Harmful algal bIoom species are the cause of important damages to marine living resources and human beings. These marine species are primarily introduced in North-European waters through ballast water, i.e. water trans-ported across the oceans so as to keep a vessel in balance. Port authorities...

In this paper the efficient allocation of natural recreational areas is analysed. Natural recreational areas have the features of public goods. We present the efficient allocation of this non-excludable public good in a rational general equilibrium model with heterogeneous agents. This allows us...

Many economic problems can be formulated as dynamic games in which strategically interacting agents choose actions that determine the current and future levels of a single capital stock. We study necessary conditions that allow us to characterize Markov perfect Nash equilibria (MPNE) for these...

This discussion paper led to the article with the same title in 'Social Choice and Welfare' (2014), 43, 173-194.<P> We consider the problem of sharing water among agents located along a river. Each agent has quasi-linear preferences over river water and money, where the benefit of consuming an...</p>

Many water allocation agreements in transboundary river basins are inherently unstable. Due to stochastic river flow, agreements may be broken in case of drought. The objective of this paper is to analyze whether water allocation agreements can be self-enforcing, or sustainable. We do so using...

In the search for effective pesticide risk management tools, the design of pesticide risk indicators is nowadays receiving increasing attention as a complement to more established regulatory strategies. In the present paper, we apply some recently developed pesticide risk indices and test their...

One of the policy options to increase the efficiency in the provision of scarce water resources is a reduction in transaction costs in water chains by developing integrated forms of water management. Integrated water management in case of river basin areas may comprise inter alia: (1) increasing...
