Economic methodologists have traditionally paid very little attention to heterodox economic theories. In this major new book three leading heterodox scholars respond to the influential appraisals of Sraffian, Radical and Marxian economics made by Mark Blaug, the eminent economic methodologist. Heterodox Economic Theories begins with a paper by Ian Steedman on Sraffian economics and the capital controversy. This is followed by papers on radical economics by Michael Reich and Marx's economic analysis by Fred Moseley. Professor Moseley has also written an extensive introduction to the work featured in this volume. Including replies by Mark Blaug and comments by a distinguished group of economic methodologists, this book offers a stimulating debate between heterodox and mainstream economists over the value of three important economic traditions and over the most appropriate methodology for the appraisal of economic theories.
