This is a thoroughly updated and revised edition of the first, and definitive, biographical dictionary of dissenting economists. It is an extensive and authoritative guide to economists both past and present from Samir Amin to Ted Wheelwright, providing biographical, bibliographical and critical information on economists working in the non-neoclassical traditions broadly defined. It includes entries on, amongst others, radical economists, Marxists, post-Keynesians, behaviourists, Kaleckians and institutionalists. The book demonstrates the extent and richness of the radical heterodox tradition in economics.
