We study adaptation to climate change in a federalist setting. To protect themselves against an increase in flood risk, regional governments choose among adaptation measures that vary with respect to their costs, the level of protection they offer, and the presence and nature of spillovers to...

We take a decentralized approach to regulating environmental pollution in settings where each agent's pollution possibly affects all others. There is no central agency to enforce pollution abatement or coordinate monetary transfers. Moreover, agents possess private information, which precludes...

We consider the well-analyzed abatement game (Barrett 1994) and prove that correlation among the players (nations) can strictly improve upon the Nash equilibrium payoffs. As these games are potential games, correlated equilibrium - CE - (Aumann 1974, 1987) cannot improve upon Nash; however we...

We focus on an international technology agreement (ITA) in which the signatories collectively decide whether to conduct research and development regarding environmental technology. The aim of this study is to investigate how the co-benefits of adopting environmental technology affect the...

This paper examines the climate change treaties with cooperative R&D that brings about substantial reduction in greenhouse gas emission. By developing a joiner's gain function, we present a new approach under which countries that have invested in R&D can recover their R&D costs by breakthrough...

This paper explores the failure of countries to coordinate climate policies as an equilibrium outcome of a game where countries optimize in the face of both unprecedented economic and environmental uncertainty. Because issues associated with climate change are historically unprecedented and thus...

Acid rain causes greater environmental damage than would occur if countries act cooperatively. Based on new estimates of sulphur abatement cost functions, the potential gains from cooperation are calculated for Europe. Various cooperative abatement rates are compared with the rates implied by...
