Global Supply Chains and Wage Inequality
扩展了Costinot、Vogel和Wang（2011）的模型，引入多要素，研究全球供应链如何影响一国内部的工资不平等。
A salient feature of globalization in recent decades is the emergence of “global supply chains” in which different countries specialize in different stages of a sequential production process. In Costinot, Vogel and Wang (2011) (CVW hereafter), we have developed a simple theory of trade with sequential production to shed light on how global supply chains affect the interdependence of nations. In this paper we develop a multi-factor extension of CVW to explore how the emergence of global supply chains may affect wage inequality within countries.
