LARGE PRINT EDITION More at LargePrintLiberty.com. This collection of articles on the business cycle, money, and exchange rates by Ludwig von Mises appeared between 1919 and 1946. Here we have the evidence that the master economist foresaw and warned against the breakdown of the German mark, as well as the market crash of 1929 and the depression that followed. He presents his business cycle theory in its most elaborate form, applies it to the prevailing conditions, and discusses the policies that governments undertake that make recessions worse. He recommends a path for monetary reform that would eliminate business cycles as we have known them, and provide the basis for a sustainable prosperity.
