Karl Pribram, Die Idee des Gleichgewichtes in der älteren nationalökonomischen Theorie (1908)

Pribram traces equilibrium as an organizing idea of economics from mercantilism through physiocracy to Adam Smith. His central argument is that economic liberalism changed the units to which equilibrium applied without abandoning its mechanistic foundations. Economic doctrines emerge through their relationships to natural science, natural law, and political power.

The opening locates the formation of scientific theory in generalizing abstraction. An observation established within a limited field becomes a principle extending beyond its original evidence:

So wird zunächst eine für eine bestimmte Erscheinungsgruppe gewonnene Beobachtung durch Verallgemeinerung zum Range eines Gesetzes, einer das ganze Naturgeschehen beherrschenden Regelmäßigkeit erhoben.

English translation: Thus an observation obtained for a particular group of phenomena is first raised, by generalization, to the rank of a law, of a regularity governing the whole course of nature.

Such generalizations can persist despite their inadequacies. Economics borrowed from mechanics the expectation that opposing forces must balance. Yet its earliest applications concerned collective quantities rather than relations among individual economic actors:

Freilich, nicht für die Auffassung der gegenseitigen Beziehungen der Einzelwirtschaften wurde dieser Gedanke zunächst von Bedeutung.

English translation: To be sure, it was not for the conception of the mutual relations of individual economies that this idea first became significant.

This distinction structures the genealogy. Mercantilist reasoning sought equilibrium between national aggregates when commerce was closely bound to state power. Pribram emphasizes the importance of international exchange:

Von größter Bedeutung für die wirtschaftliche Entwicklung dieser Staaten war ihr Anteil am Außenhandel, vor allem an der Vermittlung des Verkehres zwischen den europäischen Ländern und den neuentdeckten Kolonialgebieten.

English translation: Of the greatest importance for the economic development of these states was their share in foreign trade, above all in the mediation of the traffic between the European countries and the newly discovered colonial territories.

Commercial rivalry connected the balance of trade to Europe’s political balance. One nation’s gain appeared as another’s loss, and precious-metal inflows indicated relative strength. Pribram nevertheless rejects a blanket identification of mercantilism with the belief that gold alone constituted wealth. Bullion mattered because its international purchasing power represented command over other goods. Mercantilist writers shared less a single policy prescription than a method of balancing collective economic phenomena.

Quantity theories of money extended this method by relating national stocks of goods and money before deriving particular prices. Qualifications concerning circulation, expenditure, and exchange rates refined the aggregate framework without displacing it. Even criticism of protection could retain its premise: Hume’s account of money seeking its level made equilibrium a mechanism frustrating permanent commercial superiority, rather than a condition maintained through intervention. Domestic analysis similarly balanced producers against consumers, agriculture against manufactures, and population against subsistence.

The decisive transition was from collective entities to individuals. Natural-rights thinking, especially Locke’s, helped establish the individual as the starting point of political explanation. Economics shifted toward particular exchanges and toward labor, production costs, or land as objective determinants of value. This individualism remained mechanistic, however. Freedom from regulation required an additional assumption: that individual conduct and collective welfare would harmonize.

Pribram assigns Shaftesbury’s rehabilitation of self-interest an important role in this development. Order increasingly appeared inherent in human nature rather than dependent upon administrative direction. Historically oriented alternatives in Hume, Montesquieu, Ferguson, and Steuart did not decisively overturn the dominant framework.

Physiocracy systematized natural order and understood wealth as consumable goods continually reproduced, sharpening the problem of distribution. Yet its treatment of exchange as an exchange of equivalents and its restriction of net product to agriculture preserved restrictive balancing constructions. Pribram contrasts these with subjective approaches to value in Galiani, Turgot, and Condillac, whose development he regards as obstructed by materialist assumptions and Smith’s subsequent authority.

Smith completes the main trajectory. Annual production serves individual needs, while competition coordinates private interests through adjustments in prices, wages, and profits. Pribram scrutinizes the assumptions sustaining this harmony, including individual economic similarity, mobility of labor and capital, and abstraction from unequal bargaining power. Smith recognizes counteracting circumstances, but equilibrium remains an organizing expectation.

The conclusion extends the genealogy to nineteenth-century socialism, where evolutionary thinking relocates equilibrium from simultaneous economic relations to historical succession. Pribram thus reveals conceptual continuity across opposed political programs: intervention and laissez-faire could both invoke equilibrium, depending on the entities being balanced and the mechanism presumed to reconcile them.
