Speaker: Stephen J Dubner, Professor Steven D Levitt This event was recorded on 9 November 2009 in Peacock Theatre, Portugal Street Freakonomics was a worldwide sensation, selling 4 million copies in 35 languages. Now, four years in the making, arrives the follow up: SuperFreakonomics|. Steve Levitt and Stephen Dubner return with a book that is even bolder, funnier, and more surprising than the first. Freakonomics made the world safe to discuss the economics of crack cocaine and the impact of baby names. SuperFreakonomics| retains that off-kilter sensibility (comparing, for instance, the relative dangers of driving while drunk versus walking while drunk) but also tackles a host of issues at the very centre of modern society: terrorism, global warming, altruism, and more.
