This collection of Malcolm Sawyer's essays develops the post Keynesian analyses of unemployment, imperfect competition and macroeconomics. This important volume focuses on the causes of unemployment, a central concern of contemporary post Keynesian economics whose origins can be dated from the response to the high levels of unemployment during the 1930s. After explaining why conventional economic analysis cannot properly comprehend the phenomenon of unemployment, Professor Sawyer's book explores the relationship between demand-side and supply-side causes and argues for the relevance of both for the analysis of unemployment. Other issues discussed include the relationship between macroeconomics and imperfect competition, the post Keynesian approach to pricing and post Keynesian perspectives on industrial economics.Unemployment, Imperfect Competition and Macroeconomics, critically but sympathetically, evaluates and extends the contribution of post Keynesian analysis, and discusses the problems which those analyses face. Bringing together contributions from a major scholar working in this field, the book will be welcomed by all those interested in the post Keynesian approach and the contributions it can make to economic analysis.
