摘要翻译：
我们分析了跨界污染外部性在空间和有限时间范围内对环境政策制定的影响。本文研究了一个简单的区域最优污染控制问题，比较了在单个地方决策者确定最优政策时，分别考虑和不考虑跨界外部性的全局解和局部解。我们表明局部解是次优的，因此有效地需要对环境问题采取全局方法。我们的结论适用于不同的框架，包括空间域有界或无界的情况，以及考虑宏观经济-环境反馈效应的情况。我们还表明，如果每个地方经济都实施足够严格的环境政策，那么全球平均污染水平将会下降。如果是这样的话，从长远来看，整个全球经济将能够达到完全无污染的状态。

英文摘要：
We analyze the implications of transboundary pollution externalities on environmental policymaking in a spatial and finite time horizon setting. We focus on a simple regional optimal pollution control problem in order to compare the global and local solutions in which, respectively, the transboundary externality is and is not taken into account in the determination of the optimal policy by individual local policymakers. We show that the local solution is suboptimal and as such a global approach to environmental problems is effectively needed. Our conclusions hold true in different frameworks, including situations in which the spatial domain is either bounded or unbounded, and situations in which macroeconomic-environmental feedback effects are taken into account. We also show that if every local economy implements an environmental policy stringent enough, then the global average level of pollution will fall. If this is the case, over the long run the entire global economy will be able to achieve a completely pollution-free status.
