题目：Integrated Analysis of the Effect of the Free Trade Agreement on Multilateral Trade Liberalization
摘要：Does formation of a Free Trade Agreement (FTA） lead to more or less protectionist trade policies towards nonmember countries? This paper builds on existing theoretical literature of FTAs to identify key channels through which preferential tariff reductions towards one group of countries may lead to either increased or reduced tariffs towards other countries. We develop a novel empirical strategy to identify the causal effect of FTAs on external tariffs of their members and estimate both channels using a sample that covers most FTAs formed since the 1990s. We find that countries tend to reduce their tariffs following FTA formation. Specifically, our results indicate that for an average industry and a pair of FTA partner countries, a one percentage point reduction in FTA tariff leads to 0.012-0.017 percentage points decrease in the MFN tariff. The effect is relatively small because most FTAs are between countries with small bilateral trade flows, but it is substantially larger for FTAs between main trade partners. For example, the mean elasticity of the MFN tariff with respect to the preferential tariff for the CanadaU.S. Free Trade Agreement is in the range of 0.2-0.25. Our findings support the idea that FTA formation provides member countries with economic incentives to liberalize their trade policies.
