Presenting an in-depth overview of the foundations and developments of post-Keynesian macroeconomics since Kalecki and Keynes, this timely book develops a comprehensive post-Keynesian macroeconomic model with the respective macroeconomic policy mix for achieving non-inflationary full employment. The different versions of the model for closed and open economies are concerned with the key areas of macroeconomics, such as full employment, constant inflation and external balance. Eckhard Hein expertly illustrates how to embed these post-Keynesian macroeconomics and macroeconomic policies into the post-Keynesian research programme more generally, whilst also providing a review of its methods and historical roots. Furthermore, the book links post-Keynesian short-run macroeconomics to long-run distribution and growth theories. Finally, it applies these theoretical approaches to the current research on macroeconomic regimes and regime changes within finance-dominated capitalism and on the macroeconomic challenges of the ecological crisis and of the required socio-ecological transformation. This book will be a crucial read for academics and graduate students interested in post-Keynesian macroeconomics. Providing a thought-provoking alternative to orthodox economic policies, this will also be of interest to policy advisers and politicians.
