Alan Schwartz reports for the New York Times:
A coming paper by a University of Pennsylvania professor and a Cornell University graduate student says that, during the 13 seasons from 1991 through 2004, white referees called fouls at a greater rate against black players than against white players.
Interesting. Tyler Cowen observes that "The effect is big enough that an all-white team would, all other things equal, win two extra games over the course of an 82-game season." Of course, all other things are unlikely to be equal if you try and field an all-white team. Which, of course, leads to the ever popular question of who makes the All-White Team. My ballot has Okur at center, David Lee and Dirk Nowitzki at the forwards, and Nash and Ginobili in the backcourt.
