This book explores how policy ideas are spread—or diffused—in an age in which policymaking has become increasingly complex and specialized. Using the concept of enterprise zones as a case study in policy diffusion, Karen Mossberger compares the process of their adoption in Virginia, Indiana, Michigan, New York, and Massachusetts over a twelve-year period. Enterprise zones were first proposed by the Reagan administration as a supply-side effort to reenergize inner cities, and they were eventually embraced by liberals and conservatives alike. They are a compelling example of a policy idea that spread and evolved rapidly. Mossberger describes the information networks and decisionmaking processes in the five states, assessing whether enterprise zones spread opportunistically, as a mere fad, or whether well-informed deliberation preceded their adoption.

Using the spread of enterprise zones as a case study, this book explores how policy ideas are diffused amongst states. Taking the adoption of such zones, a way of regenerating the inner cities, the book traces the decision making process through five states.

Enterprise zones have been part of American urban policy for over 20 years. In this book, the authors (urban and regional planning, the University of Iowa) use a hypothetical firm methodology to measure the value of enterprise zone incentives to business, involving construction of a set of financial statements for typical firms and application of tax code and incentives to those firms. They briefly discuss this model (with technical information on the model included in an appendix), and look at the results of enterprise zone programs in place in 13 states.
