Others say that we should have a fiscal stimulus to “give people confidence,” even if we have neither theory nor evidence that it will work. This astonishingly paternalistic argument was tried once with the TARP. Nobody could say how it would work in any way that made sense, but it was supposed to be important do to something grand to give people “confidence.” You see how that worked out. Public prayer would work better and cost a lot less. Seriously, as social scientists, economists don’t have any special expertise to prescribe what intrinsically meaningless gestures will and will not give “confidence,” so there is no reason for anyone to listen to our opinions on that score.
