Contributor(s): Professor Cass R. Sunstein | Friedrich Hayek argued for freedom of choice based on outsiders knowing much less than choosers so that interferences with personal freedom will make choosers worse off. This lecture will explore the challenge to that argument that comes from behavioural economics and discusses an ongoing program of research which has created a form of Hayekian behavioural economics.
