This research review offers an examination and discussion of the seminal contributions by many prominent scholars in the heterodox tradition of post-Keynesian economic thought. The authors explore methodological issues - showing the contrast with orthodox thinking on fundamental grounds, concepts such as credit, money and production - which are crucial to understanding the working of our economic systems, as well as several interrelated macroeconomic issues including employment, distribution, growth, development, asset bubbles, and financial crises. The review provides a unique opportunity to appraise and appreciate the depth and variety of post-Keynesian economics at both theoretical and policy-oriented level.
