James Joyner of Outside the Beltway provides a nice discussion here.
I also just found out that Susan Fleck will be my professor for Gender Economics this fall. She is a guest professor, so of course the first thing I did was familiarize myself with some work she's done. And lo and behold, she also has some recent work in the Monthly Labor Review on the divergence of productivity and compensation. I have not had the chance to read it yet.
Noah Smith's comment section has also grown and has a lot of discussion worth reviewing if you're intereste in this..
