We study and compare two frameworks: a model of influence, and command games. In the influence model, in which players are to make a certain acceptance/rejection decision, due to influence of other players, the decision of a player may be different from his inclination. We study a relation...

Finding a solution concept is one of the central problems in cooperative game theory, and the notion of core is the most popular solution concept since it is based on some rationality condition. In many real situations, not all possible coalitions can form, so that classical TU-games cannot be...

The paper concerns a model of influence in which agents make their decisions on a certain issue. It is assumed that each agent is inclined to make a particular decision, but due to a possible influence of the others, his final decision may be different from his initial inclination. Since in...

La recherche de l'harmonisation des diverses vocations des espaces littoraux ne doit pas seulement être synchronique; elle doit être aussi diachronique, c'est-à dire assurer la compatibilité entre les formes de développement actuelles et les nouvelles formes de développement qui...

The paper concerns a dynamic model of influence in which agents have to make a yes-no decision. Each agent has an initial opinion, which he may change during different phases of interaction, due to mutual influence among agents. The influence mechanism is assumed to be stochastic and to follow a...

We study cooperative games associated with a communication structure which takes into account a level of communication between players. Let us consider an undirected communication graph : each node represents a player and there is an edge between two nodes if the corresponding players can...

La scène énergétique mondiale, européenne et française est en train de vivre plusieurs bouleversements institutionnels et économiques qui auront des répercussions sur les choix techniques et le développement des filières : privatisation et ouverture des marchés de l'électricité et du...

Il est possible de distinguer différentes interventions fiscales par leur contenu empirique : taxe intérieure sur le produits pétroliers (TIPP), taxe sur la mise en décharge, etc. S'en tenir à une telle appréhension ne permet cependant pas de comprendre les points de débat les plus...
