We present a cheap talk extension to any two-player, finite, complete information game, and ask what correlations over actions are implementable in Nash equilibria of the extended game. In the extension, players communicate repeatedly through a detail-free mediator that has been studied in...

We study a sealed-bid auction between two bidders with asymmetric independent private values. The two bidders own asymmetric shares in a partnership. The higher bidder buys the lower bidderʼs shares at a per-unit price that is a convex combination of the two bids. The weight of the lower bid is...

Two players can make use of a trusted third party who mediates and partially resolves their conflict. Usually, the mediator should be aware of the situation and give suggestions to the players accordingly. However, a corrupt mediator can have a big influence on the outcome of the game. We single...

We show that a set of outcomes outside the convex hull of Nash equilibria can be asymptotically stable with respect to convex monotonic evolutionary dynamics. Boundedly rational agents receive signals and condition the choice of strategies on the signals. A set of conditional strategies is...

This paper studies the problem of identifying and estimating the normal-form payoff parameters of a simultaneous, discrete game of complete information where the equilibrium concept employed is correlated equilibrium rather than Nash equilibrium. We show that once we extend the equilibrium...

This paper provides an explicit characterization of correlations that are implicitly captured by partition models for incomplete information games. The main result of this paper shows that every partition model for incomplete information can be decomposed into the conjunctions of a unique...

A game of incomplete information can be decomposed into a basic game and an information structure. The basic game defines the set of actions, the set of payoff states the payoff functions and the common prior over the payoff states. The information structure refers to the signals that the...

It is known that there are uncoupled learning heuristics leading to Nash equilibrium in all finite games. Why should players use such learning heuristics and where could they come from? We show that there is no uncoupled learning heuristic leading to Nash equilibrium in all finite games that a...

The paper studies the structure of the set of correlated equilibria for 2x2-bimatrix games. We find that the extreme points of the (convex) set of correlated equilibria can be determined very easily from the Nash equilibria of the game.

We extend Aumann's [3] theorem, deriving correlated equilibria as a consequence of common priors and common knowledge of rationality, by explicitly allowing for non-rational behavior. We replace the assumption of common knowledge of rationality with a substantially weaker one, joint p-belief of...
