ABOUT THE SPEAKER
Steven Levitt - EconomistSteven Levitt's eye-opening Freakonomics took economic theory into the real world of suburban parenting and urban drug gangs, turning conventional wisdom upside-down.
Why you should listen
With his 2005 book Freakonomics (co-authored with Stephen Dubner, a writer who profiled him for the New York Times), Steven Levitt carried hardcore economic method into the squishy real world and produced a pop-culture classic. Freakonomics is both an economics textbook and a series of cautionary tales about the fallacy of conventional wisdom. Levitt examines the links between real-world events, and finds many instances where the data simply doesn't back up popular belief.
He asks provocative questions: If selling crack is so lucrative, why do dealers live with their mothers? Does parental doting really improve children's test scores? Did New York City's crime rate really drop because of police tactics (or population trends)? His controversial answers stir debate, and sometimes backlash.
