Abstract: This paper uses a two-country dynamic general equilibrium model to consider how, following a trade cost shock, multinational firms’ offshoring decision and the countries’ different factor endowments affect wage inequality between high- and low-skilled workers in the home country. Highlighting task-offshoring, heterogeneous firms, and factor proportions, the study sheds light on how offshoring shapes wage inequality along different time horizons. While the paper’s focus is the relationship between the U.S. (home country) and China (foreign country), its findings are more broadly relevant. The three main findings are these: First, both intensive and extensive margins of offshoring contribute to the widening wage gap, with the latter playing a more important role in the medium run than it does in the initial stage after the trade cost shock. Second, endogenous firm entry raises wages for both high-skilled and low-skilled workers while narrowing the wage gap between the two groups over time. Third, whether firms offshore to a foreign country like Mexico, where the supply of low-skilled laborers is moderately larger than in the home country, or to a country like China, where the supply of low-skilled laborers is vastly larger, makes scant difference to wage inequality in the long run. However, the latter is more beneficial to firm entry, product variety, and consumption.
