question:  What seems to be Krugman's biggest issue with Arthur?
context: Krugman's Life of Brian Where it all started: Paul Krugman's "The Legend of Arthur." 1) Krugman claims that my opening sentence--"In a way, Bill Gates's current troubles with the Justice Department grew out of an economics seminar that took place thirteen years ago, at Harvard's John F. Kennedy School of Government"--is "pure fiction." (As Krugman notes, one reason for this was technical, not ideological. 3) Pace Krugman, I also did not claim that Arthur bears principal responsibility for the rediscovery of increasing returns by economists in the 1970s and 1980s. As Krugman notes, several scholars (himself included) who were working in the fields of game theory and international trade published articles incorporating increasing returns before Arthur did. Krugman apart, virtually every economist I have spoken to, including Daniel Rubinfeld, a former Berkeley professor who is now the chief economist at the Justice Department's antitrust division, told me this was the case. 4) Krugman appears to suggest that I made up some quotes, a charge that, if it came from a more objective source, I would consider to be a serious matter. In effect, he is accusing Brian Arthur, a man he calls a "nice guy," of being a fabricator or a liar. Krugman, as he admits, wasn't present at either of the meetings. 5) For a man who takes his own cogitations extremely seriously, Krugman is remarkably cavalier about attributing motives and beliefs to others. To claim, as Krugman does, that I "don't like mainstream economists" and that I am out to denigrate their work is malicious hogwash. 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." Doubtless, this change in attitude on Krugman's part is unconnected to the fact that Arthur has started to receive some public recognition.
output:  Arthur received too much credit for increasing returns.
options:  Arthur allows too many people to misquote him.  Arthur received too much credit for increasing returns.  Arthur provided inaccurate information.  Arthur didn't do enough research on increasing returns.
