Title: "Diversity in Committees"  (joint work with Niall Hughes and Zia UH Khan)

Abstract: We investigate the potential of diversity to influence committee decision-making. We present a model in which committee members receive private information on a state of the world, deliberate and vote. Committee members belong to one of two groups which may differ along two dimensions: (a) their preferences and (b) their information structures. Diverse committees outperform other committees if information structures are correlated within groups and preferences are aligned. With heterogeneity in preferences, homogeneous committees do better than some, but not all diverse committees. We test the model's key predictions in a laboratory experiment. The model's predictions are largely borne out. Diverse committees outperform homogeneous committees when information structures are correlated and preferences are aligned, but they do not do worse even when preferences are misaligned. The reason is that participants reveal more information than theory predicts and update imperfectly.
