This book examines the nexus between City Networks, multilevel governance and migration policy. Examining several City Networks operating in the European Union and the United States of America’s multilevel political settings, it brings migration research into conversation with both policy studies and political science. One of the first comparative studies of City Networks and migration, the book argues that multilevel governance is the result of a contingent process of converging interests and views between leaders in network organisations and national governments, the latter continuing to play a key gatekeeping role on this topical issue even in the supranational EU system.

Tiziana Caponio is Associate Professor at the University of Turin and Fellow at Collegio Carlo Alberto, Italy. In this conceptually and empirically rich analysis, Tiziana Caponio changes the way we think about migration by focusing on cities and the important role played by city networks. By changing the focus to the city, Caponio also changes the way that we understand these issues and sets out an innovative agenda for both academic researchers and policy-makers. Andrew Geddes, Director, Migration Policy Center/EUI Caponio explores the topical issue of migration policy, and the central role that cities play in it, using the theoretical lens of multilevel and network governance and making significant strides in the understanding and conceptualization of both theoretical approaches and the necessary and sufficient conditions for their activation emphasizing the role of distinct sets of actors. The cross-Atlantic comparative approach lends wider purchase to her analysis and enriches the institutional dimension of her exploration.
