Krugman vs. Levitt

Krugman's theory of interstellar trade has just been published, 32 years after it's been written. Levitt saw it as a perfect opportunity to diss Krugman in public:

I did not think that Paul Krugman was still writing academic papers. Nor have I seen any evidence in the last decade that he still has any sense of humor... A quick look at the acknowledgments, however, clears things up. The original manuscript was written in July 1978, when Krugman was an active researcher and being a curmudgeon wasn’t part of his professional identity.

Wow! While some actually take the time to actually criticize the paper, this was one cheap shot by a brilliant pop economist on another. Chicago will always be Chicago I guess...
