Firm Heterogeneity, Trade, and Wage Inequality

Author

Abstract

This paper considers a world of two symmetric countries with two factors and two sectors. Outputs of the two sectors are imperfect substitutes and sectors differ in relative factor inten- sity. Each sector contains a continuum of heterogenous firms that produce differentiated goods within their sector. Trade is costly and there are both variable and fixed costs of exporting. The paper shows that under some plausible conditions supported by the data, trade between similar countries can increase the demand for skilled labor, which in turn increases the wage inequality between skilled and unskilled labor. The quantitative analyses suggest that such trade effects can explain up to 12 percent of the increase in the US skill premium.
