Inequality and Unemployment in a Global Economy
构建了一个新框架，强调行业内重新配置、劳动力市场摩擦和企业间劳动力构成差异，研究贸易如何影响工资不平等和失业。
This paper develops a new framework for examining the determinants of wage distributions that emphasizes within-industry reallocation, labor market frictions, and differences in workforce composition across firms. More productive firms pay higher wages and exporting increases the wage paid by a firm with a given productivity. The opening of trade enhances wage inequality and can either raise or reduce unemployment. While wage inequality is higher in a trade equilibrium than in autarky, gradual trade liberalization first increases and later decreases inequality.
