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...

There is an abundant and growing literature on the ramifications of artificial intelligence (AI) for society. This paper contributes some formal observations about the influence AI might have on how people who participate in small groups interact. Within such groups (say a team, business unit,...

We study the effects of group identity on cooperation in experimental two-person strategic games. Our results show that in games of strategic complements, group identity only matters initially when a participant interacts with another participant of the same group by delivering more cooperative...

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...
