This study empirically examines how trade liberalization changes individuals' wages, with evidence from Thailand. We primarily focus on the effect of Thailand's tariff reduction under the ASEAN free trade regime. We use individual-level employment data for 2001, 2006, 2011, and 2016. We find that the reduction in AFTA tariffs in Thailand decreases the relative wages of the more educated and skilled workers. Thus, trade liberalization contributes to narrowing income inequality in terms of education and skills. Contrastingly, we do not find heterogeneous effects according to age, sex, marital status, location, or company size. Moreover, the results do not differ significantly between industries with or without international competitiveness.

贸易自由化对个人工资的异质影响：来自泰国的证据

本研究以泰国的证据为依据，实证检验了贸易自由化如何改变个人工资。我们主要关注东盟自由贸易体制下泰国关税减免的效果。我们使用 2001 年、2006 年、2011 年和 2016 年的个人就业数据。我们发现泰国 AFTA 关税的降低降低了受教育程度和技术水平较高的工人的相对工资。因此，贸易自由化有助于缩小教育和技能方面的收入不平等。相比之下，我们没有发现年龄、性别、婚姻状况、地点或公司规模不同的异质效应。此外，具有或不具有国际竞争力的行业之间的结果并没有显着差异。
