The Impact of Unilateral Commitment on Transboundary Pollution

To reach a common target of environmental quality, countries can choose to commit to a stream of pollution abatement right from the beginning of the game or decide upon abatement at each moment of time. Though most of the previous literature studies homogeneous strategies where no country or all countries commit to a (same) predefined policy, reality goes along a different way: some countries make more efforts than others to reduce pollutant emission. The main novelty of this paper resides in the introduction of this kind of heterogeneous strategic behavior currently observed among large pollution nations. We find that the pollution level can be lower under heterogeneous than under homogeneous strategies. A stringent environmental quality target will induce the committed player to produce an abatement effort that more than compensates the free-riding attitude of the non-committed player.

The Strategic Impact of Adaptation in a Transboundary Pollution Dynamic Game

This work studies the strategic impact of a region’s investment in adaptation measures on the equilibrium outcomes of a transboundary pollution dynamic game played in finite horizon. We incorporate adaptation as a region-specific capital stock that decreases local damages and study the feedback (subgame perfect) equilibrium of the non-cooperative game between two regions. In order to discern the impact of adaptation, we compare the equilibrium solutions of three scenarios, which differ in the regions’ ability to invest in adaptation measures. The results show that investing in adaptation gives regions an incentive to increase their emissions, which causes an inverse strategic response in the other region. The anticipation of a rise in pollution makes the other region respond by cutting its emissions and investing more in adaptation. The equilibrium trajectories of the stocks of pollution and adaptation capital follow the highest path over time when both regions adapt. When there is an asymmetry between regions in their adaptation capabilities, the region that does not (or cannot) adapt becomes worse off due to lower emissions and higher damages, while the adapting region finishes the game better off than the no-adaptation case.     

Collaborative Science, Policy Development and Program Implementation in the Transboundary Georgia Basin/Puget Sound Ecosystem

The transboundary Georgia Basin Puget Sound ecosystem is situated in the southwest corner of British Columbia and northwest comer of Washington State. While bountiful and beautiful, this international region is facing significant threats to its marine and freshwater resources, air quality, habitats and species. These environmental challenges are compounded by rapid population growth and attendant uiban sprawl. As ecosystem stresses amplified and partnerships formed around possible solutions, it became increasingly clear that the shared sustainability challenges in the Georgia Basin and Puget Sound required shared solutions. Federal, state and provincial institutional arrangements were made between jurisdictions, which formalized small scale interest in transboundary management of this ecosystem. Formal agreements, however, can only do so much to further management of an ecosystem that spans international boarders. A transboundary regional research meeting, the 2003 GB/PS Research Conference, opened the doors for large-scale informal cross-boarder cooperation and management. In addition to cooperation, continued efforts to stem toxic pollution, contain urban growth, and protect and restore ecosystems, require a commitment from scientists, educators and policy makers to better integrate research and science with decision-making.Former Director of Planning and of Special Projects in the British Columbia Ministry of Municipal Affairs.     

Capacity utilization and investment in environmental quality

This paper characterizes the optimal use of productive capacity and optimal investment in environmental quality when the latter has a positive impact on the production process. For the case of a single country, we find conditions under which capital should or should not be fully utilized, and investment in environmental quality should be positive or zero. We then extend the model to the case of two countries playing a non-cooperative dynamic game. The Nash equilibrium turns out to be a dominant-strategy equilibrium. Since this equilibrium is not Pareto efficient, we show how one country may bribe the other country to achieve a better outcome, for example, by refraining from full utilization of capacity. Under certain conditions, the optimal solution requires that a constant fraction of one country's income be used to bribe the other country to scale down its production.

An Efficient Pollution Control Instrument: The Case of Urban Wastewater Pollution

Urban wastewater and agriculture activities are the main sources of urban water pollution and of eutrophying nutrients in many water ecosystems. Several EU directives have been adopted and affect the control of urban water pollution. The EU legislation requires the achievement of good ecological and chemical status in all water. This paper focuses on the use of economic instruments as a priority in the context of implementation. Our analysis only considers public wastewater utilities facing demand and capacity shocks. The proposed mechanism constitutes efficient means of moving towards sustainability by promoting full-cost pricing and considering external costs from wastewater services. Environmental damage associated with urban water pollution are internalized. The model also explicitly considers the investment needed to set-up wastewater system facilities. Our results indicate that savings in capacity could be achieved by adopting the proposed incentive-based mechanism that characterizes the optimal capacity selection rule.
