Stimulus: A History of Folly:

"...in the new enthusiasm for stimulus, there is not a small degree of panic; monetary policy is not working, so fiscal policy must! To his credit, however, Feldstein writes toward the end of his January paper, “It is of course possible that the planned surge in government spending will fail. Two or three years from now we could be facing a level of unemployment that is higher than today and that shows no sign of coming down.”

The truth is that we have learned almost nothing about the use of fiscal stimulus since the Great Depression, and it is a fatal conceit to assume that we can hurriedly construct a fiscal policy that will produce the prescribed results today. Economists seem to admit this fact by advocating what they prefer anyway, for political or ideological reasons. I would feel better about stimulus if Elmendorf were clamoring for permanent tax cuts and Feldstein food stamps."
