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...

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....

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...
