Use-value

Use value (German: Gebrauchswert) or value in use is the utility of consuming a good—the want-satisfying power of a good or service in classical political economy. In Marx's critique of political economy, any product has a labor-value and a use-value, and if it is traded as a commodity in markets, it additionally has an exchange value, most often expressed as a money-price. Marx acknowledges that commodities being traded also have a general utility, implied by the fact that people want them, but he argues that this by itself tells us nothing about the specific character of the economy in which they are produced and sold.

The concepts of value, use value, utility, exchange value and price have a very long history in economic and philosophical thought, from Aristotle to Adam Smith, and their meanings evolved. Adam Smith recognized that commodities may have an exchange-value but may satisfy no use-value, such as diamonds, while a commodity with a very high use-value may have a very low exchange-value, such as water. Marx comments for example that "in English writers of the 17th century we frequently find worth in the sense of value in use, and value in the sense of exchange-value." With the expansion of market economy, however, the focus of economists has increasingly been on prices and price-relations, the social process of exchange as such being assumed to occur as a naturally given fact.

Marx emphasizes that the use-value of a labor-product is practical and objectively determined; that is, it inheres in the intrinsic characteristics of a product that enable it to satisfy a human need or want. The use-value of a product therefore exists as a material reality vis-a-vis social needs regardless of the individual need of any particular person. The use-value of a commodity is specifically a social use-value, meaning that it has a generally accepted use-value for others in society, and not just for the producer.

Marx first defines use-value precisely in A Contribution to the Critique of Political Economy (1859) where he explains that:

"To begin with, a commodity, in the language of the English economists, is 'any thing necessary, useful or pleasant in life,' an object of human wants, a means of existence in the widest sense of the term. Use-value as an aspect of the commodity coincides with the physical palpable existence of the commodity. Wheat, for example, is a distinct use-value differing from the use-values of cotton, glass, paper, etc. A use-value has value only in use, and is realized only in the process of consumption. One and the same use-value can be used in various ways. But the extent of its possible application is limited by its existence as an object with distinct properties. It is, moreover, determined not only qualitatively but also quantitatively. Different use-values have different measures appropriate to their physical characteristics; for example, a bushel of wheat, a quire of paper, a yard of linen. Whatever its social form may be, wealth always consists of use-values, which in the first instance are not affected by this form. From the taste of wheat it is not possible to tell who produced it, a Russian serf, a French peasant or an English capitalist. Although use-values serve social needs and therefore exist within the social framework, they do not express the social relations of production. For instance, let us take as a use-value a commodity such as a diamond. We cannot tell by looking at it that the diamond is a commodity. Where it serves as an aesthetic or mechanical use-value, on the neck of a courtesan or in the hand of a glass-cutter, it is a diamond and not a commodity. To be a use-value is evidently a necessary prerequisite of the commodity, but it is immaterial to the use-value whether it is a commodity. Use-value as such, since it is independent of the determinate economic form, lies outside the sphere of investigation of political economy. It belongs in this sphere only when it is itself a determinate form. Use-value is the immediate physical entity in which a definite economic relationship – exchange-value – is expressed."
