Included in this volume are papers which are recognized as some of the foundations of post-Keynesian Economics, analysing problems set in historical time and starting from 'real world' observations. The book reflects Geoff Harcourt's contribution to economic debate over more than three decades. It also includes intellectual biographies of some of the most prominent and leading unorthodox economists, such as Kenneth Boulding, Eric Russell and Lorie Tarshis.
