The New York Times bestselling Freakonomics was a worldwide sensation. Now, Steven D. Levitt and Stephen J. Dubner return with SuperFreakonomics, and fans and newcomers alike will find that the "freakquel" is even bolder, funnier, and more surprising than the first.

SuperFreakonomics challenges the way we think all over again, exploring the hidden side of everything with such questions as: How is a street prostitute like a department store Santa? Who adds more value: a pimp or a Realtor? What do hurricanes, heart attacks, and highway deaths have in common? Did TV cause a rise in crime? Can eating kangaroo meat save the planet?

Whether investigating a solution to global warming or explaining why the price of oral sex has fallen so drastically, Levitt and Dubner show the world for what it really is—good, bad, ugly, and, in the final analysis, superfreaky.

Steven D. Levitt, a professor of economics at the University of Chicago, was awarded the John Bates Clark Medal, given to the most influential American economist under forty. He is also a founder of The Greatest Good, which applies Freakonomics-style thinking to business and philanthropy.

Stephen J. Dubner, an award-winning journalist and radio and TV personality, has worked for the New York Times and published three non-Freakonomics books. He is the host of Freakonomics Radio and Tell Me Something I Don't Know.
