INTERNATIONAL CLIMATE AGREEMENTS AND THE SCREAM OF GRETA
ABSTRACT
The world is in immediate peril, as countries are not doing enough to keep Earth's temperature from rising to near-catastrophic levels, and various attempts at international cooperation have failed. Why is this problem so intractable? Can we expect an 11th-hour solution to the problem? Will some of the countries, or even all, succumb on the equilibrium path? We address these questions through a formal model that emphasizes the role of two major issues: the intra-temporal externalities that a country's policies exert on other countries, and the inter-temporal externalities that the current generation's policies exert on future generations. We examine the interaction between these two issues and the extent to which international agreements can mitigate the problem.
