This paper considers the robustness of equilibria to a small amount of incomplete information, where players are allowed to have heterogenous priors. An equilibrium of a complete information game is robust to incomplete information under non-common priors if for every incomplete information game...

Cooperation in real-world dilemmas takes many forms. We introduce a class of two-player games that permits two distinct ways to cooperate in the repeated game. One way to cooperate is to play cutoff strategies, which rely solely on a player's private value to defection. The second cooperative...

This paper unifies the theories of Nash implementation and Bayesian implementation in a single framework. Environments considered are such that each agent's characteristics include, in addition to a specification of his private information, a commonly known type parameter, while both attributes...

For any given set-valued solution concept, it is possible to consider iterative elimination of actions outside the solution set. This paper applies such a procedure to define the concept of iterated monotone potential maximizer (iterated MP-maximizer). It is shown that under some monotonicity...

I analyze a bilateral bargaining model with one-sided uncertainty about time preferences. The uninformed player has the option of halting the bargaining process to obtain additional information, when it is his turn to offer. For a wide class of preference settings, the uninformed player does not...

Purification results are important in game theory and statistical decision theory. The purpose of this paper is to prove a general purification theorem that generalizes many authors' results. The key idea of our proof is to make use of the exact law of large numbers. As an application, we show...

This paper shows that in an incomplete information situation if the set of states of the society which occur with positive probability satisfies 'connection' condition, then closure condition will be satisfied by all social choice sets. It then follows from Jackson's (1991) two fundamental...

The article develops R. H. Coase’s insight that the level of transaction costs in the market determines the amount of externalities, thus providing arguments against government intervention. Contrary to Coase, however, we argue that the level of transaction costs cannot be considered as given,...

We describe a simple 2-stage mechanism that induces two bargainers to be truthful in reporting their reservation prices in a 1st stage. If these prices criss-cross, the referee reports that they overlap, and the bargainers proceed to make offers in a 2nd stage. The average of the 2nd-stage...

ABSTRACT This paper focuses on an ex post trading problem in inter-bank money markets. An “over the counter” inter-bank market is modeled in this paper. Relationship banking leads to private proprietary information that causes bargaining failure in such markets with positive probability....
