Mises and Hayek Dehomogenized

Mises and Hayek Dehomogenized is Joseph T. Salerno’s 1993 Review of Austrian Economics paper arguing that Mises and Hayek should not be treated as interchangeable representatives of a single Austrian paradigm.

The Dehomogenization Claim

Salerno adapts William Jaffe’s “dehomogenization” move in the history of marginalism. Just as Menger, Jevons, and Walras founded different marginalist traditions, Salerno argues that modern Austrian economics inherited two different paradigms from Menger’s students and successors.

The Mises paradigm develops the Bohm-Bawerk-Mises-Rothbard line. The Hayek paradigm develops the Wieser-Hayek-Kirzner line. Salerno does not deny overlap, shared Austrian ancestry, or the quality of Hayekian work. His objection is to reading Mises through Hayekian categories and then treating the result as the Austrian position.

Equilibrium and Market Process

For Salerno, the Misesian market process is built around purposeful choice, monetary calculation, realized prices, and entrepreneurial appraisement under uncertainty. Equilibrium constructs such as the final state of rest are analytical devices, not states toward which history reliably moves in calendar time.

The Hayek-Kirzner paradigm, on Salerno’s reading, treats the market more directly as a coordinating and discovery process. It emphasizes ignorance, alertness, dispersed knowledge, and the tendency toward plan coordination. Salerno argues that this shifts the center of analysis away from Mises’s calculation-based theory of action and entrepreneurship.

Socialist Calculation Debate

The sharpest difference appears in the socialist-calculation debate. Mises’s argument is an impossibility claim about monetary calculation: without private ownership and exchange of higher-order goods, there are no genuine factor prices, and rational economic calculation becomes impossible.

Hayek’s argument, as Salerno presents it, is an impossibility claim about centralized knowledge: planners cannot gather and use the dispersed, tacit, local information that market prices communicate. Salerno treats both as anti-socialist arguments, but not as the same argument. The Misesian defect is absence of calculable market prices; the Hayekian defect is absence of usable dispersed knowledge.

Why It Matters

The paper matters because it sorts later Austrian debates about entrepreneurship, equilibrium, free banking, monetary theory, and calculation. It also clarifies why Salerno identifies himself with the Mises-Rothbard paradigm. It is a map for reading Ludwig von Mises, F. A. Hayek, Joseph T. Salerno, and the calculation-problem articles without flattening their differences.

The article’s confidence is high as a report of Salerno’s own argument. Its broader historiographical thesis remains an interpretive position within Austrian economics rather than a neutral taxonomy accepted by every Austrian writer.
