This paper examines sets of Nash equilibrium in sender-receiver games that are stable against replacement by alternative Nash equilibria. Such stable sets exist. In partial common interest games they contain only informative equilibria.

The paper deals with the literature on social evolution.

This paper explores the quantitative relation between non-random, assortative matching and the maintenance of cooperative behavior under evolutionary dynamics.

A hostage with respect to an action of a player is defined here to be an amount ofpayoff that will be placed in the opponent's possession if the player takes the action. Whereas the only Nash equilibrium for a prisoner's dilemma game is mutual defection, it is shown that there are at most two...

Voting Power Indices enable the analysis of the distribution of power in a legislature or voting body which uses weighted voting. Although the approach, based on co-operative game theory, has been known for a long time it has not been very widely applied, in part because of the difficulty of...

This paper formalizes the relation between comparative statics and the out-of-equilibrium explanation for how a system evolves after a change in parameters.

This paper presents a general method for computing value conrrespondences under perfect monitoring and discounting.

This paper generalizes the results of Suijs, De Waegenaere and Borm (1998) to arbitrary risks. It provides Pareto optimal allocations and shows that the zero utility premium calculation principle yields a core-allocation.

This paper analyzes linear production situations with price uncertainty, and shows that the corresponding stochastic linear production games are totally balanced. It also shows that investment funds, where investors pool their individual capital for joint investments in financial assets, fit...

The class of neighbour games is the intersection of the class of assignment games (cf. Shapley and Shubik (1972)) and the class of component additive games (cf. Curiel et al. (1994)). For assignment games and component additive games there exist polynomially bounded algorithms or order p4 for...
