The commodity law of exchange expresses the abstract conditions in which an economy of independent producers who own or produce their own means of production would self-organize through monetary market exchange. The key idea of Smith’s “long-period method” is the formation of “natural prices” as averages of market prices over many cycles of production that equalize the “advantages and disadvantages” of the various branches of production. The advantages consist mainly, though not exclusively, of the money income the producer receives, and the disadvantages consist mainly, though not exclusively, of the effort required to acquire the skills necessary to the branch of production and to carry on production. Under the commodity law of exchange, natural prices are enforced by the movement of producers (assumed to be freely mobile) between branches of production and make it possible to staff all the branches. These natural prices include the costs of the means of production, but not a markup on those costs to provide a profit.
If we look at the history of the division of labor, a relatively small sector of worker cooperatives has in fact coexisted with capitalist production. This sector never disappears completely but also does not exhibit any tendency to grow and displace the dominant capitalist organization of production.
Capitalist commodity production, by contrast, is carried out by capitalist firms that own the means of production and charge a profit rate on them, and by means of wage labor. Both of these changes in what Marx calls “social relations of production” lead to modifications of the commodity law of exchange. The “advantages” of a branch of production from the point of view of a capitalist firm consist primarily of the profitability of production, and, as Adam Smith points out, specifically the profit rate….
