Integrating and refining social interdependence theory and structural adaptation theory, we examined the effects of intergroup competition on the creativity of 70 four-person groups engaged in two idea generation tasks. We manipulated both group membership change (change, no change) and intergroup competition level (low, intermediate, high). Competition had the expected U-shaped relation with c...

In social media, users might join groups based on shared taste or c...

In this paper, I illustrate the importance of both dynamics and network constraints in the group formation process. I introduce a class of games called sequential group formation games, in which players make their group membership decisions sequentially over time, and show that the dynamics act as an equilibrium refinement. However, the resulting equilibrium is highly suboptimal–groups tend to ...
