Global Climate Games: How Pricing and a Green Fund Foster Cooperation
The international game of cap and trade begins when countries choose their quantity targets, which are largely selected according to self interest. The analogous public-goods game, in which countries choose their abatement levels, has an uncooperative outcome. Compared to that, the Nash equilibrium of the cap-and-trade game shows that abatement can increase but that trade provides opportunities for uncooperative behavior. By contrast, a game in which all countries vote for a global quantity target or a global price target can lead to a highly cooperative choice of target. However, the assignment of responsibilities for a global quantity target stymies implementation of a global cap. The global-price-target game largely overcomes this barrier because a uniform global price provides a focal point for cooperation. However low-emission countries apparently prefer a much lower global-price than more prosperous countries unless a Green Fund is implemented. A game that couples such a fund to the global price target can largely overcome this barrier to cooperation. We describe such a game along with its equilibrium outcome, which promises to be inexpensive and cooperative.
