Trade Liberalization and the Skill Premium: A Local Labor Markets Approach
构建了一个包含技能和非技能工人的区域经济特定要素模型，并用巴西1990年代初的贸易自由化数据检验，发现自由化对1991-2010年间技能溢价变化有统计显著但温和的影响。该方法适用于其他国家和自由化事件。
We develop a specific-factors model of regional economies that includes two types of workers, skilled and unskilled. The model delivers a simple equation relating trade-induced local shocks to changes in local skill premia. We apply the methodology to Brazil's early 1990s trade liberalization and find statistically significant but modest effects of liberalization on the evolution of the skill premium between 1991 and 2010. The methodology uses widely available household survey data and can easily be applied to other countries and liberalization episodes.
