Under appropriate assumptions (private values and uniform punishments), the Nash equilibria of a Bayesian repeated game without discounting are payoff-equivalent to tractable, completely revealing, equilibria and can be achieved as interim cooperative solutions of the initial Bayesian game. This...

The ex ante incentive compatible core of an exchange economy with private information is the (standard) core of a socially designed characteristic function, which expresses the fact that coalitions allocate goods by means of random incentive compatible mechanisms. We first survey some results in...

We propose a semi-cooperative game theoretic approach to check whether a given coalition is stable in a Bayesian game with independent private values. The ex ante expected utilities of coalitions, at an incentive compatible (noncooperative) coalitional equilibrium, describe a (cooperative)...

We interpret the TV-show Come Dine with Me as a simultaneous non-cooperative game with evaluation levels as strategic variables, and show that it belongs to a class of strategic games which we label mutual evaluations games (MEG). Any MEG possesses a ‘zero equilibrium' — i. e. a Nash...

In the basic model of the literature on international environmental agreements (IEAs) (Barrett 1994; Rubio and Ulph 2006) the number of signatories of self-enforcing IEAs does not exceed three, if non-positive emissions are ruled out. We extend that model by introducing a composite consumer good and...

We analyze the revenue-enhancing potential of favoring specific contestants in complete information all-pay auctions and lottery contests with several heterogeneous contestants. Two instruments of favoritism are considered: head starts that are added to the bids of specific contestants and...

This paper utilizes a simple model of redistributive politics with voter abstention to analyze the impact of nonpartisan ‘get-out-the-vote' efforts on policy outcomes. Although such efforts are often promoted on the grounds that they provide the social benefit of increasing participation in...

This paper provides existence and characterization of the optimal contest success function under the condition that the objective of the contest designer is total effort maximization among n heterogeneous players. Heterogeneity of players makes active participation of a player in equilibrium...
