Steven Levitt is a Harvard-educated economist at the University of Chicago. This guy studied the economics of pretty much everything.

One such experiment was the study of the economics associated with horse racing. Levitt borrow thousands of dollars and gambled it on races to study the economics involved. Since then Levitt has followed Sumo wrestling and other professional sports.

One thing he is infamous for is it theory about abortion. He believes that the recent lack of crime has not been due to our ecomonic stability. He links our progress to the legalization of abortion. With abortion legalized, fewer "unwanted" people are walking around causing trouble.
