Title

Two-Way Outsourcing, International Migration, and Wage Inequality

Abstract

This paper develops a general equilibrium model with a vertical production structure to examine the relationship between offshore outsourcing and international migration,especially emphasizing their effects on the wages of skilled and unskilled workers. Two-way outsourcing (simultaneous insourcing and outsourcing) in skilled-labor intensive services arises due to product differentiation and scale economies, and outsourcing in unskilled-labor intensive processing occurs because of factor endowment differences. The tractability of the model allows us to rank outsourcing and migration, according to the wages of both types of workers. Finally, we also analyze under what conditions outsourcing and international migration are complements or substitutes.
