Robert Barro Speaks out on the Current Stimulus
A couple of questions / answers ... click above to read the entire thing.
Do you read Paul Krugman's blog?
Just when he writes nasty individual comments that people forward... He just says whatever is convenient for his political argument. He doesn't behave like an economist. And the guy has never done any work in Keynesian macroeconomics, which I actually did. He has never even done any work on that. His work is in trade stuff. He did excellent work, but it has nothing to do with what he's writing about.
Are there any conditions under which you might think spending could have a positive effect on output or is it always going to be the case that as a relative matter that tax cuts are going to be better?
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. Even there I don't think it's one for one, so if you don't value the war itself it's not a good idea. You know, attacking Iran is a shovel-ready project. But I wouldn't recommend it.
