An experimental investigation of Poisson Coordination games

Poisson games have been proposed to address equilibrium indeterminacy in Coordination games. They model the number of actual players as a Poisson randomvariable to capture population uncertainty in large games. Two natural questions are(a) whether uncertainty about the number of actual players does have an impact onsubjects' behavior, and if so (b) whether such behavior is consistent with the theoretical prediction of Poisson Coordination games. Investigating these questions is the focus of this paper. We find that uncertainty about the number of actual players may influence subjects' behavior. Crucially, such behavior is consistent with the theoretical prediction
