Way back when I said it wouldn't be a very worthwhile debate. There was a lot of really bad Austrian commentary on Keynesianism at the time, I wasn't familiar with Bob, and I hadn't had the chance of stumbling on any discussion of Bob's that made me think it would be an interesting debate.
My view on that has changed over the almost two years since I wrote that post. Bob is a sharp guy and a fair guy, and this would be a debate worth seeing. To press the issue, up-vote this comment on reddit, and share the link.
In a lot of ways Bob will have a big advantage - I think he's probably more familiar with Krugman's position than vice versa (something I am not willing to concede for a lot of major Austrians or Austrian-fellow-travelers that have made a big splash in various social media).
I think Krugman is right on almost all points, obviously. And the guy is not some pundit or partisan as many suggest. He's a brilliant economist with a real talent for communicating what he knows.
So I'll be rooting for Krugman - but this will be a good debate to see nonetheless.
UPDATE: There's not a shortage of good questions/comments for Krugman. Could you imagine Friedman alive and maintaining a blog through this crisis? How amazing would that be?
