20 years ago, a book called Freakonomics became an instant bestseller and worldwide sensation. Tim Harford got his hands on the first copy that Steve Levitt ever signed... and promptly sold it on eBay. In this Cautionary Conversation, the pair are reunited to discuss the Freakonomics phenomenon, why Levitt left the hostile world of academia, and how simple changes could revolutionise everything from education to organ donation.
