President Obamas stimulus plan has not produced the announced reduction in unemployment. The reason for this failure is that the Keynesian multiplier is less than one. Other countries - France is an exemple - have ignored this fact. They have launched stimulus plans of their own supposed to save jobs. However, the cost of these plans and the increases in public debt they entail are ignored.
