Ecological systems such as shallow lakes areusually non-linear and display discontinuitiesand hysteresis in their behaviour. Thesesystems often also provide conflicting servicesas a resource and a waste sink. This impliesthat the economic analysis of these systemsrequires to solve a non-standard...

In nonpoint source pollution problems, the regulator does not observe each polluter’s individual emission, which prevents him from using the conventional policy instruments. Therefore, new instruments have been designed to regulate this type of pollution. In an experiment, we compare the...

The paper examines the relation between countries' state of the environment (defined as acceptable, marginal or unacceptable, according to values of ambient accumulation of pollutants) and stage of economic development (defined as low, middle and high income), using the concentration of sulphur...

The simultaneous management, in an international context, of free-access renewable resources and transboundary pollution, is examined in a dynamic game framework. First-best outcomes under international cooperation are determined and compared to noncooperative outcomes when countries follow...

Although there is widespread agreement about the dangers of global warming and the resulting need to cut down emissions, there does not seem to be general agreement about the exact form the policy should take or the timing of its adoption. Failure to adopt and implement policies against global...
