Offshoring of production can have a deep impact on the wages and welfare of workers with different abilities through its effect on technological progress. This column argues that, when labour is sufficiently cheap abroad, firms have incentives to offshore low-skill tasks and invest in skill-biased technologies at home. Over time, however, offshoring raises foreign wages. This increases demand for all firms and makes innovations complementing low-skill workers more profitable. As a result, offshoring can eventually lead to higher wages for everybody and less inequality.
