Friedrich A. von Hayek, “Der Stand und die nächste Zukunft der Konjunkturforschung” (1933)

Hayek’s 1933 Festschrift essay is a compact methodological and theoretical stocktaking of business-cycle research. Its opening move is to resist any identification of “Konjunkturforschung” with the mere collection of contemporary statistical material. For Hayek, the state of the field is measured by causal insight: facts matter as the testing ground of theory, not as a substitute for it.

Wie immer man »Konjunkturforschung« definieren mag, so kann doch kein Zweifel darüber bestehen, daß sowohl der gegenwärtige Stand als auch Aussichten und Aufgaben der nächsten Entwicklung am besten durch das Ausmaß unserer Einsicht in die Ursachenzusammenhänge des untersuchten Gebietes charakterisiert werden und nicht durch die Menge des zur Zeit verfügbaren Tatsachenmaterials, das doch nur das ständig wechselnde Objekt darstellt, an dem wir diese Einsicht zu erproben haben.

English translation: However one may define 'business-cycle research,' there can be no doubt that both its present state and the prospects and tasks of its future development are best characterized by the extent of our insight into the causal connections of the field investigated, and not by the quantity of factual material currently available, which after all represents only the ever-changing object against which we must test that insight.

The essay’s central judgment is that crisis theory has advanced further than depression theory. Hayek identifies a convergence among Wicksellian, Misesian, Spiethoffian, and related lines of analysis: credit expansion can lengthen and distort the structure of production when investment plans are not matched by voluntary saving. The resulting crisis is not simply a shortage of capital in a crude aggregate sense, but a contradiction within the intertemporal pattern of production and consumption.

Der wichtigste Fortschritt im einzelnen ist hier zweifellos die genauere Analyse dieses mit „Kapitalmangel“ (oder „Mangel an umlaufendem Kapital“) sicher unzureichend beschriebenen Zustandes von „Mangel und Überfluß zugleich“ (Spiethoff)², die zum Durchdringen der Einsicht geführt hat, daß dieser Kapitalmangel mit relativem Überkonsum identisch ist.

English translation: The most important advance in detail is here without doubt the more precise analysis of that state of 'scarcity and superabundance at one and the same time' (Spiethoff)², which is surely inadequately described as 'capital shortage' (or 'shortage of circulating capital'), an analysis which has led to the acceptance of the insight that this capital shortage is identical with relative overconsumption.

This diagnosis lets Hayek reject underconsumption explanations while restoring the rate of interest to its coordinating role between present and future uses of resources. Yet he also emphasizes how much remains unresolved in capital theory itself. Maintenance, transformation, and consumption of capital in a dynamic economy cannot be handled by simple aggregates. The recent failure of price-level stabilization to prevent crisis reinforces his point: monetary analysis must attend to relative prices and the structure of production, not only to the general price level.

The most forward-looking part of the essay turns from the cause of crisis to the process of depression. Once a boom has produced an untenable expansion of the capital structure, recovery requires real revaluation and reallocation. Inventories, production plans, relative prices, and the direction of productive resources must all change.

Daß, wenn eine übermäßige Erweiterung der Kapitalstruktur sich als unhaltbar erwiesen hat und zur Krise führt, zur Wiederherstellung der Rentabilität beträchtliche relative Preisänderungen, Abbau gewisser Vorräte⁶ und Umleitungen von Produktionsmitteln erforderlich sind, ergibt sich aus der Analyse der Krise.

English translation: That, once an excessive expansion of the capital structure has proved untenable and led to crisis, considerable relative price changes, a running-down of certain stocks⁶, and redirections of means of production are required to restore profitability, follows from the analysis of the crisis.

Hayek therefore treats price and wage rigidity as central to the unfinished theory of depression. He neither presents deflation as automatically curative nor condemns every fall in prices as destructive. The problem is to distinguish those price movements that help undo prior maladjustments from those secondary deflationary processes that continue after their original coordinating function has disappeared. Expectations, cash balances, velocity, and intertemporal relative prices thus become indispensable topics for the next phase of research.

The essay’s broader ambition is integrative. Hayek wants business-cycle theory to connect monetary theory, capital theory, and general price theory. Anticipated future price movements can alter the relative attractiveness of present consumption-goods production and investment for future output; changes in money holding and credit use can disturb or restore intertemporal coordination. Depression and recovery cannot be understood by isolating “money,” “capital,” and “prices” into separate analytical compartments.

In its closing movement, Hayek considers revival under conditions of unemployment and idle capacity. Credit expansion remains inflationary in principle, but its effects differ when unused labor and capital are available. It may raise consumer-goods demand before output adjusts, alter real wages, and interact with wage rigidity in ways not captured by a full-employment model. He also allows exceptional cases in which voluntary saving may absorb capital first brought into existence through forced saving.
