Paul Krugman has a sharp pen. Here he is on Eugene Fama's piece I posted earlier. And here he is again, this time on Robert Barro's take on the stimulus plan.
Obviously, comments like these don't go unanswered. Here's Fama, and here is Barro (in a rather terrible interview, who is this interviewer?!).

Btw, the Krugman blog for the NY Times usually makes for a very interesting read. And sometimes he even quotes investment bankers...
