In many international river basins disputes over property rights to water lead to inefficient water allocation and a waste of resources. In this paper, we examine how contested water rights impede water trade. To show this, we use a model in which property rights to water are contested because...

Biodiversity loss has been recognized as one of the most important global environmental problems, but the choice of conservation policies is hampered by the lack of an operational concept of biodiversity. Weitzman (1992, 1998) develops a framework for the measurement of diversity and the...

In this paper we report results from a comparison of numerically calibrated game theoretic integrated assessment models that explore stability and performance of international coalitions for climate change mitigation. Specifically, by means of this ensemble of models we are able to identify...

We include initial holdings in the jungle economy of Piccione and Rubinstein (Economic Journal, 2007) in which the unique equilibrium satisfies lexicographic welfare maximization. When we relax assumptions on consumption sets and preferences slightly, equilibria other than lexicographic welfare...

We analyse river sharing games in which a set of agents located along a river shares the available water. Using coalition theory, we find that the potential benefits of water trade may not be sufficient to make all agents in the river cooperate and acknowledge property rights as a prerequisite...

We examine the role of support for coalition stability in common pool resource games such as fisheries games. Some players may not want to join a coalition that jointly manages a resource. Still, because they benefit from spillovers, they may want to support the coalition with a transfer payment...

In this paper I analyse the stability of cartels in games with heterogeneous players and externalities. I introduce a class of sharing rules for coalition pay-offs, called 'optimal sharing rules', that stabilize all cartels that are possibly stable under some arbitrary sharing rule. To...
