In this paper we investigate effects of overlap in species between ecosystems along a linear gradient on the location of marine protected areas (MPAs) under full cooperation, strategic behavior and conservation autarky. Compared to the full cooperation outcome, both strategic behavior and...

This paper surveys the recent literature on the political economy of the formation of international environmental agreements. The survey covers theoretical modelling approaches and empirical studies including experimental work. Central to our survey is the question how the political process...

Sustainable agricultural growth in developing countries is jeopardized by soil degradation consequent upon intensive cultivation and use of increasing doses of chemical inputs. To pave the way to sustainable agricultural growth we develop a model that incorporates organic fertilizer into the...

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 su cient to make all agents in the river cooperate and acknowledge property rights as a prerequisite for...

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 introduce the notion of a stone age equilibrium to study societies in which property rights are absent, bilateral exchange is either coercive or voluntary, and relative strength governs power relations in coercive exchange. We stress the importance of free disposal of goods which allows for...
