We estimate how offshoring (and exporting) affect wages by skill type. Our data match the population of Danish workers to the universe of private-sector Danish firms, whose trade flows are broken down by product and origin and destination countries.
Our data reveal new stylized facts about offshoring activities at the firm level, and allow us to both condition our identification on within-job-spell changes and construct instruments for offshoring and exporting that are time varying and uncorrelated with the wage setting of the firm.  We find that within job spells, (1) offshoring tends to increase the high-skilled wage and decrease the low-skilled wage; (2) exporting tends to increase the wages of all skill types; (3) the net wage effect of trade varies substantially across workers of the same skill type; and (4) conditional on skill, the wage effect of offshoring exhibits additional variation depending on task characteristics.  
We then construct worker cohorts prior to offshoring shocks and track cohort members consistently over time to capture the overall effect of offshoring, both in within-job-spell wages and displacement, on workers’ present and future income streams.
The paper "The Wage Effects of International Offshoring: Evidence from Danish Matched Worker-Firm Data" is joint work with David Hummels and Chong Xiang, Purdue University.
