Don’t know what the reason for the quotes around the words “internationally known” in your earlier post. His name is Steven Levitt, and is described in wikipedia as follows: Winner of the 2004 John Bates Clark Medal, he is currently the William B. Ogden Distinguished Service Professor of Economics at the University of Chicago, director of the Becker Center on Chicago Price Theory at the University of Chicago Booth School of Business, and co-editor of the Journal of Political Economy published by the University of Chicago Press. He co-authored the best-selling book Freakonomics (2005) and its sequel Superfreakonomics (2009). Levitt was chosen as one of Time magazine’s “100 People Who Shape Our World” in 2006.[1]
What’s even more surprising is that he is in his early forties. He’s received a lot of attention for his work, even at U of C, where there is a (humorous) sign in the cafeteria indicating a special line for Nobel prize winners.
