A passionate theorist and socialist, Joan Robinson made major contributions to the field of economics during her lifetime. Active in the profession for fifty years, she worked through a number of major upheavals to the received orthodoxy of economics and, in many cases, was at the forefront of the controversies. Her style was provocative and challenged the leaders in the field. This collection gathers together outstanding material which not only illustrates Robinson's intellectual path but, in doing so, documents the major debates in economic theory.
