We introduce "group cohesion" to study the economic relevance of social relationships in team production. We operationalize measurement of group cohesion, adapting the "oneness scale" from psychology. A series of experiments, including a pre-registered replication, reveals strong positive...

The theory of repeated games offers a compelling rationale for cooperation in a variety of environments. Yet, its consequences for collective decision-making have been largely unexplored. In this paper, we propose a general model of repeated voting in committees and study equilibrium behavior...

We consider non-cooperative bargaining over a fixed surplus between two groups that may differ in size and the supermajority threshold they employ for within-group ratification. We find that total allocation to a group does not depend on group size and increases with the supermajority threshold....

Many positive externalities are created by individual risk-taking. We investigate whether risk-taking increases in the presence of positive externalities. In our experiments, we study choices between investments in technologies that differ according to their level of risk and the extent to which...

Using the multiple Emmy Award-winning television game show, Cash Cab, as a pseudo-laboratory, we find that the presence (or addition) of one powerful or influential female in (or to) a small (previously homogeneous male) group significantly reduces the group’s willingness to take qualitatively...

This paper considers a situation in which students with heterogeneous ability types are grouped into different competitions for performance ranking. A planner can group the students and design prize structure in each competition in order to maximize the weighted total performance subject to a...
