This paper analyzes environmental concerns by a government in a setting of rent-extracting strategic trade policy with endogenous firm investment into production technologies. The simple analysis reinforces the importance of investment incentives caused by tariffs in general and shows that the resulting implications for the optimal tariff decision can be completely different between traditional tariff considerations and an environmentally conscious government. We show that an importing country in a dynamic setting with endogenous firm technology choices prefers to impose discriminatory tariffs both ex post and ex ante when emissions matter, while—as previously found in the literature—a commitment to uniform tariffs is optimally chosen when environmental concerns do not play a role.

最优关税和企业技术选择：一种环境方法

本文分析了政府对环境问题的关注，即在提取租金的战略贸易政策以及对生产技术的内生企业投资的情况下。简单的分析强调了一般关税引起的投资激励的重要性，并表明传统关税考虑和具有环保意识的政府对最优关税决策的影响可能完全不同。我们表明，在具有内生企业技术选择的动态环境中，进口国更愿意在排放很重要的情况下在事后和事前征收歧视性关税，而正如先前在文献中发现的那样，当环境问题时，最佳选择统一关税的承诺不发挥作用。
