This volume of collected essays on Fisher,edited by Robert Dimand,establishes that he was in fact one of the greatest economists of the 20th century.What has hindered Fisher's historical reputation was the problematic,incorrect,notorious forecast he made in late 1929 that the stock market was on an upward path.The Great Crash of October,1929 cost him 11-12 million dollars in losses personally.His response to this catastrophe was to publish his debt-deflation theory of depressions which correctly points to the debt load in the economy as a whole as the best indicator of a possible depression resulting from some exogenous shock that starts the snowball rolling downhill.The excessive debt loads get worse as the price level falls.This leads to a first round of personal and business bankruptcies and home foreclosures .These bankruptcies force furthur rounds of bankruptcies as the debts of one individual were the assets of another.There is no substantial difference between Fisher's analysis and Keynes's General Theory conclusions.Unfortunately, Fisher's work was ignored in the rush to accept Keynes's work.This volume reestablishes Fisher's overall standing .It has great relevance today given the excessive debt loads that have again been created since 1981 in America.
