A History of Macroeconomics from Keynes to Lucas and Beyond

This book retraces the history of macroeconomics from Keynes's General Theory to the present. Central to it is the contrast between a Keynesian era and a Lucasian - or dynamic stochastic general equilibrium (DSGE) - era, each ruled by distinct methodological standards. In the Keynesian era, the book studies the following theories: Keynesian macroeconomics, monetarism, disequilibrium macroeconomics (Patinkin, Leijongufvud and Clower), non-Walrasian equilibrium models, and first-generation new Keynesian models. Three stages are identified in the DSGE era: new classical macroeconomics (Lucas), RBC modelling, and second-generation new Keynesian modeling. The book also examines a few selected works aimed at presenting alternatives to Lucasian macroeconomics. While not eschewing analytical content, Michel De Vroey focuses on substantive assessments, and the models studied are presented in a pedagogical and vivid yet critical way.

'Michel De Vroey does not simply record what he finds. He has a vision of the kind of macroeconomics he would like to see, perhaps one he developed gradually over the years he has worked on this book. What makes this book enjoyable is that he has high hopes for economics, he flatters us that we are important, and he praises the progress we have achieved. In the end he has the integrity not to hide his disappointments, his conviction that while there is no turning back, there is still a long way to go.' Robert E. Lucas, Jr, John Dewey Distinguished Service Professor in Economics, University of Chicago
