"By merging longitudinal register data and a customised survey, this article explores whether sectoral segmentation, migrants' pre- and post-migration human capital and social structures, shape wages of Polish and Romanian long-term migrants to Denmark. Pronounced wage differences in favour of Polish migrants are evident in the first two years in Denmark, notwithstanding the same regulatory context under the free movement of labour in the EU. Wage differences persist – albeit at a considerably lower level – throughout the eight-year period, mainly because of significant sectoral segmentation. Sectoral segmentation not explained by demographics, premigration human capital or crisis effects, might indicate categorical stereotyping by employers. Regarding (co-ethnic) social networks, at least for the early stages of migration, the study does not find significant effects on wages. While the evidence shows a positive return on wages of formal higher education taken post migration, this is not the case for further training and Danish language education."
