The Nature and Necessity of a Price System

Joseph A. Schumpeter’s “The Nature and Necessity of a Price System” is a short single-author theoretical essay reprinted from Economic Reconstruction (1934). Its scope is deliberately compact: it is not a general defense of capitalism, but an intervention in debates over reconstruction that treated prices and profits as removable barriers to abundance. The essay’s three sections move from that polemical setting, to a theory of price as choice under scarcity, to a qualified account of perfect and imperfect competition.

In order to show that price is a phenomenon incident to all forms of organization of society and to economic action in general, it is sufficient to look upon it as a coefficient of economic choice.

This definition is the essay’s central conceptual move. Schumpeter detaches price from its specifically capitalist appearance as a money payment and defines it more generally as a quantitative index of preference among alternatives. At the margin, paying for one good rather than another expresses a ranked choice under scarcity. The point is then applied to a centralized socialist economy: planners would still need citizens to register wants with “quantitative precision,” and claims on general product would reproduce the function of prices.

If then prices can be considered to be coefficients of choice, then the coefficients of choice of the comrades would be essentially prices.

The argument is not confined to consumer goods. To decide how to produce, managers must also impute values to means of production according to the alternative uses they make possible. Schumpeter’s example of producing whisky rather than bread from rye shows that production cannot be divided into an economic “what” and a merely technical “how.” Methods differ in their use of scarce factors, so a technically superior process may be economically irrational if it consumes too much of a scarce input.

Hence rational production can never rest on exclusively technological considerations, at least not as long as all means of production are not at the command of a society in unlimited quantities.

Thus the “necessity” of a price system is the necessity of some common economic dimension for comparing wants, alternatives, and productive means. These coefficients need not be numerically identical across institutions, and they need not always appear as capitalist market prices; but any society facing scarcity must discover and use something fulfilling that role. Schumpeter’s target is therefore the fantasy of abolishing price-like calculation altogether.

The third section complicates any easy laissez-faire reading. Schumpeter accepts the analytical importance of perfect competition, but sharply limits its practical application. The ideal may support claims about maximum product, though not straightforwardly maximum welfare, only under a condition in which no buyer or seller can influence price. Modern large-scale production, however, makes that condition unrealizable, and results from perfect competition cannot simply be transferred to actual markets.

On the contrary, it has been proved of late that in important respects imperfect or monopolistic competition will produce exactly the opposite of those results which might be expected from free competition in the theoretic sense.

Here Schumpeter grants partial force to popular and reformist criticism. The “man in the street” often means by competition merely the absence of explicit agreements or outside interference, while the real situation may still be monopolistic competition. Inertia, friction, restricted output, and profits from limited competition can generate waste and stop production short of both technical and economic optima. He also distinguishes such profits from those that have served as “prime movers” of progress.

The diagnostic value of the theory of free competition in the pure sense is, however, not impaired by these considerations.

The essay ends by preserving pure competitive theory as a diagnostic instrument rather than a description of capitalism. Money does not alter the nature of coefficients of choice, though monetary and credit mechanisms may cause disturbances. Stability proved for competitive equilibrium does not extend to limited competition. Even a perfectly competitive system would be vulnerable to external shocks, including a hostile social environment. The essay’s lasting relevance lies in this double refusal: anti-price reform is incoherent because scarcity requires price-like calculation, but actual capitalism cannot claim the virtues of an unrealizable competitive ideal.
