We present typical scenarios and general insights from a novel dynamic model of farsighted climate coalition formation involving market linkage and cap coordination, using a simple analytical model of the underlying cost-benefit structure. In our model, the six major emitters of CO2 can link...

As the Copenhagen Accord indicates, most of the international community agrees that global mean temperature should not be allowed to rise more than two degrees Celsius above preindustrial levels to avoid unacceptable damages from climate change. The scientific evidence distilled in the Fourth...

A formal framework for the treatment of hierarchical coalition formation and hierarchical agreements under both the bargaining and blocking approaches to coalition formation is introduced, and some first positive results on the possibility of full agreement and the efficiency of hierarchical...

Using Putnam’s two‐level game approach, we discuss the influence of domestic players that can veto the ratification of international environmental agreements on the breadth and depth of such treaties. We first show that in a symmetric Barrett‐type payoff model, veto-players can restrict...

Are there collective decision methods which (i) give everyone, including minorities, an equal share of effective power even if voters act strategically, (ii) promote consensus and equality, rather than polarization and inequality, and (iii) do not favour the status quo or rely too much on...

The expected number of pairwise comparisons needed to learn a partial order on n elements is shown to be at least /4 − (), and an algorithm is given that needs only /4 + () comparisons on average. In addition, the optimal strategy for learning a poset with four elements is presented

It is shown that each continuous transformation from Euclidean -space ( > 1) into Euclidean -space that preserves the equality of distances (that is, fulfils the implication is a similarity map. The case of equal dimensions already follows from the Beckman-Quarles Theorem

Actual individual preferences are neither complete (=total) nor antisymmetric in general, so that at least every must be an admissible input to a satisfactory choice rule. It is argued that the traditional notion of “indifference” in individual preferences is misleading and should be...
