Karl Pribram, Gleichgewichtsvorstellungen in der Konjunkturtheorie (1937)

Karl Pribram’s journal article, based on a lecture delivered to the Vienna Economic Society in October 1936, examines equilibrium as the conceptual link between business-cycle theory, recovery policy, and statistical investigation. Its three sections successively classify theories, interpret policy disagreements, and propose a framework for clarifying statistical practice. Pribram’s central claim is methodological: explanations of economic fluctuations depend on how they define the economic system and the disturbances acting upon it. Equilibrium is therefore neither an exclusively mathematical device nor an innocent descriptive term.

Vor allem werden Krisen und Depressionen ganz allgemein als Störungen des Gleichgewichts der Wirtschaft aufgefaßt.

English translation: Above all, crises and depressions are quite generally understood as disturbances of the economy’s equilibrium.

Pribram finds this assumption embedded in ordinary explanations invoking overproduction, underconsumption, or excessive indebtedness, as well as in expectations that depression must eventually give way to recovery. Even proposed remedies presuppose some conception of the relationships to be restored. His criticism of historical, institutionalist, and organic approaches is that rejecting general equilibrium has not supplied an alternative method for explaining the general course of economic life.

Section I reconstructs the classical system as closed and universal: prices tend toward costs, competition coordinates supply and demand, and neutral money preserves the underlying relationships. Slow proportional expansion can convert static equilibrium into moving equilibrium without abandoning these premises. General crises, however, initially appear as exceptional disturbances originating outside the system. Pribram classifies subsequent cycle theories through two connected questions: what kind of system is assumed, and where, how continuously, and with what timing does the disturbing factor operate?

The first group, theories of independent variables, locates periodic impulses outside the economy, especially in natural events. The second admits intermittent internal impulses, such as technical innovation or entrepreneurial psychology. Here time becomes decisive: successive disturbances accumulate before compensating reactions can complete their work.

Unter diesem Gesichtspunkt sind Prosperität und Wirtschaftsaufschwung durch eine ständige Zunahme von Gleichgewichtsstörungen des Systems charakterisiert, während Krise und Depression den Anpassungsprozeß und die Herstellung einer neuen Gleichgewichtslage bedeuten.

English translation: From this standpoint, prosperity and economic expansion are characterized by a constant increase in disturbances of the system’s equilibrium, whereas crisis and depression signify the process of adjustment and the establishment of a new equilibrium position.

This reverses the intuitive identification of prosperity with balance: expansion generates disproportions, while depression corrects them. The third group instead assumes a continuously operating source of disequilibrium in distribution. Pribram associates this construction with Marxist surplus-value and imperialism theories, and more loosely with underconsumption theories. The fourth abandons classical monetary neutrality and distinguishes monetary relationships from relationships among material economic quantities. Credit-created purchasing power makes the monetary system “open,” allowing changes that disturb production and exchange. The fifth group explains particular cycles through changing combinations of causes and partial disturbances, without a clearly defined general system.

Section II concentrates on the fourth group’s division into monetary and structural schools. For the monetary school, expansion may approach equilibrium in material production and employment even while monetary disproportions develop. Credit contraction then destroys purchasing power and disrupts real activity; reflation and price stabilization promise restoration. For the structural school, apparently balanced production and sales conceal misdirected investment already generated during expansion. Recovery consequently requires cost reductions, investment write-offs, and painful production adjustments, rather than merely renewed purchasing power.

Pribram treats reflation, devaluation, gold-standard adherence, and deflation as expressions of these competing constructions. He also follows the fragmentation of the classical universal system into national economies and regulated individual markets. Exchange controls, compulsory cartels, agricultural regulation, wage policy, and bilateral clearing arrangements seek particular balances, but their objectives need not cohere.

Für alle derartigen Maßnahmen, deren Liste sich durch Aufzählung vieler anderer ergänzen ließe, ist es charakteristisch, daß sie regelmäßig jeden Zusammenhanges mit einer allgemeinen Gleichgewichtsvorstellung entbehren.

English translation: It is characteristic of all such measures, whose list could be supplemented by enumerating many others, that they generally lack any connection with a general conception of equilibrium.

The objection concerns coordination: policies securing one market’s balance can counteract general monetary policy or disrupt production elsewhere. National economic boundaries likewise raise an unresolved question—whether world fluctuations result from transmission between national systems or from forces operating globally.

Section III turns this conceptual analysis into a research programme. Pribram argues that statistical series cannot be selected and interpreted adequately without clarifying the system they describe. His questionnaire, developed with W. C. Mitchell and approved for circulation by the International Statistical Institute, asks about equilibrium’s meaning, the distinction and interaction between monetary and material systems, and international versus worldwide equilibrium. Possible indicators include cost-price relationships, saving and investment, income distribution, capacity utilization, and employment. Questions about timing and transmission connect these measures to rival causal accounts. The aim is not compulsory agreement on one theory, but intelligible differences that improve international comparison.

Pribram closes by acknowledging that equilibrium concepts remain vague and resist economic dynamics. A genuinely dynamic conception might transform economic thought, but it is not yet sufficiently developed for formal cycle theory.

Solange wir daher nicht über geeignetere Denkinstrumente verfügen, bleibt nichts übrig, als von den herkömmlichen, wenn auch einigermaßen unzulänglichen Hilfsmitteln unseres Denkens den bestmöglichen Gebrauch zu machen.

English translation: As long as we therefore lack more suitable conceptual tools, nothing remains but to make the best possible use of the traditional, albeit somewhat inadequate, aids to our thinking.

The article’s contribution is thus a disciplined clarification of working assumptions: equilibrium provides a common language for comparing explanations, exposing policy conflicts, and making statistical investigation theoretically accountable without claiming that its conceptual difficulties have been solved.
