The Trade Enhancing Effect of the Free Trade Agreement and Tariff Margin : Evidence from Thailand
Keywords:
Free Trade Agreement, Global Production Network, Gravity Equation, ThailandAbstract
This paper examines the trade enhancing effect from FTA, using Thailand as a case study. A gravity equation model, the popular trade model workhorse, is applied during the period between 1991 and 2010 with allowing export and import to perform differently to the preferential trade scheme. The novel feature of the paper is that actual tariff margin, the gap between MFN and preferential-FTA rates, is calculated to measure the effect from FTAs, instead of using zero-one dummy variable. In addition, the estimate of costs in complying rules of origin is included in the calculation. Also, Products are further disaggregated into manufacturing and machinery and transport equipment (SITC 7) to examine possible different impact of FTAs. Our key finding is how to measure FTA effect matters to the outcome. Zero-one dummy variable tends to overestimate trade enhancing effect. In addition, products under production network dominated by parts and components are less likely to utilize preferential trade scheme due to the already low tariff margin. Our result raises the policy awareness in maximizing a number of FTAs. Rather its trade enhancing effect depends on FTA partners and the nature of bilateral trade between them.
