 Who seems to be writing the most falsehoods?
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. It was Klein's words, not those of Arthur, that prompted me to use Arthur in the lead of the story. I wrote no such thing, and Arthur has never, to my knowledge, claimed any such thing. In effect, he is accusing Brian Arthur, a man he calls a "nice guy," of being a fabricator or a liar. The quotes in question came from Arthur, and they were based on his recollections of two meetings that he attended some years ago. The fact of the matter is that I spend much of my life reading the work of mainstream economists, speaking to them, and trying to find something they have written that might interest the general public. What Paul David, Brian Arthur, and a growing number of other economists began to realize in the late seventies and early eighties was that stories like that of the typewriter keyboard are, in fact, pervasive in the economy." 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." As a professional journalist, I found his points well taken--even when he cites my own book, Complexity as a classic example of the gullibility genre.
