Friedrich A. Hayek, “Marginal Utility and Economic Calculation: A Review” (1925)

Hayek’s essay is a compact review of Leo Schönfeld’s Grenznutzen und Wirtschaftsrechnung, the introductory volume of a projected larger study. Its tone is provisional but serious: Hayek is not merely announcing a new book, but locating it within a stalled tradition of general economic theory and asking whether it can reopen problems left unresolved by the Austrian school’s earlier synthesis.

New life seems to be stirring in the field of general economic theory which has been very much neglected during the last decade.

The review begins from the sense that Austrian marginal utility theory had reached both culmination and impasse. Wieser’s great system had organized subjective value theory with such force that it became difficult for younger theorists to see where further advance was possible. Hayek treats this not as a refutation of Wieser, but as the paradoxical effect of a work whose completeness made continuation seem unnecessary or forbidding.

It was also to remain the last noteworthy achievement in this field for a long time.

Schönfeld matters, for Hayek, because he does not simply repeat the inherited doctrine. He tries to connect marginal utility with “economic calculation”: the concrete procedure by which an economic subject allocates goods among possible uses. The review’s central interest lies in this shift from value as a result to valuation as a process. Hayek is especially attentive to Schönfeld’s distinction between a logically complete calculation, in which all possible uses and combinations would be compared, and the abbreviated methods actually available in practice.

This distinction gives the book its theoretical importance. Marginal utility is no longer treated as an isolated datum from which action follows mechanically. It becomes part of a wider account of how agents compare, revise, and simplify decisions under conditions of interdependence. Hayek sees here a potentially fruitful way of handling problems that become obscure if wants are treated as a fixed list and goods as independently assignable to them.

Its effect on the younger generation of researchers seems for the time being to have been more that of discouragement than stimulation.

Hayek’s praise is therefore closely tied to his account of the field’s stagnation. Schönfeld’s book appears as evidence that subjective value theory can still generate new problems and methods. Its significance lies not in stylistic novelty, but in its effort to make calculation itself an object of theory. By asking how total economic utility is approached through combinations of decisions, Schönfeld pushes marginal utility theory toward the systemic character of actual economic choice.

Yet Hayek also identifies the difficulty created by this advance. If each use of a good gains its economic meaning only within a whole arrangement of uses, then isolated marginal comparisons may be misleading. A change that looks inferior when considered alone may be part of a superior overall combination. But if theory responds by comparing whole states directly, it risks abandoning explanation and merely recording choices as facts. The review’s most important tension is therefore between the need for a comprehensive account of total utility and the need to preserve an intelligible marginal procedure.

Hayek also notes Schönfeld’s constructive concepts: the treatment of uses as combinations of decisions, the idea of economic quid pro quo, the reformulation of diminishing wants, and the principle of economic relevance as a way of limiting the comparisons required for calculation. These elements are not presented as a finished system. Rather, they show the rigor and ambition of an inquiry that tries to extend Austrian theory without dissolving it into either psychology or formal tautology.

Among these, the work by Schönfeld which is the subject of this review appears to us to be especially worthy of attention for several reasons.

The closing judgment is admiring but guarded. Hayek stresses the book’s clarity and intellectual maturity while recognizing that the introductory volume cannot settle the larger issues it raises. Its lasting interest lies in the early formulation of themes that would remain central to Hayek’s own thought: economic order as a problem of calculation, the limits of static value data, the interdependence of decisions, and the need to explain action without reducing it to either mechanical deduction or unexplained choice.

It also and above all stands out by its unusual maturity and clarity of exposition and by the method of procedure adopted by the author, a method which is extremely conscientious and, in its completeness, ‘exact’ in the best meaning of the word.
