  Building upon Aumann’s formal treatment, Brian Skyrms (1996) and Peter Vanderschraaf (1998b, 2001) argue that we should treat convention as a kind of correlated equilibrium. For example, consider the convention that drivers at traffic intersections correlate their actions with the color of the traffic signal. As the restaurant and traffic examples illustrate, correlated equilibria often provide far more satisfactory solutions to coordination problems than one could otherwise achieve.
