This three-quarter sequence is designed for advanced Social Science Ph.D. students with the aim of introducing students to the methodology of modern experimental economics and to provide an in-depth overview of the contributions of experimental methods to a wide variety of fields. The specific topics covered, which will vary from year to year, include but are not limited to individual decision making, preference and belief elicitation, game theory, social learning, bargaining, labor economics, public finance, auctions, voting and elections, competitive markets, networks, matching, mechanism design, coordination/communication, and information aggregation. The focus will be on theory-based experiments and how the dialog between theoretical analysis and laboratory data feeds each other, thereby leading to new avenues of theoretical and experimental research.
