摘要

We employ data that match the population of Danish workers to the universe of private-sector Danish firms, with product-level trade flows by origin-and destination-countries. We document new stylized facts about offshoring and instrument for offshoring and exporting. Within job spells, offshoring increases (decreases) the high-skilled (low-skilled) wage; exporting increases the wages of all skill-types; the net wage-effect of trade varies substantially within the same skill-type; conditional on skill, the wage-effect of offshoring varies across task characteristics. We estimate the overall effects of offshoring on workers' present and future income streams by constructing pre-offshoring-shock worker-cohorts and tracking them over time.
