I present in this paper an integrated framework for structuring and evaluating dynamic and sequential climate change decision making in the international arena taking into account influence processes occuring during negotiation rounds. The analysis integrates imitation, persuasion and dissuasion...

This note incorporates ecological interactions into the Noah's Arch problem [M.L. Weitzman, The Noah's Arch problem, Econometrica 66(6) (1998) 1279-1298]. In doing so, we arrive at a general model for ranking in situ conservation projects accounting for species interrelations and provide an...

In many Sub-Saharan African countries, farmers typically have a choice between selling their pro ducts to traders who travel between villages and markets and transporting their products to the nearest market themselves. Because of communities' remoteness and poor communications with...

We describe in this paper an evolutionary game theoretic model aiming at representing the climate change negotiation. The model is used to examine the outcome of climate change negotiations in a framework which seeks to closely represent negotiation patterns. Evolutionary setting allows us to...

Nous étudions une négociation à offres alternées visant à la ratification d’un accord international sur le changement climatique. Trois coalitions aux intérêts divergents sont considérées : la coalition des pays développés pro-régime menée par l’Union européenne, la coalition...

Le présent papier s'articule autour des problèmes environnementaux globaux, et se propose de lier les négociations internationales au comportement de précaution. Cela nous conduit à montrer que le comportement de précaution peut aussi bien survenir à la suite d'un échec des négociations...

We examine in this paper the formation and the stability of international environmental agreements when cooperation means to commit to a minimum abatement level. Each country decides whether to ratify the agreement and this latter enters into force only if it is ratified by a number of countries...

Global issues such as climate change, depletion of the ozone layer and bio-diversity loss call for a coordination of national environmental policies. In this paper, we focus on the conditions for mediation to promote cooperation. We consider two coalitions of countries that participate in an...

We consider a bargaining game aiming at the full ratification of a climate treaty. Three distinct coalitions are considered: a pro-regime coalition, the so-called Kyoto group, an anti-regime coalition made of the countries rejecting the Kyoto protocol and the G77 coalition made of developing...
