Marx’s influence extends well beyond the self-identified Marxian school to several other important heterodox traditions within economics, though this often passes unrecognised on both sides. Consequently, the proper boundaries of the Marxian school of economics are much wider than either many self-identified Marxists, or indeed crypto-Marxists, generally consider. Each of the Minskian, post-Keynesian, Sraffian, institutional, feminist and social ecological (dominant) schools/branches of heterodox economics make a significant contribution in developing effectively Marxist themes and theory. Self-identified Marxists, as well as crypto-Marxists, stand to benefit intellectually and practically from a mutual recognition of this implicit division of hererodox economics labour.
