This paper studies Bayesian games with general action spaces, correlated types and interdependent payoffs. We introduce the condition of ``decomposable coarser payoff-relevant information'', and show that this condition is both sufficient and necessary for the existence of pure-strategy equilibria and purification from behavioral strategies. As a consequence of our purification method, a new existence result on pure-strategy equilibria is also obtained for discontinuous Bayesian games…

Pure-strategy equilibria in Bayesian games

On the Existence of Monotone Pure Strategy Equilibria in Bayesian Games

We generalize Athey's (2001) and McAdams' (2003) results on the existence of monotone pure strategy equilibria in Bayesian games. We allow action spaces to be compact locally-complete metrizable

Distributional Strategies for Games with Incomplete Information

Using the notion of “distributional” strategies, this work proves four main theorems: (i) a mixed-strategy Nash equilibrium existence theorem, (ii) a pure-str strategy equilibrium existenceorem, (iii) apure-strategic (epsilon-equilibrium existence theorem), and (iv) a theorem describing how the set of equilibria of a game varies with the parameters of the game.

Private Information and Pure-Strategy Equilibria

In this paper it is proved that in games with a finite number of players and a finite number of moves, if each player observes a private information random variable which has an atomless distribution

Single Crossing Properties and the Existence of Pure Strategy Equilibria in Games of Incomplete Information

A class of games of incomplete information where each agent has private information about her own type, and the types are drawn from an atomless joint probability distribution is analyzed, establishing existence of pure strategy Nash equilibria (PSNE) under a condition called the single crossing condition.

Nash and Bayes–Nash equilibria in strategic-form games with intransitivities

We study games with intransitive preferences that admit skew-symmetric representations. We introduce the notion of surrogate better-reply security for discontinuous skew-symmetric games and elucidate
