Roland Fryer and I have done some research on this topic which we think is potentially quite interesting and important — although we seem to be the only ones with this opinion at present. (The paper was rejected yesterday by the American Economic Review on the second round of review, and a search of Google Scholar reveals only two citations to the working paper version released in early 2006.)

Controvesial.
