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.

This article investigates the effects of homeownership on labour mobility and unemployment duration. We distinguish between finding employment locally or being geographically mobile. We find that homeownership hampers the propensity to move for job reasons, but improves the chances of finding local jobs, which is in accordance with the predictions from our theoretical model. The overall hazard rate into employment is higher for homeowners, such that there is a negative correlation between homeownership and unemployment duration. Our empirical findings thus contradict the so-called Oswald hypothesis, even if support is found for the main mechanism behind the hypothesis, namely that homeownership hampers mobility.

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 track the outcomes for workers after a job spell and find that those displaced from offshoring firms suffer greater earnings losses than other displaced workers, and that low-skilled workers suffer greater and more persistent earnings losses than high-skilled workers.

This paper studies the link between a …rms education level, export performance and wages of its workers. We argue that …rms may escape intense competition in international markets by using high skilled workers to di¤erentiate their products. This story is consistent with our empirical results. Using a very rich matched worker…rm longitudinal dataset we …nd that …rms with high export intensities pay higher wages. However, an interaction term between export intensity and skill intensity has a positive impact on wages and it absorbs the direct e¤ect of the export intensity. That is, we …nd an export wage premium, but it accrues to workers in …rms with high skill intensities.

Most countries promote exports. This paper answers two questions: Does export promotion improve firm performance, and do any benefits outweigh costs? We solve self-selection problems by accounting for an extensive set of firm characteristics. In addition, we distinguish firms that self-selected into promotion services from firms the Danish Trade Council approached based on observed information. We find that export promotion increases sales, value added, employment, and value added per worker. For small firms, summing expenditures on export promotion, subsidies, and tax distortions, the gain in value added is roughly three times higher than the direct costs of export promotion.
