Students in economics are ever more distressed by the disconnect between mainstream economics and the real world. This book shows how post-Keynesian economics constitutes a coherent heterodox alternative, based on realistic assumptions and the integration of the financial and real sides of the economy, with an emphasis on the many paradoxes that arise in a truly macroeconomic analysis.The book is a considerably revised and updated version of the widely used and frequently cited 2014 edition. It provides a comprehensive account of post-Keynesian theory and policy. Topics covered include its methodological foundations, consumer theory and choice under fundamental uncertainty, firms and pricing, money and credit, effective demand and employment, growth theory, open-economy issues, inflation theory. It also links with ecological economics. Scholars of economics, particularly post-Keynesian and heterodox economists, will find this comprehensive look at the field a necessary addition to their libraries, while students and instructors will find it a perfect text for any class on post-Keynesian economics.
