The Economics and Mathematics of Aggregation: Formal Models of Efficient Group Behavior

Abstract: The goal of this article is to provide a general characterization of group behavior in a market environment. A crucial feature of our approach is that we do not restrict the form of individual preferences or the nature of individual consumptions; we allow for public as well as private consumption, for intragroup production, and for any type of consumption externalities across group members. Our only assumption is that the group always reaches Pareto efficient decisions.
