John Maynard Keynes never ceases to fascinate macroeconomists, whether they see themselves as his disciples, as his opponents, or as eclectics drawing insight both from him and from earlier competing or complementary traditions. Keynes raised a number of important questions -- about the stability of the economy, the economic role of government, the proper institutional framework of the world economy, the relation of economic decisions to an uncertain future -- these questions remain as vital today as when he posed them. This volume brings together Keynesian scholars and leading macroeconomists from around the world to commemorate the seventieth anniversary of the publication of The General Theory of Employment, Interest and Money and to reflect upon Keynes's impact as a public intellectual. It provides a comprehensive overview of Keynes' contributions to macroeconomics and offers an in-depth analysis of the contested legacy of The General Theory, a book that marked the emergence of modern macroeconomics from the earlier heritage of monetary theory and business cycle and analysis. This book will be indispensable reading for all interested in Keynesian economics and macroeconomics.
