Importing Skill-Biased Technology
研究了资本设备进口如何通过资本-技能互补性影响技能溢价，提供了量化方法并应用于多国数据。
The production of capital equipment is concentrated among a small group of countries, and many countries import a large share of their equipment. If capital-skill complementarity is an important feature of technology, international trade may have important effects on the skill premium through its impact on equipment accumulation. In this paper we propose a tractable framework for evaluating this effect, provide simple analytic expressions linking observable changes in import shares by sector to changes in real wages of skilled and unskilled workers (and, therefore, the skill premium), and quantify the importance of this effect for a large set of countries.
