High-Skill Migration and Agglomeration. William Kerr, 2017, Paper, “This review considers recent research regarding high-skilled migration. We adopt a data-driven perspective, bringing together and describing several ongoing research streams that range from the construction of global migration databases, to the legal codification of national policies regarding high-skilled migration, to the analysis of patent data regarding cross-border inventor movements. A common theme throughout this research is the importance of agglomeration economies for explaining high-skilled migration. We highlight some key recent findings and outline major gaps that we hope will be tackled soon.Link
