The influx of migrant workers from Central and Eastern Europe over the last decade represents the largest migratory flows to Norway in history and an unprecedented supply shock to parts of the Norwegian labour market. This article reviews existing research and summarises the findings in terms of (1) the volume, direction and temporal patterns of migration flows; (2) the economic integration of new labour migrants; (3) the impacts of labour migration on wages, employment, skills, and social organisation of work in affected industries and (4) the political and institutional responses to rising labour migration. The article concludes by discussing the overall long-term consequences of labour migration, particularly with regard to social inequality in Norway.
