We show that a rational expectations equilibrium need not be incentive compatible, need not be implementable as a perfect Bayesian equilibrium and may not be fully Pareto optimal, unless the utility functions are state independent. A comparison of rational expectations equilibria with core...

We show, by employing a density result for probability measures, that in games with a finite number of players and \infty-dimensional pure strategy spaces Nash equilibria can be approximated by finite mixed strategies. Given 0, each player receives an expected utility payoff /2 close to his Nash...

In the context of extensive form games, we are considering the relation between mixed and behavioural strategies. We look again at the famous Kuhn theorem and also discuss a result for games in which no path intersects any information set in more than one node. We apply the principle...
