The impacts of climate change on human systems depend not only on the level of emissions but also on how inherently vulnerable these systems are to the changing climate. The large uncertainties over future development and structure of societies and economies mean that the assessment of climate...

While calls are being made to deal with the linkages between climate change and sustainable development to arrive at an integrated policy, concrete steps in this direction have been very limited so far. One of the possible instruments through which both issues may be approached simultaneously is...

Do countries interact when they decide whether or not to ratify the Kyoto Protocol? If so, what is the nature of these interactions? To answer these questions, we provide a theoretical analysis based on the notions of strategic substitutability and strategic complementarity. Firstly, we analyze...

Is there a strategically beneficial time for political leaders to make international environmental commitments? Based on the political cycles theory we argue that leaders have incentives to delay costly ratification of international environmental agreements to the post-electoral period. However,...

In coalitional games with side payments, the core predicts which coalitions form and how benefits are shared. The predictions however run into difficulties if the core is empty or if some coalitions benefit from not blocking truthfully. These difficulties are analyzed in games in which an a...

A spatial model of coalition formation is used together with data from Dutch elections and theoretical instances to study different procedures of coalition formation. The model shows that procedure plays an important role in reaching a coalition agreement and that political parties do not...

We consider in this paper solutions for TU-games where it is not assumed that the grand coalition is necessarily the final state of cooperation. Partitions of the grand coalition, or balanced collections together with a system of balancing weights interpreted as a time allocation vector are...

We present an application of relational algebra to coalition formation. This leads to specifications, which can be executed with the help of the RelView tool after a simple translation into the tool's programming language. As an example we consider a simplification of the situation in Poland...
