Environmental problems with unknown emission abatement cost and damage are analyzed. The game under consideration is static, and its expected payoff structure displays a prisoners’ dilemma. Even in this most unfavorable setting cooperation might arise if the involved countries are sufficiently...

To limit global environmental risks, countries must cooperate. However, the prisoners' dilemma-type of the problem suggests that international environmental agreements are difficult to obtain and to maintain. In this paper, the role of countries' risk preferences for the prisoners'...

This paper models global environmental policy in a stochastic setting: reducing pollution not only reduces expected environmental damage but also its spread. The national incentives to cooperate are analysed under adverse conditions: expected payoffs are taken to have the structure of a (static)...
