The vitality of Mises's private seminar, set against Wieser's dull lectures, opens this interview's return to interwar Vienna, where Machlup wrote his dissertation and argued monetary theory, business cycles, and method with Kaufmann, Schutz, and Feigl. Looking back from 1980, he redescribes Mises's a priori economics as a domain of construction—powerful for the pure logic of choice, useless for predicting a concrete steel price—and holds that economics is most fertile in negative predictions and least trustworthy in regression and macro-forecasting. He names methodological individualism and subjectivism as the enduring core of Austrian economics once marginalism became universal, concedes that liquidationist advice failed politically in 1933, and turns Hayek's account of the stable 1920s price level and unsustainable investment against Friedman's neglect of relative prices and costs.
I would say methodological individualism and subjectivism are the most important of the whole lot. Marginalism is internationally accepted. No one is an Austrian just because he is a marginalist.
