This book provides innovative insights into one of the most controversial and important subjects of the 21st century: migration and social integration. Empirically, the volume offers comprehensive grounding in the relationships between migration, migration policies and social protection/inclusion in the enlarged European Union and its member states. Theoretically, the collection moves the debate on migration and integration policies onto new terrain. It explains how policies in this field are produced by institutional frameworks, political strategy, and contingent responses to events, but that these are themselves shaped by emotions, discourses, narratives, formal and informal aspects of governance. With contributions from leading international experts, the book can be used by academics and professionals as well as by undergraduate and postgraduate students.
