This model deals with the greenhouse effect, that is to say with a problem of international pollution. Through a description of the bargaining process, it aims to determine the different forms that may be taken by cooperation agreements between the countries involved. We demonstrate, in...

Endogenous growth is generally built on a positive externality hypothesis which is the opposite of a negative externality caused by pollution. We study a linear technology with simple assumption: an aggregate capital stock which represents a learning by doing effect and a pollution flow...
