Ideally, college classrooms provide students with a comfortable but challenging environment in which diverse ideas and viewpoints are openly exchanged; the reality they experience, though, is often quite different. In this episode, David Laibson joins us to discuss how Harvard University is attempting to identify and address barriers to this ideal. David is the Robert I. Goldman Professor of Economics and a Faculty Dean of Lowell House. He has published dozens of heavily cited articles on a wide range of topics, including behavioral economics, self-regulation, behavior change, household finance, and aging. David is a Research Associate in the Aging, Asset Pricing, and Economic Fluctuations Working Group at the National Bureau of Economic Research, member of the National Bureau of Economic Research, and serves on numerous advisory boards. He has received Harvard’s Phi Beta Kappa award and a Harvard College Professorship in recognition of his high quality teaching. David is also a co-author of popular textbooks on introductory economics and  a co-editor of the Handbook of Behavioral Economics.
