In this paper, we give new sufficient conditions for the existence of a solution of theg-maximum equality. As a consequence, we prove a new fixed point theorem. We also prove a new theorem of existence of Nash equilibrium.

In this paper, we study the main properties of the strong Berge equilibrium which is also a Pareto efficient (SBPE) and the strong Nash equilibrium (SNE). We prove that any SBPE is also a SNE, we prove also existence theorem of SBPE based on the KyFan inequality. Finally, we also provide a...

Based on the notion of equilibrium of a coalition P relatively to a coalition K, of Berge, Zhukovskii has introduced Berge equilibrium as an alternative solution to Nash equilibrium for non cooperative games in normal form. The essential advantage of this equilibrium is that it does not require...

In this paper, we give new sufficient conditions for the existence of a solution of theg-maximum equality. As an application, we prove a new fixed point theorem.

Emission trading systems have been recently proposed in diffrerent regions to reduce polluting emissions (e.g. in the European Union for carbon dioxide). One of the objectives of these systems is to encourage firms to adopt advanced abatement technologies. However permits create an incentive to...

This paper studies the concept of "mutual aid" developed by Kropotkin, which implies cooperation as a strategic choice. We study this concept in a Sequential Prisoners' Dilemma in a non-cooperative framework and in an indirect evolution framework (with complete and incomplete information). We...

Pour comprendre comment se font les atteintes à l'environnement, la notion de risque doit être étudiée sous tous ses aspects historique, cognitif, et bien sûr quant à son appréhension sociétale. Depuis l'alerte lancée par Ulrich Beck, très nombreuses sont les réflexions à ce sujet,...

Quels sont les risques financiers liés à la pollution pour une entreprise ? Ce rapport porte sur le marché de l'assurance du risque pollution en France. Par risque pollution, nous faisons référence aux risques financiers qu'entraîne, pour une entreprise, le fait d'être à l'origine d'une...

This paper discusses the growth model with environmental constraints recently presented in (Acemoglu et al., 2011) which focuses on the redirection of technical change by climate policies with research subsidies and a carbon tax. First, Acemoglu et al.'s model and chosen parameters yield...

This case study describes the social aspects of Total's CO2 integrated capture, transport and storage pilot project in Frontsouthwestern France, from the initial press conference February 8th, 2007 to the announce of its end in 2013. The economic and social context was favorable. The company...
