 Where was John Cassidy’s piece published?
I am reluctant to dignify his hatchet job with a lengthy reply, but some of his claims are so defamatory that they should be addressed, if only for the record. Perhaps so, but in that case somebody should tell this to Joel Klein, the assistant attorney general in charge of the antitrust division. I presume this statement refers to a critical piece I wrote in 1996 about the direction that economic research, principally macroeconomic research, has taken over the past two decades. Evidently, Krugman felt four years ago that Arthur's contribution was important enough to merit a prominent mention in his book. Now, he dismisses the same work, saying it "didn't tell me anything that I didn't already know."
