| Abstract: | Abstract A differential game with N countries as players is developed for the analysis of a marine resource with open access used by the countries as a pollutant sink and for production of an ecosystem good. Consumption, investment, abatement, and environmental research sectors may differ across countries. Under the assumption that property rights are well defined within the sovereignty of each country although there is a lack of enforcement in the international area, the game is solved for the feedback Nash equilibrium, using the Isaacs–Bellman dynamic programming technique, identifying the nonlinear feedback Nash flows of consumption, investment, harvest effort, abatement, and environmental research effort in each country, which is then compared to the Pareto optimal global solution. |
