Ludwig von Mises, Die Lehre vom Gelde

Ludwig von Mises’s short theoretical article, originally published in 1928, surveys the development of monetary economics and argues that money is indispensable to explaining market processes and economic calculation. Its movement is from the history of economic theory through the problems of purchasing power, banking, and business cycles to the methodological limits of analyzing exchange without money.

Mises distinguishes classical economics, founded on the recognition of regular relationships among market phenomena, from the later subjective theory of value. Yet the subjectivist school initially concentrated on direct exchange, leaving money, banking, and fluctuations largely within the classical framework. Its subsequent advance required more than incorporating the quantity theory:

Die Quantitätstheorie bietet wie die Lehre von Angebot und Nachfrage, als deren Anwendung auf das Problem der Kaufkraft des Geldes sie sich darstellt, nur eine Aussage über die Veränderungen eines schon gegebenen Geldwerts; sie sagt über die Bildung des ursprünglichen gegebenen Wertes nichts aus.

English translation: The quantity theory, like the doctrine of supply and demand, of which it presents itself as the application to the problem of the purchasing power of money, offers only a statement about the changes in an already given value of money; it says nothing about the formation of the originally given value.

The distinction between explaining changes in an existing purchasing power and explaining its formation identifies the conceptual task of subjective monetary theory. Mises sketches this research agenda without deriving its solution. He links marginal utility analysis to the measurement of changes in money’s value and, through that problem, to the appraisal of proposals for stabilizing purchasing power.

The article next turns to banking. Mises credits Wicksell with reviving the English Currency School’s problems and regards the displacement of Banking Theory as a condition for progress in business-cycle theory. In his account, treating the circulation of fiduciary media as “elastic” had obstructed that progress. Monetary theory consequently has immediate practical significance for central-bank policy, interest-rate policy, and the observation of economic fluctuations.

These advances do not, for Mises, imply that economics repeatedly destroys and replaces its foundations:

Kaum eine andere Wissenschaft weist eine ähnliche Kontinuität der Entwicklung auf wie die theoretische Nationalökonomie in den ungefähr 180 Jahren ihres Bestandes.

English translation: Hardly any other science exhibits a continuity of development similar to that of theoretical economics in the roughly 180 years of its existence.

Subjective value theory marks a profound break, but its problems and achievements remain connected to classical economics. Mises makes that continuity concrete by rejecting the attribution of purchasing-power parity theory to Cassel and himself. Both defended it, but he identifies it as an inherited classical doctrine and names Ricardo as the appropriate attribution. The passage combines a claim for theoretical progress with an explicit limit on claims of originality.

The culminating argument concerns the inadequacy of treating money as merely an outward modification of barter:

Das Wichtigste, was uns die Theorie des indirekten Tausches lehrt, ist das, daß die Vorstellung nicht zutrifft, man könne das Wesen aller Marktvorgänge durch eine Theorie des direkten Tausches erfassen, weil der Geldgebrauch nur die Form der Erscheinungen ändere, das Wesen aber unberührt lasse.

English translation: The most important thing the theory of indirect exchange teaches us is that the notion is untrue that one could grasp the essence of all market processes by means of a theory of direct exchange, on the ground that the use of money alters only the form of the phenomena but leaves their essence untouched.

Direct exchange remains a necessary initial abstraction, but it cannot explain complex market processes. Mises leaves open whether static theory can successfully be supplemented by a dynamic theory; he nevertheless insists that such an undertaking must begin with money and fiduciary media. Monetary economics thus becomes foundational to the study of economic change, rather than a specialized appendix to value theory.

The final paragraph extends this claim from explanation to the conditions of rational economic activity:

Nicht minder wichtig aber wurde uns die Erkenntnis, daß Wirtschaftsrechnung nur als Geldrechnung möglich und denkbar ist.

English translation: No less important, however, has become for us the insight that economic calculation is possible and conceivable only as monetary calculation.

Mises connects this proposition to the feasibility of socialism while stressing that its wider implications remain incompletely understood. The article’s significance lies in this compact enlargement of monetary theory’s scope: money matters not only for purchasing power and banking policy, but also for understanding market dynamics and the possibility of economic calculation.
