Wilhelm Röpke: Review of Mentor Bouniatian’s Les crises économiques (1923)

Wilhelm Röpke’s journal book review assesses Bouniatian’s explanation of economic crises through three connected questions: what drives cyclical fluctuations, how their conceptual categories should be defined, and whether the contemporary world economic crisis belongs within a periodic cycle. His judgment combines appreciation of Bouniatian’s production-centred theory with objections concerning credit, demand elasticity, and the limits of cyclical explanation.

Röpke presents the French translation as a modernization and revision of Bouniatian’s earlier work. He praises its clear exposition, concise summaries, and improved organization. More substantively, he singles out three achievements: the application of marginal utility to general price changes, which he associates with Aftalion’s crisis theory; the systematic examination of structural features of the existing economic order that make cyclical movements intelligible; and the location of the ultimate cause of crises in production. In Bouniatian’s overcapitalization theory, an unrestricted tendency toward accumulation repeatedly collides with consumption’s limited capacity to expand.

Röpke nevertheless questions whether this explanation adequately recognizes a distinct financial mechanism:

Dabei ist allerdings die selbständige Konjunkturbedeutung des Kredits viel zu wenig beachtet.

English translation: Yet the independent significance of credit for cyclical fluctuations receives far too little attention.

His reference to Albert Hahn’s theory of bank credit makes the criticism specific: Bouniatian has left relevant monetary arguments entirely unconsidered. Röpke does not reject the production-side explanation outright; he challenges its sufficiency when credit is denied adequate independent explanatory weight.

The review then turns from causal mechanisms to conceptual precision. Bouniatian’s enlarged chapter on general price movements lacks an exact definition of economic fluctuations. For Röpke, whether fluctuations can simply be equated with price changes is a foundational question, yet the book addresses it only incidentally. He likewise accepts that differences among kinds of goods matter to the unfolding cycle, but disputes Bouniatian’s principle for ranking them:

Nicht der Grad der biologischen Unentbehrlichkeit eines Gutes entscheidet über seine konjunkturelle Bedeutung, sondern seine Bedarfselastizität, die viel kompliziertere Ursachen hat.

English translation: It is not the degree of a good’s biological indispensability that determines its significance for cyclical fluctuations, but its demand elasticity, which has much more complex causes.

This correction replaces a classification by necessity with an account of how demand responds. Röpke invokes his own Die Konjunktur in support, positioning the objection within an ongoing theoretical discussion rather than treating it as a merely terminological dispute.

The closing paragraph draws the review’s sharpest boundary. Bouniatian’s preface places the world economic crisis within the periodic business cycle; Röpke insists that war and the peace settlements require a different causal explanation:

Die Weltwirtschaftskrise ist vielmehr eine „exogene“ Krise allerersten Ranges. Sie beweist nichts über die Periodizität der Krisen.

English translation: The world economic crisis is, rather, an “exogenous” crisis of the first order. It proves nothing about the periodicity of crises.

The review thus moves from qualified endorsement to a restriction on the theory’s historical application. Its central contribution is to distinguish an explanation of recurrent economic mechanisms from an explanation of exceptional disruption: the devastation associated with war and peace cannot itself establish the periodic character of crises.
