We run a laboratory experiment with a two-person game with unique pure Nash equilibrium which is also the solution of the iterative elimination of strictly dominated strategies. The subjects are asked to commit to a device that randomly picks one of three symmetric outcomes in this game...

We consider the well-analyzed abatement game (Barrett 1994) and prove that correlation among the players (nations) can strictly improve upon the Nash equilibrium payoffs. As these games are potential games, correlated equilibrium - CE - (Aumann 1974, 1987) cannot improve upon Nash; however we...

This paper studies the problem of endogenous coalition formation in contests: how players organize themselves in groups when faced with the common objective of securing a prize by exerting costly effort. The model presented adopts an axiomatic approach by assuming certain properties for the...
