There are only few "positive" results concerning multi-person games with the fictitious play property, that is, games in which every fictitious play process approaches the set of equilibria. In this paper we characterize classes of multi-person games with the fictitious play property. We...

This paper develops an approach for valuing Internet Service Providers (ISPs). The viewpoint is taken that once access to the Internet is obtained it can then be characterized by non-rivalrous consumption and non-exhaustibility. However, the quality of access is affected by the capacity of the...

The literature on minimum effort game has been concerned with a symmetric game with linear payoff functions. The main aim of the present paper is to study the coordination problem arising in a not necessarily symmetric minimum effort game with two players. The sources of asymmetry can be...

This paper concerns a class of nonstationary discrete-time stochastic noncooperative games. Our goals are threefold. First, we give conditions to find Nash equilibria by means of the Euler equation approach. Second, we identify subclasses of dynamic potential games. Finally, within one of this...

Nous analysons les phénomènes de contagion apparaissant dans des situtions d?interaction locale ou globale. Nous utilisons les réseaux de neurones pour étudier ces phénomènes. Contrairement à beaucoup de modèles, un état de système décrit la structure spatiale des choix et non pas...

In a strategic game, a curb set (Basu and Weibull, Econ Lett 36:141–146, 1991) is a product set of pure strategies containing all best responses to every possible belief restricted to this set. Prep sets (Voorneveld, Games Econ Behav 48:403–414, 2004) relax this condition by only requiring...

This paper introduces games with a saddle function. A saddle function is a real valued function on the set of action profiles such that, for one player, minimizing the function implies choosing her best-response, and, for the other players, maximizing it implies choosing their best-responses. We...

We introduce several methods of decomposition for two player normal form games. Viewing the set of all games as a vector space, we exhibit explicit orthonormal bases for the subspaces of potential games, zero-sum games, and their orthogonal com- plements which we call anti-potential games and...

This paper proposes a new class of potential games, the nested potential games, which generalize the potential games defined in Monderer and Shapley (1996), as well as the pseudo-potential games defined in Dubey et al. (2006). We show that each maximizer of a nested potential is a Nash equilibrium.
