Common pool resource dilemmas under uncertainty: Qualitative tests of equilibrium solutions

The Common Pool Resource (CPR) dilemma game is a single-stage noncooperative game in which n players share a CPR whose size, X, is a random variable with a commonly known probability distribution. We present the equilibrium solutions for CPR games in which X has a uniform distribution, players have power utility functions with a common parameter, c, and requests are made simultaneously or sequentially. Two experiments using groups of n = 5 players provide support for the major qualitative predictions of the model.
