Profit of enterprise and monopoly profit
As we saw last month, Marx’s prices of production are not identical to the marginal cost = equilibrium prices of “orthodox” bourgeois microeconomics. The biggest difference is that prices of production include not only the cost price and interest on capital but also the profit of enterprise. Modern bourgeois microeconomic orthodoxy holds that in “general equilibrium” any profit in excess of interest will be eliminated by “perfect competition.”
In contrast, Marx—and the classical economists before him—did not believe that competition had any tendency to eliminate the profit of enterprise. Instead, they believed that in addition to interest, there is an additional profit of enterprise that is appropriated by the commercial and industrial capitalists. Profit of enterprise is defined as total profit minus interest. The profit of enterprise must not be confused with monopoly profits. The only monopoly necessary for the profit of enterprise is the monopoly of the means of production by the capitalist class.
True monopoly profits do exist. But within the classical-Marxist tradition, monopoly profit is an addition to the profit of enterprise. Anwar Shaikh affirms that monopoly profits exist but he has little to say about them in his “Capitalism.” Instead, Shaikh is interested in “real competition,” which quickly eliminates any profit beyond the profit of enterprise.
Shaikh’s failure to analyze monopoly profit is in full accord with his rejection of the Monthly Review and heterodox post-Keynesian schools, which often treat any profit, or at least any profit beyond interest, as monopoly profit.
Shaikh’s lumping together of these two quite different theories of a monopoly capitalist stage—the Hilferding-Lenin and the “Monopoly Capital” theories—is in my opinion a legitimate criticism of Shaikh’s “Capitalism” and his “fundamentalist school” in general. In “Monopoly Capital,” Paul Baran and Paul Sweezy were quite clear that they were not simply repeating or writing yet another popularization of the Hilferding-Lenin theory of monopoly capitalism. They found that theory inadequate and developed another, quite different theory of monopoly capitalism.
I believe that Shaikh is correct in seeing the influence of the Leon Walras-inspired theory of perfect competition in “Monopoly Capital” and other theories of modern capitalism influenced or inspired by Baran and Sweezy’s “Monopoly Capital.”
