NRO has posted an article I wrote about him back in 2001.
Krugman can be interesting when he is not writing polemics against imaginary adversaries. In his first months at the Times, this was frequently the case. He criticized the campaign to break up Microsoft on the grounds that standard neoclassical analysis, which counsels against a breakup in such a case, should trump any speculation about the effect of a breakup on technological innovation. He suggested that Alan Greenspan is not an infallible source of wisdom on public policy, and should be careful not to imply that he is. He pointed out that the fuss over bioengineered foods was out of all proportion to the health risks they pose, which are far lower than those associated with diet supplements.
But then came the presidential election. . . .
