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...

We axiomatize the inner core in a similar way as the one proposed by Aumann (1985)in order to characterize the NTU value.

Voting Power Indices enable the analysis of the distribution of power in a legislature or voting body in which different members have different numbers of votes. Although this approach to the measurement of power, based on co-operative game theory, has been known for a long time its empirical...

The paper considers an extension of the original Shapley and Shubik (1972) two-sided matching problem to the case of multisided matching with transfereable utility. We investigate existence and properties of stable matchings using the approach of cooperative game theory.

The aim of this paper is to present a new value of a cooperative game for the case of limited communication between players. The communication system we consider may be represented by a simple graph, that is, only pairwise meetings can occur and some of them are not permitted. An associated game...

This paper describes the historical evolution of the analysis of some aspects of the strategic use of information. The use of mixed strategies aims to create uncertainty on the move to be played or on the private information of the players. In a repeated game framework, strategic behavior when...

This paper examines the implementation of two public ownership solutions in convex production economies with differentiable production functions. The two public ownership solutions we focus on are the proportional and equal benefit solutions. Two "natural" mechanisms which doubly implement the...

We study endogenous coalition formation in contexts where individual (and group) payoffs depend on the entire coalition structure that might form. We capture potential interaction across coalitions by means of a partition function.
