The Discriminatory Nature of Specific Tariffs
量化了欧盟特定关税对贫穷国家的歧视性影响，发现其抵消了优惠关税带来的福利收益，尤其对撒哈拉以南非洲国家农业出口的损害超过优惠关税收益的一半。
This paper quantifies the distortions from specific tariffs levied by the EU. The mostfavored-nation (MFN) specific tariffs levied by the EU translate into higher tariff barriers for poor countries exporting low price goods. We show that for poor countries, these higher tariff barriers from specific tariffs offset the gains from preferential tariffs. We apply a two-stage analysis to show that the specific tariffs levied by the EU on its agricultural imports wash away more than half of the welfare benefits enjoyed by the Sub-Saharan African countries from EU preferential tariffs. Our results provide the first quantitative estimate of the distortions associated with specific tariffs.
