question of core stability of the grand coalition, namely: is there a subset of bidders that prefers forming a small bidding … ring rather than participating in the grand cartel? We show that in the presence of direct externalities between bidders … the grand coalition is not necessarily core stable, as opposed to the zero externality case, where the stability of the …

The purpose of this article is to analyze a class of voting games in which externalities are present. We consider a … coalition formation of the outsiders. We show that whether or not the core is non-empty depends crucially on the expectations of … pessimistic expectations, then the core is non-empty if and only if the dimension of the set of alternatives is equal to one. On …

Their goal is to understand threat power. A second version of conflict theory has been … "real self-interested private conflicts". In other words, economic theory has considered social protesters either as looters …

allocation of resource and compensations among generations. Fairness is defined by core lower bounds and aspiration upper bounds …. The core lower bounds require that every coalition of generations obtains at least what it could achieve by itself. The …

Finding a solution concept is one of the central problems in cooperative game theory, and the notion of core is the …, one or several players with all their subordinates. In these situations, the core in its usual formulation may be … unbounded, making its use difficult in practice. We propose a new notion of core, called the restricted core, which imposes …

equilibrium are sketched ; they are the condition for a predictive power of the theory and its ability to allow for statics … many commodities and to a continuum of agents, some examples show how economic theory can accommodate the main ideas in …

important notion in cooperative game theory is the core of the game, as it contains the rational imputations for players. We … propose two definitions for the core of a multichoice game, the first one is called the precore and is a direct generalization … normalization at each level, causing the core to be a convex compact set. We study its properties, introducing balancedness and …

definition includes as a particular case the classical definition of pure exchange economy. We adapt the core concept to a … coalitional exchange economy, and we show the non-emptiness of the core. Finally, we discuss more general setting where individual …
