Economists shave hairs on whether basketball games are fixed: Any bets on who wins?

In my March 26 blog I reported that 'forensic economist' Justin Wolfers, a professor at the University of Pennsylvania, inferred point-shaving from his statistical analysis of 44,120 NCAA Division I basketball games between 1989 and 2005. This new study by University of Illinois economist Dan Bernhardt disputes Wolfer's contention that statistics indicate point-shaving on college basketball. Perhaps it's only natural that superior teams fall short of expectations on their winning margin. According to Professor Bernhardt "the statistical properties that Wolfers identified in his paper seem to be intrinsic to the game of basketball itself, occurring independently of whether there are incentives to point shave, and are not indicative of an epidemic of gambling-related corruption."
It's good that this new analysis dissipates the cloud of suspicion about point-shaving raised by the first study.
