本文讨论了国内环境政策对外国排放和跨界污染的影响。我们使用了一个迪克西特-斯蒂格利茨型的垄断竞争模型，企业的数量是内生的，生产产生了环境外部性，这些外部性会溢出到其他国家。研究表明，环境政策对国内外市场结构都有影响。这些市场结构效应导致国外排放量的变化。与早先的研究成果相反，国内更严格的环保标准有可能导致国外更少的排放。本文导出了这些结果，并提供了它们背后的经济学直觉。最后，最优环境政策的条件。
The paper discusses effects of domestic environmental policy on foreignemissions and on transboundary pollution. We use a Dixit-Stiglitz typemodel of monopolistic competition with an endogenous number of firms.Production generates environmental externalities which spill over to theother country. It is shown that environmental policy has an impact onmarket structure at home and abroad. These market structure effectsinduce changes in emissions abroad. In contrast to what has been derivedin earlier contributions, it turns out to be possible that tighterenvironmental standards at home lead to less emissions abroad. The paperderives these results and provides the economic intuition behind them.Finally, conditions for optimal environmental policies are derived.
