In this book, Russell Prince skilfully illuminates the core value of studying policy mobilities: to understand policy making through diverse power relations, political settlements, and relational engagements with spatial practices. He demonstrates how policies are always emergent from a range of territorialised experimentation, yet they are never only local, intersecting with wider processes of world-building and policy infrastructures to influence and create diverse outcomes across places. -- Cristina Temenos, University of Manchester, UK Understanding Policy Mobility is a concise and clearly argued guide to the critical literature on global-relational policymaking. Thoughtful, incisive, and clear, the book suggests how to think about policy mobility as a socio-spatial and political process. It is an essential starting point for those interested in policy-makings role in world-making. -- Eugene McCann, Simon Fraser University, Canada With great clarity and insight, Russell Princes Understanding Policy Mobility not only explains why and how public policy ideas move, but why it matters. An indispensable guide through decades of scholarship, Prince compellingly argues that when policy moves, the world moves with it. -- Tom Baker, University of Auckland, New Zealand
