I must say, I'm not particularly enjoying this Sitglitz-Krugman pattern in the prizes, but when Krugman stops his anti-Bushism, he's a very good economist and he's no protectionist. Krugman also has the rare privilage of having a permenent link from my blog, on a list which is otherwise dominated by libertarians or classical liberals. As you can see, I read the right people.
So far, the best synopsis is from Tyler Cowen. More to come I'm sure.
