Carl Menger and the Subjectivist Tradition in Economics

This file is a single-author scholarly chapter/commentary in history of economic thought. Occasioned by the facsimile republication of Menger’s Grundsätze, it reassesses Menger from the standpoint of the mature Austrian tradition. Kirzner’s thesis is that Menger’s revolution was not simply diminishing marginal utility, but a new way of seeing the economy as a teleological order in which production, exchange, prices, wages, rent, and interest all express subjective valuations.

For Menger the entire economic system is seen as a complex of activities directly or indirectly inspired by the goal of satisfying consumer needs.

Kirzner uses this claim to answer Frank Knight’s objection to Menger’s treatment of production as the conversion of higher-order into lower-order goods. For Kirzner, that language is the breakthrough. Production is not merely a technical rearrangement of coal, iron, labor, and tools; it is the purposeful bringing of means closer to want-satisfaction. A resource has economic significance only insofar as someone judges it capable, directly or indirectly, of serving final consumption. The ordered structure of goods lets Menger unify product prices, factor prices, rent, wages, and interest.

This perspective transmutes all the phenomena of the economy from being simply physical transformations, relationships or ratios into direct or indirect expressions of human valuations, preferences, expectations and dreams.

This is why Kirzner separates Mengerian subjectivism from the standard marginal-utility story. Marginal utility is foundational, but Menger extends the same logic through the entire production structure: factor prices and distribution are indirect expressions of consumer valuations, not separate classical problems. The economy becomes intelligible as a network through which the importance of final wants is imputed back to higher-order goods.

The chapter then pivots to immanent critique. Menger founded Austrian subjectivism, but did not carry it far enough. His theory of “needs” remains partly objectivist, as if definite urgencies impose themselves on conduct apart from freely chosen purposes. More importantly, he often writes as though consumer valuations automatically transmit themselves to the prices of land, labor, capital, and intermediate goods. Kirzner clarifies the problem through Hayek’s criticism of Schumpeter: Schumpeter assumed that valuing final goods ipso facto values the means of production, while Hayek insisted that such a deduction would be possible only to an omniscient mind.

This lapse in Schumpeter’s subjectivism, we wish to submit, parallels precisely a corresponding lapse in Menger’s subjectivism.

The missing concept is entrepreneurship. In later Austrian theory, consumer preferences reach factor markets only through alert, imaginative, profit-seeking actors who discover possibilities under uncertainty. Market prices are not the mechanical consequence of given wants; they emerge from rivalrous attempts to interpret dispersed knowledge. Menger saw that higher-order goods derive value from lower-order goods, but not the uncertain market process by which such derivation is discovered.

Kirzner sharpens the point in the section on perfect knowledge. Menger recognized error and imperfect information, yet treated them as “pathological” departures from economic law. Kirzner allows equilibrium theory as a separate inquiry into positions toward which prices may gravitate. The trouble is treating that abstraction as normal market life. From a Mises-Hayek standpoint, ignorance creates opportunities and makes discovery necessary.

Nowhere, in brief, does Menger display a sensitivity to this dimension of the subjectivism upon which market forces in fact depend.

The methodological digression on essentialism explains why Menger differs from Walrasian or Knightian price theory. Drawing on Hutchison, Kauder, and Mäki, Kirzner presents Menger as seeking the Wesen, the essence, of economic phenomena rather than only functional relations among variables. Costs and constraints affect price levels, but the essence of price lies in purposive valuation.

For Menger the essence of both agricultural regimes is their being inspired by (and explained by) consumer needs for bread.

The structure is cumulative: reconstruction of Menger’s teleological production theory; expansion of subjectivism beyond marginal utility; diagnosis of its incomplete treatment of knowledge, error, and entrepreneurship; recovery of Menger’s essentialist method; and placement of Menger at the head of the Austrian line leading to Mises and Hayek. Kirzner’s judgment is double: the Grundsätze founded subjectivist economics, but its full implications required later non-equilibrium theories of calculation, competition, and market process.
