Ludwig von Mises’s contribution to an edited volume develops, in eleven sections, a methodological account of subjective value theory and its implications for economic calculation. Its central claim is that economics cannot distinguish “economic” from “noneconomic” conduct by motives or objects: all conscious action involves choosing among alternatives. Subjectivism therefore extends economic categories beyond commerce while preserving a narrower domain defined by monetary calculation. The essay moves from the scope of action through economics’ relations to psychology and technology, then examines calculation, changing data, time, apparent obstacles to theoretical explanation, and costs.
Mises begins by reconstructing economics’ movement from money prices to direct exchange and finally to the choices of an isolated individual. Production, too, exchanges one possible condition for another. Classical theory’s concentration on the merchant encouraged an identification of economic conduct with monetary gain; distinctions between material and immaterial goods were equally inadequate, since people sacrifice possessions for honor, religion, or political ends. Subjectivism makes the actor’s purposes, rather than the observer’s judgment of them, decisive. Rationality denotes meaningful action, not objectively correct means or morally approved ends.
Alles bewußte Verhalten von Menschen stellt sich als Vorziehen eines a einem b gegenüber dar. Es ist ein Wählen zwischen sich bietenden Möglichkeiten.
English translation: All conscious human behavior takes the form of preferring an a to a b. It is a choosing between available possibilities.
Preference supplies the elementary unit of explanation. Mises warns against treating “needs” as independent standards by which actual choices can be condemned: economics encounters needs through conduct and must explain existing prices, not prescribe appropriate ones. The relevant boundary separates action from nonaction, wherever choice is necessary because competing ends cannot all be attained. Dissatisfaction, the possibility of improving one’s condition, and the passage of time make action intelligible.
His treatment of eudaimonism extends this argument. Pleasure and displeasure are formal expressions for attaining or missing desired ends, not commitments to sensual gratification or selfishness. Böhm-Bawerk’s inclusion of everything an individual considers desirable consequently agrees with the developed utilitarian position he sought to distinguish himself from. Different moral commitments change the content of choice without abolishing its structure. Mises accordingly claims universal scope for the logic of action, prior to historical description.
The sections on psychology and technology defend economics’ methodological independence. Explaining prices requires individual actors and concrete units of goods, rather than abstract collectivities or whole categories such as “bread.” Mises distinguishes the historical route by which a proposition was discovered from its justification within a theoretical system. Gossen’s saturation law is derived here from experience concerning the ranking of particular goods and particular wants, not borrowed from psychology. Similarly, diminishing returns follows from treating productive inputs as scarce economic goods. His argument is therefore not presented as wholly detached from experience: its independence concerns how economics interprets the experience relevant to action.
Monetary calculation then explains why everyday language nevertheless isolates a specifically economic sphere. Ranking ends directly is possible, but comparing complex production routes requires a common accounting medium. Money prices permit calculation of expenditures, prospective returns, and realized profit or loss. Mises argues that prices for production goods require private ownership and that comprehensive socialization would therefore remove the means of rationally directing extended production. He presents this calculation argument as economics’ outstanding contribution to politics and historical understanding.
Yet calculation’s indispensability does not make it a universal measure of welfare. Observed prices record past exchanges; entrepreneurs use them through judgments about future conditions. Calculation concerns individual profitability within a market order, not the monetary valuation of human life, culture, or an aggregate social optimum.
Die Geldrechnung ist eben nicht Wertrechnung und schon gar nicht Wertmessung.
English translation: Monetary calculation is precisely not value calculation, and certainly not value measurement.
The distinction protects the ordinal character of valuation: actors rank alternatives rather than measure quantities of value. It also limits what economic theory can predict. Changes in external conditions affect conduct through people’s judgments and purposes, for which Mises finds no fixed quantitative relationships. Theory can establish the direction of consequences under specified conditions; numerical findings remain historically particular rather than universally valid laws.
The discussions of time and “resistances” answer objections that theory describes only an unreal, frictionless world. Time matters both through the distinction between present and future goods and through delayed adjustment to changed circumstances. Investment periods, irreversible commitments, and expectations of falling prices can explain why a price increase does not immediately expand supply. These are data for theory, not exceptions to it. Mises likewise rejects the claim that economic explanation requires unrestricted competition, while maintaining his opposition to interventionist policies.
The concluding section makes opportunity cost the link between individual valuation and the allocation of productive resources.
Für die moderne Theorie sind die Kosten die Bedeutung des nächstwichtigen nicht mehr zur Befriedigung gelangenden Bedürfnisses.
English translation: For modern theory, costs are the significance of the next most important need that no longer receives satisfaction.
Stopping production at the profitability boundary means, in Mises’s account, that its inputs are more urgently required elsewhere. Criticism of that boundary must therefore acknowledge the alternative production sacrificed. Subjective value theory reaches beyond the merchant’s bookkeeping precisely by tracing costs to forgone satisfactions. The essay closes by presenting modern economics as a development of classical foundations, not their destruction: classical difficulties generated the questions subjectivism answered. Its significance lies in joining a general theory of choice to a carefully bounded account of monetary calculation, while grounding Mises’s defenses of market allocation in that connection.
