We consider a class of symmetric two-person quadratic games where coarse correlated equilibria – CCE – (Moulin and Vial [16]) can strictly improve upon the Nash equilibrium payoffs, while correlated equilibrium – CE – (Aumann [3,4]) cannot, because these games are potential games with...

We explore whether competitive outcomes arise in an experimental implementation of a market game, introduced by Shubik (1973) [21]. Market games obtain Pareto inferior (strict) Nash equilibria, in which some or possibly all markets are closed. We find that subjects do not coordinate on autarkic...
