We develop a two–country model of foreign aid and cross–border pollution resulting from production activities in the recipient country. There is both private and public abatement of pollution, the latter being financed through emissions tax revenue and foreign aid. We characterize a Nash equilibrium in which the donor country chooses the amount of aid and the recipient chooses the fraction of aid allocated to pollution abatement and the emission tax rate. At this equilibrium, an increase in the donor's perceived rate of cross–border pollution reduces emission levels. JEL Classification: Q28, F35, H41 Est–ce que la pollution trans–frontière peut réduire le niveau de pollution? Les auteurs développent un modèle à deux pays d'aide à l'étranger et de pollution trans–frontière résultant d'activités de production dans le pays qui reçoit l'aide. Il existe des efforts privés et publics pour réduire la pollution, ces derniers étant financés par les rentrées fiscales d'une taxe sur la pollution et par l'aide étrangère. On définit un équilibre à la Nash pour lequel le pays donateur choisit le montant de l'aide, et le pays récipiendaire choisit la fraction de l'aide étrangère qu'il allouera à la lutte à la pollution ainsi que le taux de taxation sur la pollution. A cet équilibre, un accroissement dans le taux de pollution trans–frontière perçu par le donataire réduit le taux de pollution.

We construct a two-good general equilibrium model of international trade for two small open economies where pollution from production is transmitted across borders. Governments in both countries impose emission taxes non-cooperatively. Within this framework, we examine the effect of trade liberalization and of changes in the perception of cross-border pollution on Nash emission taxes, emission levels, and welfare.

We consider a two small open economies model with cross-border pollution that is generated from consumption. Within this framework we examine i) the non-cooperative equilibrium consumption taxes and compare them to when pollution is only local, ii) the cooperative equilibrium consumption taxes and we compare them to the non-cooperative tax rates, and iii) cases where cooperative taxes are different between countries. In this framework, tax harmonization may not be the optimal policy if, for example, pollution per unit of consumption differ between countries. Many results of the paper depend on the relationship in consumption (i.e., complementarity or substitutability) between pollution and the polluting good.
