'This latest work emerging out of the prodigious Bremen School of State Transformation shows that state borders do not disappear in an age of globalization. Instead, borders become more selective, open to a courted few, but closed to the vast majority of humankind. With theoretical sophistication and methodological rigor, this excellent book shows better than any other book I know how states control mobility in our fast-changing world.' - Christian Joppke, Professor, University of Bern, Switzerland 'A fresh and innovative comparative perspective with historical depth, this accessible book builds upon the-state-of-the-art to ask key questions about state borders in the OECD world today: who is excluded by these 'semi-permeable filters,' why, how and by whom?' - Virginie Guiraudon, Research Professor, Sciences Po Center for European Studies, Paris, France
