Migration and the Externalities of European Integration analyzes the extra-European dimension of the European Union’s migration policies and the mechanisms developed to enforce the EU’s policy decisions. While previous scholarship has tended to overlook the consequences of Europeanization on actors outside the EU, this work scrutinizes the foreign policy dimension in EU migration policies and highlights the Union’s complex role as an international actor. Written by scholars of migration policy, the essays discuss the impact of EU asylum and refugee policy on Norway, Switzerland, Eastern Europe, and the Euro-Mediterranean region and the effect of migration on European immigration controls and welfare policy. This comprehensive treatment of transnational migration will be a valuable resource for students of international affairs, European integration, and international organization.
