I know, I know - I need to be more specific with a title like that!
She weighs in on the MR/Krugman spat. I found this pretty funny though: "I will note that the commenters Paul Krugman sends to other sites harbor a very strange faith in his predictive powers"
"Sends to other sites"??? What a bizarre thing to say! I love how people act like those of us who are positively disposed towards Krugman and DeLong are somehow enthralled to them. It couldn't possibly be that we're convinced by them or just think they have good points to make. No! They "send us to other sites".
One thing you won't here me talking about much on here is "predictive powers" of Paul Krugman or anyone else. That should not be surprising, since I've long noted the problems associated with forecasting complex systems. What we need is explanatory power, not predictive power - and Paul Krugman does actually do pretty well in that regard. I don't know his "predictions" in any great detail - but if they're right I think that has more to do with (1.) luck, or (2.) stating the obvious than any great skill in economics.
