In this paper we study the formation and the stability of International Environmental Agreements (IEAs) in a pollution abatement model with a quadratic cost function. Countries play a two-stage game: in the first stage each country decides to join or not the coalition while, in the -second...

The paper investigates the stability of the International Environmental Agreement in a model of emission reduction. We consider a two stage game, in which in the first stage each country decides whether or not to join the agreement while, in the second stage, the quantity of emissions reduction...

In this paper we propose the state of art in the theory of coalitional games in effectiveness form without bargaining between coalitions. We study some solution concepts: The largest consistent set (Chwe, 1994); the largest cautious consistent set (Mauleon et al., 2004); the credible consistent...

We model an International Environmental Agreement as a two stages game: during the first stage each country decides whether or not to join the agreement while, in the second stage, the quantity of emissions reduction is choosen. Players determine their abatement levels in a dynamic setting,...

In this paper we propose a model describing the commercial exploitation of a common property renewable resource by a population of agents. Players can cooperate or compete; cooperators maximize the utility of their group while defectors maximize their own profit. The model provides for one...
