Book excerpt: Contemporary policy making is deeply influenced by the borrowing, transfer and diffusion of ideas and models from other countries, levels of government and supranational institutions. This is the first book to analyze comparatively the micro-dynamics of transfer across regions, contrasting policy fields, multiple levels of governance, and institutional actors. Grounded in original research by specialists in the field, it provides fresh and arresting insights into competition among transfer agents, resistances, local coalitions, translation, and policy learning. This empirical depth informs a reinvigorated and nuanced theoretical framework on global policy transfer processes.
