Policy-making is more globally connected than ever before. Policy ideas, experiences and expertise circulate with great speed and over great distances. But who is involved in moving policy, how do they do it, and through which arenas? This book examines the work involved in policy circulation. As the first genuinely interdisciplinary collection on policy circulation, the book showcases theoretical approaches from across the social sciences—including policy diffusion, transfer and mobility—and offers empirical perspectives from across the world.
