We propose a five-player common-pool resource (CPR) game with endogenous coalition formation. We show that the level of extraction from the CPR depends on the size of each coalition that is formed and on the final coalition structure. These predictions are tested in a laboratory experiment. We...

We study experimentally a two-stage common pool resource game. In the first stage, selected members of the group determine the level of protection for the resource. The protected fraction of the resource is equally shared among group members. In the second stage, the unprotected fraction of the...
