Consider a situation in which countries anticipate an international environmental agreement (IEA) to be in effect sometime in the future. What is the impact of the future IEA on current emissions after its announcement? We show that the answer to this question is ambiguous. We examine four types...

In this paper, we discuss the endogenous formation of climate coalitions in an issue-linkage regime. In particular, we propose to build a link to the issue of preferential free trade. Trade privileges exclusively granted to members of the climate coalition work as an incentive mechanism for...

We study the endogenous formation of climate coalitions linked to a preferential free trade arrangement. In a multi-stage strategic trade and participation game, coalition and fringe countries dispose of a discriminatory tariff on dirty imports as well as emission permits imposed on domestic...

This paper examines the effects of political pressure groups (lobbies) on the emissions abatement decisions of countries and on the stability of international environmental agreements. We consider two types of lobbies, industry and environmentalists. We determine the influence of lobby-groups on...

I explore possible impacts of reciprocal preferences on participation in international environmental agreements. Reciprocal countries condition their willingness to abate on others' abatement. No participation is always stable. A full or majority coalition can be stable, provided that...

International climate negotiations have been troubled by mutual mistrust. At the same time, a hope seems to prevail that once enough countries moved forward, others would follow suit. If the abatement game faced by climate negotiators is a Prisoners' Dilemma, and countries are narrowly...

The Conference of the Parties (COP) has proven a valuable outlet to advance the climate agenda. The combination of high media coverage, extremely high expectations set by influential environmentalists, and unanimity rules has, however, started to limit its effectiveness. Technical issues can...

Our purpose is to analyse the effectiveness and efficiency of a Partial Climate Agreement with open entry under a non-cooperative Nash-Equilibrium framework. We evaluate a partial agreement policy in which non-signatory countries can decide to join or to leave a coalition of the willing at any...

Solar geoengineering has received increasing attention as an option to temporarily stabilize global temperatures. A key concern surrounding these technologies is that heterogeneous preferences over the optimal amount of cooling combined with low deployment costs may allow the country with the...
