Ok, so it's not a blog, but Krugman has been posting on TPM Cafe. Alas, the "posts by" page does not itself have a feed.
... Anyone who thinks that neoclassical economics says that everyone gains from free trade, and that you have to reject the assumptions of the field to raise concerns, obviously doesn't know anything about the subject: ever since Stolper-Samuelson 1941 we've known that trade can easily hurt large numbers of people, so the question is always an empirical one. A dozen years ago I thought the effects were small, but that was based on the numbers, not a judgment in principle. Now I've revised my views up, because the numbers are bigger...I haven't read that anywhere else, and I pay attention to this stuff (layperson attention of course, I'm not an economist). Stolper-Samuelson, eh?
I suspect Krugman's NYT contract may limit what he can do, but this is good stuff all the same. I hope the TPM Cafe people are thinking about how to add a feed to user post history ...
