World War I ended in 1918. From at least as early as 1919 to 1932, Keynes kept criticizing the Allies’ reparations policy towards defeated Germany. In the debate he initiated, the most powerful idea that Keynes resorted to was the concept of the transfer problem. This article reviews Keynes’s transfer problem and the recent amendment to Keynes’s point of view. Since the transfer problem was part of Keynes’s plan for European debt restructuring, this article also discusses Keynes’s proposals for dealing with interally war debts and his conflict of interest during the debate.
