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...

This paper explores abatement investment and location responses to environmental policy, which takes the form of emission taxes or tradeable emission permits and subsidies against the costs of abatement investment, under uncertainty and irreversibility. Uncertainty is associated with output...

Total factor productivity growth (TFPG) has been traditionally associated with technological change. We show that when a factor of production, such as energy, generates an environmental externality in the form of CO₂ emissions which is not internalized because of lack of environmental policy,...

The present paper models jointly the evolution of compliance to regulation and the evolution of the CPR stock in the context of an evolutionary process emerging from combining replicator dynamics, which describe the adoption of harvesting rules, with resource stock dynamics. This evolutionary...

Emission taxes under oligopoly with both fixed number and endogenous market structure (perhaps the most relevant market structures for policy issues) are examined. In the latter case, and contrary to what is expected under imperfect competition, the optimal tax could exceed marginal external...
