Frank Knight joined the University of Chicago economics department in 1929, bringing a perspective that would shape the school's early identity. His 1921 book Risk, Uncertainty and Profit introduced the concept of Knightian uncertainty, distinguishing between measurable risk and true unpredictability. This distinction became foundational for later thinkers who questioned standard economic models. Henry Simons arrived at the university in summer 1927, even before Knight did, and developed antitrust and monetarist models during his long tenure. Jacob Viner taught at Chicago for thirty years from 1916 to 1946, inspiring generations including Milton Friedman with his focus on incentives rather than general equilibrium. These scholars formed what historians now call the Old Chicago school, operating during the 1920s and 1930s when Keynesianism had not yet dominated American economics. Their work emphasized price theory and the complexity of economic events over broad macroeconomic aggregates. The group included Aaron Director, who later founded law and economics, and Lloyd Mints, whose monetary theories influenced future policy debates. While their approaches varied, they shared skepticism about government efficiency and belief in market mechanisms.
The Friedman Revolution
Milton Friedman received the Nobel Prize in Economics in 1976 for his work on consumption analysis, monetary history, and stabilization policy. He argued that the Great Depression resulted from Federal Reserve policies during the 1920s and worsened through the 1930s. His 1963 book A Monetary History of the United States became a landmark text challenging Keynesian dominance. Friedman advocated gradual expansion of the money supply as neutral monetary policy oriented toward long-run growth. He believed active fiscal or monetary interventions often produced unintended negative consequences. In Capitalism and Freedom, published in 1992, he wrote that governments should avoid interventionist policies whenever possible. His slogan money matters encapsulated his quantity theory of money, which held that general prices are determined by money supply levels. Critics like Thorstein Veblen had previously modeled people as lightning calculators of pleasure and pain, but Friedman pushed back against such characterizations while maintaining rigorous analytical standards. George Stigler tutored under Frank Knight and won the Nobel Prize in 1982 for studies of industrial structures and public regulation. Their combined influence transformed macroeconomic thinking away from Keynesian frameworks toward monetarist approaches throughout the mid-20th century.
