Abstract
According to Leijonhufvud, the development of economic theory can be compared to a decision tree, the branches of which originate in choices made about basic methodological nodes. My paper is an attempt at putting this insight into practice by reconstructing the recent history of macroeconomics on its basis. To this end, I examine whether the decision-tree framework can explain three crucial turns in the history of the field: (a) the transition from Keynesian to new classical macroeconomics triggered by Lucas; (b) the transition from the Lucas model to Kydland and Prescott’s ‘real business cycle’ modeling strategy; and (c) the transition from RBC modeling to DSGE modeling.
