Book excerpt: Dialogues on Migration Policy brings together leading American and European scholars of immigration politics to address migration policy. Editors Marco Giugni and Florence Passy's aim to present a number of informed 'dialogues' addressing three main theoretical concerns in this field: the role of the national state in a globalizing world, the determinants of policy change, and the role of collective interests in migration policy. Adopting an unconventional format, the novelty of Dialogues on Migration Policy lies in the fact that it is structured around a series of debates among authors. In each debate, expert contributors working in different theoretical traditions and with divergent views on the subject matter confront each other followed by a commentary from a leading scholar based on her/his reading of these authors' views. These lively debates are certain to engage scholars of migration, political science, and sociology.
