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...

Paragraph 31(iii) of the Doha Ministerial Declaration mandates to the liberalization of environmental goods and services. This mandate offers a good opportunity to put climate-friendly goods and services on a fast track to liberalization. Agreement on this paragraph should represent one...

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...

A two-tier climate club exploits the comparative advantage of large countries to mete out punishments through trade, while taking their capacity to resist punishment as a constraint. Countries outside the coalition price carbon at a fixed fraction of the average carbon price adopted within the...

International carbon offsets have been promoted since the Kyoto Protocol and an increasing number of countries have implemented or proposed cap-and-trade schemes with international trading, even though with quantitative or qualitative restrictions. Those limits reflect the trade-off between...

International climate negotiations take place in a setting where uncertainties regarding the impacts of climate change are very large. In this paper, we examine the influence of increasing the probability and impact of large climate change damages, also known as the 'fat tail', on the formation...

After twenty years of global negotiations, the world is still far from a comprehensive climate agreement. The "top-down" approach embodied by the Kyoto Protocol has all but stalled, chiefly due to disagreements over levels of ambition and objections to financial transfers. To avoid those...

If the threshold that triggers climate catastrophe is known with certainty, and the benefits of avoiding catastrophe are high relative to the costs, treaties can easily coordinate countries' behavior so as to avoid the threshold. Where the net benefits of avoiding catastrophe are lower, treaties...
