"International trade has been cited as a source of widening wage inequality in industrial nations. Most previous empirical evidence supports this claim by showing an effect in which increasing exports tilt demand towards firms which export and employ a relatively large proportion of higher-skilled workers from the group of firms which do not export. We find that, in addition to this, there is also an effect whereby, among exporting firms, there is a significant wage premium for high-skilled workers and a wage discount for low-skilled workers. These estimates are based on a matched employer–employee data set of western German manufacturing firms over the period 1993–2007. Our estimates suggest that export activity can be associated with up to 30% of within and between skill group wage inequality."

"We set up a general equilibrium model, in which offshoring to a low-wage country can lead to job polarisation in the high-wage country. Job polarisation is the result of a reallocation of labour across firms that differ in productivity and pay wages that are positively linked to their profits by a rent-sharing mechanism. Offshoring involves fixed and task-specific variable costs, and as a consequence it is chosen only by the most productive firms, and only for those tasks with the lowest variable offshoring costs. A reduction in those variable costs increases offshoring at the intensive and at the extensive margin, with domestic employment shifted from the newly offshoring firms in the middle of the productivity distribution to firms at the tails of this distribution, paying either very low or very high wages. We also study how the reallocation of labour across firms affects economy-wide unemployment. Offshoring reduces unemployment when it is confined to high-productivity firms, while this outcome is not guaranteed when offshoring is also chosen by low-productivity firms."
