Book excerpt: The world of public policy is becoming increasingly small due to dramatic changes in global communications, political and economic institutional structures, and to nation states themselves. This book evaluates the implications of these changes and challenges for both the study and the practice of policy transfer, and provides a unique understanding of the relationship between systemic globalizing forces and the increasing scope and intensity of policy transfer activity. It provides: an explanation of policy transfer as a process of organizational learning; an insight into how and why such processes are studied by policy scientists; an evaluation of its use by policy practitioners; and the first published collection of policy transfer case studies between developed countries, from developed to developing countries, and from developing countries.
