Perfect competition earns its keep here not as a description of any real market but as the benchmark against which every messier case is measured, and messier cases, this 1934 review essay argues, are where most economic life actually sits. Assessing Joan Robinson's Economics of Imperfect Competition, Schumpeter fixes on marginal revenue as her decisive analytical discovery, the tool that restores symmetry to demand-and-supply reasoning and unifies pricing across competition, monopoly, and the territory between. He credits the book's rigor and teachability while faulting its cost: a resolutely Marshallian, two-variable, partial-equilibrium frame that forgoes indifference curves and Walrasian generality. Imperfect-competition analysis, he warns, overturns welfare and policy verdicts, sometimes into the exact opposite of what they were twenty years before.
For any science or part of a science, the first task always consists in establishing the logical autonomy of its field, or rather the conditions under which there is logical autonomy.
