Harvard’s Robert Barro interviewed about Keynesian spending, tax cuts, Paul Krugman, and. . .
Tax cuts are bound to be better. I think the best evidence for expanding GDP comes from the temporary military spending that usually accompanies wars — wars that don’t destroy a lot of stuff, at least in the US experience.
