"My research focuses on cooperation and exchange. I study a wide range of situations in which group members gain by cooperating but where a temptation to behave selfishly exists, examining the factors that encourage or discourage the emergence of cooperation, community, and trade. I also study the social aspects of formal and informal markets. My research methods include experiments, fieldwork, and computer simulations. My recent work has concentrated on studies of online communities and markets."
