David Autor and the polarization of labor market outcomes

I was just going to write a post about David Autor as the "weighted average of most important yet most neglected economist for the blogosphere," or something like that.  Yet Paul Krugman just did essentially that.  In my view it is one of Krugman's best posts.

This may sound strange, but to think through these issues I spend some time playing chess against a computer, and also allied with a computer.  It beats me, but I learn a lot from the experience and I'll be reporting on that.  

By the way, there is quite a bit from Autor which Krugman didn't cover, you can pursue the material here on Autor's home page, start with the May 2010 CAP paper as the most accessible introduction.
