Carl Menger, Grundsätze der Volkswirthschaftslehre — Summary

Carl Menger’s Grundsätze der Volkswirthschaftslehre (1871) is the “first, general part” of a projected reconstruction of economics. Rather than beginning with classes, nations, or labor quantities, Menger begins with the causal relation between human wants and the means capable of satisfying them. A thing becomes a good only when it is causally connected to a want, when that connection is known, and when command over it is possible. His famous distinction between lower-order and higher-order goods then lets him explain production without making cost an independent source of value: tools, raw materials, land uses, and labor services matter economically because they help bring about future satisfactions.

Scarcity is the hinge of the system. Goods become economic when available quantities are insufficient for all desired uses; where supply exceeds need, things may remain useful but cease to be objects of economizing. Menger therefore denies that usefulness alone creates value.

Die nicht ökonomischen Güter haben demnach nicht nur, wie dies bisher angenommen wurde, keinen Tauschwerth, sondern überhaupt keinen Werth, und somit auch keinen Gebrauchswerth.

English translation: Non-economic goods therefore have not only, as hitherto assumed, no exchange value, but no value at all, and consequently also no use value.

Value, for Menger, is not an intrinsic property of goods and not labor embodied in them. It is the significance a concrete good has for an economizing person who recognizes that some satisfaction depends on command over it. Its measure is governed by the least important satisfaction that would be lost if one unit of the available stock disappeared. In this way Menger formulates the marginal principle as a causal theory of valuation rather than as a mathematical apparatus.

Der Werth ist demnach nicht nur seinem Wesen, sondern auch seinem Masse nach subjectiver Natur.

English translation: Value is therefore subjective in nature not only in its essence but also in its measure.

This subjective theory also reverses classical cost doctrines. Goods of higher order receive value by imputation from the lower-order goods they help produce; expected product value governs the value of productive means, not the other way around. Menger thus preserves a rigorous account of production while denying that costs can ultimately explain value independently of wants, scarcity, and anticipated satisfactions.

The analysis of exchange follows directly. Exchange does not rest on equality of value, but on inequality of valuations: each party gives up what is less important to him in order to obtain what is more important. Price forms within limits set by the valuations of buyers and sellers. Menger’s distinction between use value and exchange value clarifies that an economizing person compares alternative employments of the same good.

Es ist demnach in allen Fällen, wo ein Gut für dessen Besitzer sowohl Gebrauchswerth, als auch Tauschwerth hat, derjenige der ökonomische, welcher der grössere ist.

English translation: In all cases in which a good has for its possessor both use value and exchange value, the economic value is whichever of the two is the greater.

Menger applies the same causal logic to monopoly and competition. A monopolist’s conduct is not explained by a special moral psychology but by control over a scarce supply and by the attempt to select the quantity that yields the greatest proceeds.

Seine Wirthschaftspolitik geht rücksichtlich der ihm verfügbaren Quantitäten des Monopolgutes auf den möglichst grossen Erlös.

English translation: His economic policy with respect to the quantities of the monopoly good available to him is directed toward the greatest possible yield.

Competition alters this situation by introducing rival sellers and limiting the gains from withholding. Yet competitive price, like monopoly price, remains grounded in subjective valuations and scarcity rather than in objective equivalence.

The final movement of the book treats commodities and money. A commodity is a good held for exchange rather than direct use. Money emerges because some goods are more saleable than others: individuals trying to overcome the limits of barter gradually accept highly marketable goods, not for immediate consumption, but because they can more easily be exchanged again. Money is therefore presented as an unintended social institution arising from individual economizing action, not primarily as a legal creation.

The importance of the Grundsätze lies in the unity of this reconstruction. Menger derives value, production, price, monopoly, competition, commodities, and money from the same foundation: purposeful action under scarcity. Its originality is not only the claim that value is subjective, but the systematic use of that claim to rebuild economic theory around marginal significance and causal-genetic explanation.
