Robert Barro on Paul Krugman

He said elsewhere that it was good and that it was what got us out of the depression. 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.

I guess Barro would rather speak his mind than kiss up for a possible Nobel. Good for him.

Here's another zinger:

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.
