mechanism. Prices of commodities reflect a definite amount of labor that went into their creation. Commodities acquire their value in production prior to exchange. The more labor that goes into something the more value it has. When the supply of a toothbrushes exceeds demand for toothbrushes this means that too much labor has gone into making toothbrushes. Toothbrush prices are depressed below their value and this triggers a change in toothbrush production: labor must be withdrawn from toothbrush factories and applied elsewhere. If demand for toothbrushes is higher than the supply this will raise toothbrush prices above their values. This triggers an inflow of labor. Behind this fluctuation of supply and demand lies the actual value of a commodity. That value is the amount of labor time that went into making the commodity.

Even though the fluctuation of price moves above or below the value this doesn’t mean that value is erased. What happens is that the maker of toothbrushes receives more or less value in exchange then they produce. There is a value transfer in exchange. If there is an excess demand for toothbrushes this causes the social value of toothbrushes to rise above their individual value. The labor that went into making toothbrushes counts as more social labor than it actually represents. This causes a reapportioning of labor in society.

This fluctuation is essential to the law of value. Value only exists through the blind fluctuations of the market.

The traditional demand and supply curves have problems. Let’s examine them.

Neoclassical demand curves make the market seem rational, just, and equal. Consumers appear to be choosing to buy at a price that maximizes their personal utilities and producers selling at a price that maximizes their profits. This equilibrium price appears as a state of balance and harmony. All deviations away from equilibrium are just temporary, unimportant fluctuations. Attempts to interfere with this equilibrium, to disturb the status quo, will always make society worse off. This is the ideological backdrop to the neoclassical picture of supply, demand and price. (Simon Clarke argues that the development of marginal utility theory happened at a time of growing social movements that called on states to regulate labor conditions, markets, etc. Economists were looking for ways of measuring the effect of government actions on market processes. Hence the evolution of a theory of self-equilibrating markets. See Clarke “Marx, Marginalism and Sociology”)

The thing is, equilibrium prices are the most rational form of allocation for capitalists seeking to maximize profits. But they are not so for workers. We notice that workers and labor are left entirely out of the curves. For the neoclassicist these curves just represent utility, subjective desire. There is no role for the productive process or class. As we’ll see later, this lack of a theory of production makes the neoclassical concept of price circular and meaningless.

Equilibrium prices also don’t exist. The economy is never in equilibrium and never will be. It is constantly moving, changing, growing and contracting. Disequilibrium, often violent, is the norm. The regularity of economic crisis should be enough to prove that disequilibrium isn’t a freak accident of external interference in the market, but something internal to the the market itself.  (Booms are also an instance of disequilibrium. The economy doesn’t stay still in a boom. It expands.)
The Demand Curve- a joke

This is a neoclassical demand curve. It tells us that as prices rise people will buy less and less of something. As prices fall they will buy more. That seems logical enough. The curve is derived from a table of preference rankings based on the idea of marginal utility: The more you buy of something the less value you put on the next unit. So if you’ve already bought 10 bananas the 11th one has less value to you. The 12th even less, and the 13th even less than that.  Let’s say I’m willing to buy 10 bananas but not 11. The value I put on the 10th banana, the banana at the margin of my preference scale, is the price I will pay for bananas. This is what the demand curve shows, that the more bananas I buy the less value they have to me. This too seems to make sense at first… if we set aside the fact that people don’t ever buy bananas one at a time.

But what about capitalists? Workers are not the only people that buy things. Capitalists’ demand is a huge part of the economy. During the boom phase of an economy capitalists’ demand increases the more they buy. The more inputs they buy, the more profit they make, the more production expands, the more their demand for inputs grows. They do the opposite of what is predicted by marginal utility.

Let’s say the equilibrium price for a banana is 10 cents. What does 10 cents mean? Neoclassical economics has no answer to this question. It just says that 10 cents is the equilibrium price in which everyone’s utility is maximized. The price of health care is so high that millions of Americans can’t afford it. For neoclassical economics this is an equilibrium price. They say those of us without health care have maximized our utility because we value the money we didn’t spend over the value of health care. But most of us don’t have that money in the first place. Clearly this is a meaningless concept of equilibrium and price. When prices rise rich people continue to buy the same amount of stuff. Some even buy more because of the status associated with expensive things (fur coats, fancy cars). When prices rise poor people buy less.

So we see that the diminishing demand for bananas isn’t just a function of having a diminishing utility for bananas. It’s a function of how much money we have to spend. And this is a function of income- a concept that relates directly to production. The income of workers corresponds to a definite amount of work at a definite wage. The income of capitalists corresponds to a definite amount of value appropriated from the working class. And both of these relate back to labor. Without a theory of labor and the value it creates in a capitalist economy the idea of demand is meaningless.

Without this reference to labor the neoclassical theory of price becomes circular. Again, what does it mean to say that bananas are 10 cents? It means nothing at all unless we realize that the price of bananas reflects the relation of bananas to all other commodities. If bananas are 10 cents, apples are 12 cents, and oranges are 25 cents, then we can see the meaning of price. Price reflects quantitative relations between commodities. If the price of bananas rises to 10 dollars a banana people will buy apples and oranges instead. This will change the price of apples and oranges. But if the price of all fruit is rising this will effect the demand for bananas differently. We can only understand price and value in this relational way, as a relation of the value of one thing to another. Yet the demand curve can only be drawn by holding the prices of all other commodities as constant. If we are drawing a demand curve for bananas we must assume that prices are held constant for other replacement goods like apples and oranges. But this means that we must take for granted that which we are trying to explain. We must assume price in order to explain it. There is no way to escape from this circularity without referring to something outside of price. This something is labor.

….. when picking on neoclassical economics it can be hard to find a stopping point. But there’s one more thing about the demand curve that has to be mentioned.

Neoclassical economics draws the demand and supply curves as mirror images of one another in this way conflating the motives of consumers and capitalists.  This allows economists to claim that just as capitalists seek to sell at a price which maximizes their profits consumers buy at a price that maximizes their utility, giving them a “consumer surplus”. Yet unlike capitalist profit, which is a real objective magnitude measured in money, this consumer surplus can’t be found anywhere in the real world. It exists only in the minds of economists. A surplus of money is a clearly objective phenomenon. Psychological satisfaction is not an objective thing. It can’t be measured in any numerical amounts, and there clearly can be no such thing as a surplus of subjective satisfaction over an objective amount of money spent. That’s like having a surplus of love over bananas. Such logical mistakes abound in marginal utility, reducing its theories to circularity and meaninglessness.

Supply

Since the supply of a commodity is determined by the amount of labor that goes into making it and the productivity of that labor we’d think that labor would be at the center of the neoclassical conception of supply. Yet, somehow it is able to completely remove this from the analysis.

Here’s a neoclassical supply curve. It’s the opposite of the demand curve. It predicts that as prices per unit rise capitalists will produce more of a commodity thus making more profit. Yet as production increases the cost of production can also increase. Therefore at a certain point the returns on additional production start to shrink.

This all seems to make sense. But because the supply curve focuses on individual unit prices and not total price it misses out on something very important. The most important strategy for capitalists to increase profits is to increase the efficiency of production. This allows them to sell more commodities at a lower price, increasing profits by out-competing rivals. If we were to draw a curve based on this fact, supply would actually rise with shrinking prices, just like the demand curve! But of course neoclassical economics wants to abstract away from the way that changes in labor productivity alter the value of commodities.

Because of its obsession with equilibrium the supply curve also assumes equal productivity throughout an industry. But as we’ve seen capitalists are constantly competing to lower the socially necessary labor time. This means that they are constantly investing in new equipment to increase efficiency. Investments in long-term fixed capital like factories create all sorts of inequality between different firms in terms of the level of productivity. So rather than one level of productivity throughout an industry we have several.

We could think of this as a series of smaller supply curves. At the left of each curve is a price below which a firm can’t make a profit at all and will go of business. To the right is a supply which is beyond the firms capacity to produce, at which additional production will be too costly. Demand determines which one of these firms will set the market price. If demand equals supply then the average productivity, the socially necessary labor time will be the price. But if demand is above supply then the least efficient firm will set the price and the other firms will receive a super-profit. If demand is below supply then only the most efficient firm can make a profit. The others will be forced out of business.

Rather then demand creating price, demand is selecting from amongst pre-existing prices based on the productivity of labor. This is the actual way in which demand and supply interact.

Equilibrium: If it ever happened it would be meaningless

Neoclassical economics assumes that the intersection of demand and supply creates an equilibrium price. This equilibrium is so powerful that any deviation from it is unimportant. Yet, in reality, demand and supply never meet. There is always a constant shifting between the two. For the neoclassicist these fluctuations are fluctuations around a center of gravity called equilibrium. Equilibrium is the average and this is why the fluctuations are unimportant.  But what is ignored is that this “center of gravity” is constantly moving. As demand and supply fluctuate they change where the center is and this is why they never settle on equilibrium. Rather than tending toward equilibrium, the economy is in a constant state of disequilibrium as the interaction of supply and demand constantly change the productivity of labor.

If supply and demand ever did meet they would cancel each other out and be meaningless. If the economy was in a perfect state of equilibrium with supply and demand for all commodities in perfect balance this would tell us nothing about why some commodities are worth more than others. Fluctuations in supply and demand can tell us why the same commodity has a different price at different times, but supply and demand can not explain the relation of one equilibrium price to another.

What creates supply and demand?

By now that should be obvious. Supply is created by labor. Now, labor is not the only “factor of production”, yet it is the only one that we have control over as a society, and thus the one that can be the basis of social value. (This is why animals don’t create value. They may do work and create products but they don’t produce value because value is a social relation between people, not a measure of physical products. Animals don’t enter the market looking to buy commodities. Nor do robots- yet.) The sun, water and land are crucial for agricultural production. Yet these factors are pre-existing gifts of nature. If we are to try to exert control over them so that we can ration them differently through irrigation, improvements in fertility, or greenhouses, these improvements will require labor.

Demand is also created by labor. Demand is a certain amount of value in the market in the form of wages and profits looking to buy things. And those things we buy are also conditioned by the structure of production. Capitalists’ demand is given by what sort of inputs are needed for production. Workers’ demand are based on the level of productivity in society: what sort of commodities are available and at what cost. We can do better than the neoclassical idea of demand as some sort of magically independent force that shapes the direction of society. Demand itself is shaped by the structure of society.

Conclusion

If we were to take all of these problems with the neoclassical conception of demand and supply we could boil them all down to one thing: they try to explain demand and supply with utility instead of value. By relying on the subjective dimension neoclassical economics deprives itself of the ability to describe actually existing social relations and mires itself in endless circularity, always needing to assume prices in order to explain them. Because production is left out of the picture the motives of capitalists and workers are conflated, subsumed under the vague heading of ‘consumer choice’. Temporal motion and change are excluded from the picture giving capitalist social relations a timeless, universal character.

But neoclassical economics must do this in order to avoid discussing the organization of production in a capitalist society. It must paint the existing order of things as the natural result of people’s free choices and desires rather than of an unequal social order based on private ownership of the means of production and the exploitation of wage labor. In short, it must abandon the concept of value. This is what classifies it as ideology and renders it meaningless.

When we add labor back into the picture we get a very different picture of things. We see that behind both demand and supply there exists a labor process and that this labor process is a dynamic one, constantly in disequilibrium. We can still use the idea of demand and supply curves but they come out looking very different than the neoclassical curves.

further draft of subject-object

Perhaps it borders on narcissism to think that the world is interested in following the successive redrafting of the scripts to my videos. But I suppose there are worse things to clutter the internet with. I do always find feedback quite useful. This is the 2nd half of my Law of Value 8: Subject Object script, totally reworked. I posted the entire script last week but I decided that the second half, which deals with marx’s concept of subject/object inversion needed to be rewritten entirely.

My goals in this revision were:

1. Address the effect of demand on market prices and explain why we don’t need a subjective theory of value to explain this or why this is not a problem for marx’s theory of value.

2. Tie the point about “real abstraction” to the concept of subject/object inversion and fetishism.

3. re-order the flow of concepts to make things as succinct as possible and less academic sounding. This point still needs work.

Here it is:

Subject-Object, draft 4, second half:

In the Real World….

In the real world, outside of the fantasies of bourgeois economics, subjects and objects have no meaning apart from their relations to each other. There is no such thing as a subjective individual floating in a vacuum. We develop our subjectivity through our relation to the objective world we inhabit. And while the objective world can surely exist without subjects, it has no meaning for a social theory like economics except the meaning that people give it. Subjects and objects always exist in a relation, deriving their meaning from this relation.

This relation is not just one of coexistence. It is an active process of by which subjects engage with the objective world, transforming it. People work on nature. We chop trees and make houses. We build cars and dig up oil to power them. In so doing we transform the objective world and also transform ourselves. The manner in which groups of people work on and transform the world around us has changed through history. These different modes of relating to and transforming the world Marx calls “modes of production”. (brief mode of production chart with Feudalism, Slaveocracy, Capitalism, Communism, etc. and some picture depicting S/O relation?) (footnote on materialism)

This productive activity doesn’t just transform and create the objective world around us. it also creates our subjectivity. It determines what sort of things we value, how we go about getting the things we desire and how we relate to other people. Different modes of production produce drastically different types of societies with different value systems, different ways of relating to our desires, and different social relations between people.

Every mode of production is limited in terms of the social results it can achieve. The capitalist mode of production, for instance, though quite good at producing lots of stuff, is unable to solve basic social problems like poverty, exploitation, war, and economic crisis within the parameters of the capitalist mode of production. This is because capitalism has a very interesting quality as a mode of production, a quality Marx calls “subject/object inversion”. We will return to this quality in a moment.

Subjects, Objects and their Prices (image of commodity and person, both with price tags)

Objections to Marx’s theory of value often have to do with the way his theory of value relates to market prices. If value comes from the amount of labor that goes into producing things, then how do we explain the fact that a rise or fall in demand  changes market prices? The fact that demand influences price makes it seem like subjective decisions influence value as much as labor time.

The value-price relation is not an easy one to enclose in neat, tidy definitions. The more we look at it the more complex the network of social relations that go into the formation of prices. I will deal with the value-price topic in more detail in a future video (Law of Value 11: Price), but a few remarks are in order here. We’ve actually covered this ground briefly before in Law of Value 3 where we talked about the way private labor becomes social labor. (footnote on price)

Private labor is the amount of labor an individual worker devotes to the production of a commodity. The goal of the worker is for her private labor to become social labor, that is, that her commodity be sold in the market and thus be equated with all the other commodities in the market, making her labor part of the total social labor of society. But this isn’t so easy. Because production is only coordinated through the fluctuation of market signals, it is always uncertain whether commodities will be sold, and whether private labor will become social labor.

As we’ve seen in previous videos, in order for private labor to become social it must produce at the socially necessary labor time. SNLT is a way in which the social level of productivity acts back upon the private labor of the individual, disciplining the individual to work at the social average. Individuals or firms that can’t work at the SNLT go out of business, like when American auto-workers lose their jobs due to competition with plants in other countries. Their labor is then reallocated to other areas where they can be more profitable, or they don’t work at all. As many of us know, losing a job and having to find new work is a long, hard, painful process. But these discomforts don’t matter to the market. The market treats all labor like digits in a calculator, anonymous units to be moved around in the search of profit.
(long footnote on self-employment)

In addition to producing at the average level of productivity, there also must be a demand for the products of labor if private labor is to become social. If too much private labor goes into the production of elevator music than there is demand for elevator music then some of this music will remain unsold and some of this private labor will not become social. Producers will be forced to move their labor elsewhere. But rather than this being an example of demand creating value, it is an example of how changes in demand effect the distribution of social labor. This is part of the phenomenon Marx is explaining in his theory of value: the labor of society is coordinated through the fluctuations of prices, a phenomenon only possible because there is a relation between prices and labor time.

Furthermore, demand itself can only be understood if we abandon the concept of the isolated individual and see demand as part of a huge social process whereby capitalist production reproduces itself. The only type of demand that counts in the market is “effective demand”, that is demand backed up by money. Consumer demand comes from wages paid to workers. The products which consumers buy with this money are not just the random result of psychological preferences. In fact, most of our money goes to the purchase of very basic things we need in order to keep us alive as workers so that we can produce more value for capitalism each day: rent, food, clothes. (footnote on consumption) These are needs and desires dictated to us by capitalism, for the purpose of perpetuating capitalism, not the abstract psychological preferences of isolated individuals.

The bulk of the demand in society comes not from consumers but from capitalists. You and I buy toothbrushes and pay rent. Capitalists buy factories, assembly lines, natural resources, and private armies. This demand has nothing to do with the personal preferences of capitalists. (corporate greed footnote) It has to do with the technical requirements of production, the amount of inputs it takes to make a widget at the SNLT. Some people think that capitalists enter production only in order to meet the demands of consumers. This is a myth. The advertising industry is the best refutation of this myth. Capitalists produce in order to make a profit. Then they go looking for markets. Most of the time they have to create the market by convincing people there is a need for their product. But capitalist firms also sell to each other, totally bypassing the need to find consumer markets. (footnote on undercon)

This all gives us a very different picture of the subject-object relation than we get in bourgeois economics. Rather than a free society of empowered individuals who are free to act upon their abstract desires and take full-responsibility for their lot in life, Marx’s critique of the capitalist mode of production reveals a world in which individuals are at the mercy of the coercive laws of the market. The sorts of superficial freedoms they have to choose between coke and pepsi pale in comparison disciplining of our lives to SNLT and the pursuit of profit. (images of clocks)

Subject/Object inversion

[Mitt Romney quote about corporations being people]

There is a lot of talk in the Occupy Wall Street movement about ending “corporate personhood”. The problem with this demand is that the legal status of corporate personhood is just the icing on the cake. In a capitalist society corporations are much more like people than people are. Capital is the active subject and people its object. This is what Marx means by “subject/object inversion.” Rather than people being the active agents of the social order it is the “objective” logic of the market that dominates the subjects. Blind economic laws rule and people obey. Money becomes more powerful than people. Corporations become people and exert more power in society than individuals or even social movements. While people run around in the street with signs begging the system to take notice of them, the cold-logic of capital becomes the active agent in society, using the body of the worker like a passive expendable commodity, subordinating societies, governments and even nature itself to the impersonal motives of profit.

The crazy thing is that this “objective” world is still just the product of our own creation. We actively reproduce it everyday. This is the core of what makes Marx’s critique of capitalism so powerful: The world we live in, despite the incredibly disempowering structure of our current situation, is always only the result of our own actions and we do have the ability to collectively change it. But in order to exercise such collective power we must break with the capitalist mode of production.

Now…. do you get any of that heavy stuff with marginalism?

conclusion:

In case you were wondering Subjectivist Island and Barter Island don’t exist. They are abstractions. Now every theory needs abstractions- we must sift through a world of data and identify the broad contours and important categories that define reality. Subjectivist and Barter Islands are “ideal abstractions”, that is, abstractions that exist only in the minds of philosophers. [footnote on praxeology] Marx makes a different kind of abstraction, a “real abstraction”. A real abstraction is not made by philosophers arbitrarily leaving out parts of social reality. A real abstractions is made by reality itself.

In a capitalist society human labor becomes abstract. In the caste system of feudalism where people were born into certain types of work and there were strict divisions between castes there was no such thing as labor in general, or a worker in general. But in a capitalist society labor loses all of these specific features. Capital treats us like anonymous digits in a profit-calculator, moving us from place to place in the search for profit. Our labor becomes abstract labor. We become, not peasants, knights, or artisans, but workers in general. Marx’s theory of value is based on this real abstraction that is made by the mode of production itself, not the minds of philosophers.

This doesn’t mean that the perspective of marginalism comes from nowhere. Marginalism comes from a real existing standpoint within capitalism, the standpoint of the atomized individual contemplating commodities. This standpoint is real. We experience it everyday at the grocery store. But it is an incomplete perspective because it leaves out the entire world of social production that puts commodities on the shelves and money in our pockets. This perspective is the perspective of commodity fetishism, in which the social power of our own labor takes the form of inherent properties of objects.

But in times of economic crisis we see cracks in the walls of this reality. Old ways of thinking lose their relevance. Crises are a time when the economic laws of capitalism are exposed not as eternal, universal laws as the bourgeois economists would want us to think, but as the particular laws of this time, laws that we might be able to overthrow. As the law of value breaks down, as people start to question the order of things, the capitalist state must enter the picture, replacing the failing law of value with the brutal law of the state. The charming, freedom-loving world of the market apologists (ron paul picture) is revealed for what it really is, an exploitative order based on violence.

Like a schoolyard bully, a system is always the most violent when its weakness is exposed. When the law of value breaks down the politics begin. Subjects must become active. This can be the politics of the ruling class as it scrambles to reassert the status quo or it can be the politics of radical movements that posit the possibility for new social orders.

Law of Value 4: Value

Use-Value, Exchange Value, Value

part 4 of the Law of Value series

This is one of many abandoned houses in my neighborhood. The slumlord owner let the property deteriorate until it became unlivable and doesn’t want to pay the money to make it livable again. There are thousands of abandoned houses in this city, and thousands of homeless people. Despite the urgent social need for houses these properties don’t fulfill a social use. Why not? Because the owners of these commodities are not interested in their use. They are interested in their exchange-value, the rent they receive from the property. For decades they collected rent while the use-value of the house deteriorated. And now these houses sit vacant, a testament to the contradiction between use-value and exchange-value.

This is not a contradiction restricted to housing. Every commodity contains this contradiction because every commodity is produced to be exchanged, not to be used by the producer. We have enough food on the planet to feed everyone, yet millions starve. Why? Because we don’t produce food directly for social need. We make food in order to sell it for money. Society has much of the technological ideas it needs to reduce greenhouse gas emissions, yet it isn’t acting fast enough to apply these ideas. Why? Because production is not undertaken to direct   ly mediate our relation with the environment. We produce for profit.

The exchange of the products of labor in the market is just one of many possible ways that the private labors of billions of individuals can be coordinated. Some people think this is the best possible way to coordinate human productive activity. Marx saw that, despite all of the dynamism and technological wizardry of capitalism, there were fundamental social antagonisms at the heart of this means of coordination… that production for market exchange leads to all sorts of unexpected consequences including gross inequality, exploitation, and crisis. And for Marx all of these social antagonisms can’t be understood until we understand the contradiction within the idea of a commodity itself: the contradiction between use value and exchange value.

Use value vs. exchange value

A commodity has a use. This is its use-value. What does use-value tell us? It tells us how a commodity satisfies a social need. If we want to feed everybody we need a certain quantity of food. If we want to build everyone a house we need a certain quantity of wood and nails. Some use-values require no effort to attain: air, sun, gravity, etc. Others require effort to attain. There is a finite limit to the amount of labor that can be devoted to the production of use-values. Society must apportion this labor between the production of different use-values in some way. As technology changes the amount of labor required to produce some use-values decreases thus signaling a change in the apportioning of labor. As technology evolves to reshape what human labor is capable of producing so do our needs and desires evolve.

In different societies this labor is apportioned by different methods. In a market society it is the buying and selling of the products of labor in the marketplace that serves the purpose of allocating labor between the production of this use-value or that use-value. This creates a second type of value, unique to market societies: exchange-value.

Exchange value is the ratio in which one good exchanges for another. Perhaps one book exchanges for a loaf of bread… Or a new car exchanges for a thousand bottles of whiskey. These ratios are all exchange values. They say a book is worth this much bread; a car is worth this much whisky. In a developed market society one commodity eventually emerges as the primary commodity in which all other commodities express their exchange value. This is what money is. For most of the history of capitalism this commodity has been gold. By comparing the ratio of tomatoes or cars or baseballs to gold all commodities measured their exchange value in ratios to gold.

These two sides of the commodity, its use-value and exchange value, form two opposing, contradictory poles.  Much of the social antagonisms of capitalism are rooted in this tension between use-value and exchange value. Of course, most of the time when we look at a commodity it doesn’t seem very antagonistic. This is because the antagonistic social relations behind the commodity are not visible. But when we look at a society organized around commodity exchange we can see lots of social antagonisms.  To understand how these social antagonisms spring from the opposition of use-value and exchange-value we will need to take a closer look at both…

You can’t use it AND exchange it!

If I am selling a tomato this tomato has no use-value at all for me. Its use-value only exists for the person that buys it. I am only interested in the exchange-value, how much money I can get for it. Production in a capitalist society is not production for use, but for exchange. This means that we have no inherent interest in the usefulness of our labor outside of its ability to create exchange-value. Now, from a social perspective, it is very important what kind of labor we do: Do we make bombs or flowers? Oil or cupcakes? But as individuals we have no stake in this. We produce in order make money, to get exchange value.

Why do people produce for exchange and not for their own use? Because in a capitalist society the working class does not own the means of producing their own subsistence. The only way for working people to get the necessities of life is buy them in the market. And the only way to do this is to sell our labor to a capitalist for a wage. We spend our whole life making a profit for an employer so that we can spend this wage in the market to obtain our daily bread. Our job is not a means toward personal satisfaction. Our job is a means of making money so that we can buy our satisfaction in the market.

Bourgeois subjective value theory talks about a “double-inequality of exchange.” It says that the only reason exchange happens is that two people value the other person’s product more than the product they are giving up. Marx actually goes even further than this. He says that to the seller the commodity has no use-value at all, other than the fact that it can be exchanged.

Not only does this bourgeois theory of “double-inequality of exchange” give the mistaken impression that people produce for their own wants and then sell off the surplus in the market, but it also imposes the profit-maximizing logic of the capitalist onto the consumer. By claiming that consumers make a subjective profit from exchange it transposes the real, objective profit of a capitalist who pays his workers one sum of money and sells the products of their labor for a greater sum of money, onto a completely intangible and unquantifiable notion of subjective profit. But subjective preferences for commodities can’t be measured, divided, added to, or compared in a numerical fashion. By imposing the logic of capital onto consumers it effectively erases class from the scope of its analysis.

The mystery of exchange value…

One book=  1 car. What does that mean? What does it mean to say something is worth so much of something else?
Some people think that the usefulness of a commodity can answer this. But uses of things can’t be compared. You read books. You drive cars. They are two totally unrelated and incomparable uses. Maybe you like books more than cars. Does this mean that books are worth more than cars? (1)

What does it mean to say a book is worth so many jars of peanut butter, or so many cups of coffee? Clearly jars of peanut butter or cups of coffee are measuring something. And clearly any other commodity could be used to measure this something. A book could be worth so many pencils, so many kittens, so many tires… And each of these exchange values would be a different way of measuring the value of the book.

But this means that the book has a value independent of the particular commodity that we choose to measure it with. Whether we measure the book’s value in beers, beans or kittens it stays the same. Yet we can’t see this value. We only see the specific exchange ratios of the book as it is exchanged with other commodities. [The only thing that changes is the "form of appearance" of this value- the particular manifestation of this value.] But isn’t this what exchange value really is- the comparison of the value of one commodity with the value of another? These exchange-values only make sense, only work, because there is something called value that is being measured by them. Exchange value necessarily implies the presence of an underlying value. Marx uses the term “intrinsic value”. By this he doesn’t mean that value lies buried within the commodity, or that it is magically bestowed upon the commodity, but that it is impossible to compare commodities to each other in the market without a commodity having its own value. But what is this value?

What is the 3rd thing?

We have seen that exchange value implies that commodities have an intrinsic value expressed in different exchange ratios. This value is not use-value or exchange-value but a 3rd thing. What is this value? Where does it come from?

I know you are in a lot of suspense so I’ll just come right out and say it: Marx argues that it is the labor time that society devotes to the production of these commodities that accounts for this underlying value. Commodities that take more labor to create have more value than ones that take less labor. As labor becomes more productive, as it becomes easier to produce things, their value falls. But what is Marx’s justification for choosing labor as this 3rd thing?

Marx’s critic Bohm-Bawerk pointed out that there are lots of properties that are common to all commodities: Marx could just as easily have said scarcity or utility were this third thing. This, of course, is the approach taken by marginal utility theory which argues that it is our subjective desires for commodities in relation to their scarcity that determines their value. Why is it that Marx doesn’t take this route?

For one, scarcity and utility cannot be understood without reference to labor. The amount of a commodity that exists at any point in time is clearly related to the amount of labor that has been devoted to producing that commodity. And utility isn’t just some abstract, individual substance detached from the labor process. Subjective desire only counts economically when it is turned into real action, when we buy things in the market. The only way to enter the market as a purchaser is to also enter it as a seller. We must sell the products of our labor and then use this money to buy the commodities we desire. (More specifically, workers sell their ability to work, their labor power, to an employer. The employer sells the product of that labor in the market. Workers receive a part of this value in the form of a wage.) The only means of attaining our desires is the buying and selling of the products of labor. Not only does capitalism shape our desires, it determines how we go about attaining our desires.

But there is an even more important reason why Marx doesn’t choose scarcity and utility as the determinants of this underlying value. Utility and scarcity both describe the relation between individuals and objects. Marx is interested in the relations between people. If we think back to Marx’s argument about commodity fetishism we will remember that in a capitalist society the relations between people take the form of relations between things. Objects appear to have power and value, on their own. But this wold of appearance is not the full story. These value relations between commodities are actually relations between people whose work is coordinated indirectly through commodity exchange.

And this is where any social theory must begin: with a study of the productive activity of people as they work to create the world  they live in. Not only is this the best starting place for an analysis of society, it is also the best starting point for a radical social theory whose aim is to investigate the possibility of changing the world. If we realize that human society is not the result of some natural or divine eternal logic but merely the creation of our own labor then that means that we have the power to mold and shape that society as we see fit. In a capitalist society these creative powers take the form of an external world of value and capital that acts back upon society, shaping it against the will of its creators. Yet, in the end the world of capital is nothing but the product of our own creation. If we truly want to change the world it is not up to nature, God, fate or experts, but up to us. This is the radical challenge of the law of value.

Let’s review and clarify:

1. The usefulness of a commodity is its use-value. Uses can’t be quantitatively compared.
2. The exchange-value of a commodity is the proportions at which it exchanges with other commodities.
3. Price is a specific type of exchange-value, the ratio at which a commodity exchanges with money.
4. The fact that commodities measure their worth against each other implies that they have an intrinsic value.
5. This intrinsic value is not a physical thing, nor is it magically bestowed upon commodities. It is not a timeless trait existing for all products of labor everywhere. Value, in the way Marx uses the term, is the means by which the labors of isolated producers are coordinated through commodity exchange. It is the social substance the binds together the labors of isolated, disparate individuals separated through the market.

Price and Value (a brief distinction)

We notice then that value and price are not the same thing. The value of a sandwich may be 1 hour of labor. Yet we don’t see this 1 hour when we buy a sandwich. All we see is its price. Prices are just the exchange value of commodities measured in money. The only way we see value is indirectly through these quantitative relations between commodities. Though value and price are indirectly linked, their connection is still strong. If demand rises suddenly causing the price of sandwiches to rise this will trigger an inflow of sandwich-making labor to meet demand. And once demand and supply have balanced, price falls back down to meet value. If the productivity of sandwich-making rises the time it takes to make a sandwich falls. The supply rises and the price falls. Prices and values fluctuate around each other, constantly codetermining each other.

Conclusion

The last thing we should note is that this concept of value is historically specific. Unlike bourgeois economic theory which projects its categories of utility and capital back in time to make all of history retroactively bend to the laws of capitalism, Marx’s theory of value describes a specific type of social organization unique to a society in which the dominant form of production is production for market exchange. When we don’t produce directly for use, but for exchange, we find that our productive activity is regulated by unconscious economic laws which Marx calls the “law of value”. Whereas before we said there was an antagonism between use-value and exchange-value we can now say that this is really an antagonism between use-value and value (since exchange value is an expression of value). As long as production is production to produce values instead of uses we will have to deal with the social antagonisms that spring from this contradiction: The logic of profit will dominate over society rather than the logic of usefulness. And the nature of work will be to maximize profit at all cost rather than to maximize the quality of the experience of work or of the life of the worker.

Footnotes:

1. There have been attempts by neoclassical economists to reduce the usefulness of commodities to some common substance. Since there is no common substance that makes up usefulness they have to make up an imaginary substance called “utles”. These economists actually say things like, “A cup of coffee has 13 utles and a car has 3000 utles of utility”. But such attempts to invent imaginary substances with which to reduce utility to are generally thought to be pretty silly and misguided. In neo-classical economics this concept has been mostly replaced by the concept of rank preferences, or graded utility: A consumer has a ranking of demand preferences but these can’t be reduced to some common scale. In this way the question of value, in the sense that a commodity has a definite amount of value as determined by subjective social demand, is mostly abandoned: Commodities don’t have values, but consumers have preference rankings and these preference rankings result in prices. This approach conveniently eliminates many of the theoretical problems with earlier marginal utility theory (namely the unquantifiable nature of subjective utility), yet it has an inherent circularity: consumer preferences are not formed in a vacuum. They are formed on the basis of preexisting exchange ratios. As the prices of commodities change so do the preference rankings of commodities. So commodity prices must first be assumed in for marginalists to theorize the subjective processes of price formation. This is circular. The pink elephant in the room is the productivity of labor. As this productivity changes so do prices. There are a host of other criticisms lodged at Marginalism by Marxists. Perhaps sometime in the future I can write/produce more on the topic.
