The labor theory of value
A recurring theme on this blog is the different conceptions of value and the resulting effect on worldview and policy because I am fascinated by how such a philosophical dispute can impact real-life. I suspect that a subjective theory of value (which I support) leads to acceptance of free markets, and that objective theories of value (which I disparage) lead their rejection. For a deal can provide subjective value to both participants, whereas if the important measure of value is objective (and it's quantity conserved), an exchange transfers value from one to another, and all profit becomes theft. The consequences are profound!
When arguing with haters of capitalism, like a grappler who takes the fight to the ground, I prefer to head straight to these fundamental differences rather than bickering over their conclusions. However, since most people lack the stamina or bravery to inspect their premises, I find few takers. In my new friend Professor Andrew Austin it seemed I had discovered a leftist with the wherewithal to get to the root, but unfortunately he too tired of discussing essentials, preferring to return to writing monologues about the election circus, leaving me to wallow in what he called my “mythology”.
My viewpoint is considered a subjective theory of value because the only two types of value I recognize, expected utility and price, are subjective. The expected utility is the amount of usefulness or enjoyment an individual predicts a good or service will provide. The price of a successful sale, being bounded by the customer's expected utility, is equally subjective.
To what could the idea of “objective value” possibly refer? The word “value” begs the question “of value to whom?” Evaluation implies awareness. Value lacking an evaluator is a purely metaphysical entity, a figment of mystical language.
Undeterred, proponents of an objective theory add to those two types of value at least one more. The most popular form, expounded by Marx, is based on labor. Here the value is equivalent to the average amount of time generally required to create the object. Marxists are quick to demand bourgeois credibility by pointing out that the labor theory of value comes from earlier, more conservative economists. Nevertheless, I will explore the labor theory of value as interpreted by Ernest Mandel in An Introduction to Marxist Economic Theory. He writes:
As soon as a regular system of exchange between the farmer and the textile craftsman was established, standard equivalents were likewise established -- for example, an ell of cloth would be exchanged for 10 pounds of butter, not for 100 pounds. Obviously the peasants knew, on the basis of their own experience, the approximate labor-time needed to produce a given quantity of cloth. Had there not been a more or less exact equivalence between the time needed to produce the cloth and the time needed to produce the butter for which it was exchanged, there would have been an immediate shift in the division of labor. If cloth production were more lucrative than butter production, the butter producers would switch to producing cloth.
If an hour's quantity of cloth is equivalent to an hour's quantity of butter, how could anybody determine that production of one was more lucrative than the other? Nevertheless, we have determined that an ell of cloth had a exchange-value of one hour, and that 10 pounds of butter also had an exchange-value of one hour.
The exchange-value of a commodity is determined by the quantity of labor necessary to produce it. The quantity of labor is measured at the length of time it takes to produce the commodity. Expressed another way, the exchange-value of a commodity is not determined by the quantity of labor expended by each individual producer engaged in the production of this commodity, but by the quantity of labor socially necessary to produce it.
Exchange-value must be measured in hours. Now let's explore the concept of surplus-value.
We can therefore say from here on that surplus-value is the difference between the value produced by the worker and the value of his own labor-power. What is the value of labor-power? In capitalist society, labor-power is a commodity, and like the value of any other commodity, its value is the quantity of labor socially necessary to produce and reproduce it, that is to say, the living costs of the worker in the wide meaning of the term.
What is the value of labor power in terms of exchange-value? Exchange-value is measured in hours, therefore the value of an hour of labor is exactly 1 hour. There's no possible difference between equivalent quantities. Measured by exchange-value, surplus-value is always zero!
To discover the surplus which provides business profit, we must use the subjective concepts of expected utility and price. For the worker, the expected utility of his wage is higher than the expected utility of his labor. Reciprocally, for the employer, the expected utility of the products are higher than the expected utility of the wage. To be sure, the employer pays a wage less than the expected utility of the laborer's products. However the employer is not an end-user, whose purchase price is bounded by his expected utility of the product, but a reseller, whose expected utility is the difference in purchase and expected resale prices, which reduces his willing purchase price. In this way employment may be approximated as an equipment loan to the worker, who enters into a production agreement with the owner, who is a reseller.
Exchange-value is a notion of dubious metaphysical basis, which is at best useless in the analysis of economic reality.
