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...

Using a laboratory experiment, we behaviourally study the impact of a sudden increase in the common-pool size on within-group conflict, i.e., the paradox of the plenty. We also consider the potential role of governance in avoiding this paradox. In the first stage, a randomly-chosen leader of the...
