This updated edition takes account of new materials and new scholarship on Keynes that have appeared since 1980. It analyzes Keynes' intellectual origins and characteristic modes of thought so as to put Keynes' contributions to economics, economic policy-making and wider aspects of British life into perspective. D.E. Moggridge traces the emergence and impact of Keynes' works: The Economic Consequences of Monetary Reform, A Treatise on Money Probability and The General Theory. Moggridge is the joint managing editor of The Collected Writings of John Maynard Keynes and author of The Return to Gold 1925 and British Monetary Policy 1924-1931.
