here for a good WSJ appreciation of Krugman's Nobel. I have "Pop Internationalism" and intend on re-reading it. Yes, long ago, he did some ground breaking work concerning trade and how some countries grow and how trade makes that possible.
That said, how can he so persuasively argue for free trade and write some of the most partisan columns and support an anti-trade Democrat platform? He is not a "hack" economist, but he is a "hack" political writer. And one can be both.
