A Conservative of Doubt

Greg Mankiw isn't sold on the rapidly expanding stimulus plans of the president-elect:

In general, I think economists need a large dose of humility when evaluating alternative proposals to deal with the current downturn, as there is still a lot we do not understand. I am sure I am not the only person in the economics profession skeptical of spending increases to stimulate the economy. See, for example, GMU economist Tyler Cowen. If the new administration wanted to find more skeptics of stimulus spending among professional economists, I could have come up with some possible candidates for them, but the Obama economists probably already know who those likely skeptics would be.
