Comprehensive and authoritative, this book, written by a recognized authority on the subject explores the contributions to modern economics by John Maynard Keynes and addresses neglected, yet crucial aspects of the genesis of Keynesian economics.In this book, the author elucidates Keynes’ development as an economic theoretician through an examination of his books, articles, various manuscripts, lecture notes and controversial correspondence. Departing from a narrative account and analyzing processes of theory-building and re-building which constitute Keynes’s intellectual journey from the Tract to the General Theory, this volume shows Keynes’ theoretical development as a theoretical hypothesis.An excellent exposition of Keynes’ contribution, this is a valuable addition to the bookshelves of all to students and researchers interested in Keynes and more widely the history of economic thought and macroeconomics.
