Host: Chris Mooney

We are thrilled by our guest this week, who is not only one of the world's most famous economists and economics commentators, but also a Nobel Laureate in his field: Paul Krugman.

In case he needs any introduction: He is a professor of economics at Princeton and a columnist for the New York Times, as well of the author of the blog on its website entitled "The Conscience of a Liberal."

The occasion for our interview is the release of his latest book, End this Depression Now, in paperback. It is just out and, besides being a very lucid explanation of our current economic predicament, it is also a work that goes straight at the heart of a central concern of this show—what is science, and what isn't, in a field that is perhaps even more political than other aspects of science... economics.
