Marschak’s later attempts to clarify the concept of liquidity and to emphasize the role of new information for economic behavior date back as far as to his early experiences with hyperinflationary processes in the Northern Caucasus during the Russian Revolution. Marschak came to monetary theory with his 1922 Heidelberg doctoral dissertation on the quantity theory equation of exchange (published in 1924 as “Die Verkehrsgleichung”), and embedded monetary theory in a wider theory of asset market equilibrium in studies of “Money and the Theory of Assets” (1938), “Assets, Prices, and Monetary Theory” (with Helen Makower, 1938), “ Role of Liquidity under Complete and Incomplete Information” (1949), “The Rationale of the Demand for Money and of ‘Money Illusion’” (1950), and “Monnaie et liquidité dans les modèles macroéconomiques et microéconomiques” (1955), as well as in Income, Employment and the Price Level (lectures Marschak gave at Chicago, edited by Fand and Markowitz, 1951). Using both Marschak’s publications and unpublished archival material, we examine Marschak’s analysis of money within a broader theory of asset market equilibrium and explore the relation of his work to the monetary and portfolio theories of his doctoral students Markowitz and Patinkin and his colleague Tobin and to the revival of the quantity theory of money by Milton Friedman, a University of Chicago colleague unsympathetic to the methodology of the Cowles Commission.
