GAME-THEORY AND THE POLITICS OF THE GLOBAL COMMONS

I assume that politicians maximize domestic political support subject to a political feasibility constraint set by the relationship between environmental quality and some politically desirable economic performa nce indicator. Because pollution flows across national frontiers, the political feasibility frontier depends on other nations' environmental policies. Depending on the nature of domestic political pressures and the environmental spillovers between the countries, various game stru ctures are possible. Knowledge of the structure of the game is helpful when addressing policy issues and the question of how to design inter national institutions in order to overcome international environmental collective action problems.
