This study analyzes aggregate data on trade flows to examine the performance of bilateral free trade agreements (BFTAs) between the United States and 11 BFTA nations in a two-dimensional approach. In line with the literature, this study applies the gravity model and analyzes the effect of the treatment using Poisson pseudo-maximum likelihood (PPML) panel data from 1992 to 2017. We use the PPML as an alternative methodology to an ordinary least squares model, as it can treat zero trade values and lead to unbiased estimates and different consistencies. We consider the trade in goods but excluded services because of the different nature of trade for services. Moreover, this study highlights the quantitative performance of BFTAs without considering the industry level to compare the overall benefits for the trade flows from the U.S. as an exporter to BFTA countries and vice versa. It thus adds to the debate on the effect of FTAs on trade flows and conducts pre-FTA and post-FTA analyses to compare the volumes of exports and imports during both periods. Findings vary according to the direction of trade; notably, some trading partners increased their trading volume to 388%. In sum, this paper provides a collective current state assessment to demonstrate the most plausible reasons for the effects of the 11 BFTAs, in addition to informing policymakers on the lessons learned from each BFTA.
本研究通过二维方法分析了美国与 11 个自由贸易协定国家之间的贸易流量综合数据,以检验双边自由贸易协定 (BFTAs) 的绩效。本研究遵循文献,应用引力模型,并使用 1992 年至 2017 年的泊松伪极大似然 (PPML) 面板数据分析处理的影响。我们使用 PPML 作为普通最小二乘法模型的替代方法,因为它可以处理零贸易值,并导致无偏估计和不同的一致性。我们考虑了商品贸易,但排除了服务业,因为服务业的贸易性质不同。此外,本研究强调了 BFTAs 的定量绩效,而不考虑行业层面,以比较美国作为出口国向 BFTAs 国家和反之的贸易流量的总体利益。因此,它增加了关于自由贸易协定对贸易流动影响的辩论,并进行了自由贸易协定前和自由贸易协定后的分析,以比较这两个时期的出口和进口量。研究结果因贸易方向而异;值得注意的是,一些贸易伙伴的交易量增加了 388%。总之,本文提供了一个集体的现状评估,以展示 11 个自由贸易协定影响的最可能原因,此外还为决策者提供了从每个自由贸易协定中吸取的经验教训。
