In the past 50 years, economists have increasingly used insights from psychology to explore the limitations of the standard economic model of rational decision making - a field now known as "behavioral economics." This course is an introduction to the central concepts of behavioral economics, touching on related research in psychology and experimental economics. We will also discuss the public policy implications of this work, and current policy applications of behavioral research around the world. Topics covered include: self-control, procrastination, fairness, cooperation and reciprocity, reference dependence, and choice under uncertainty.
