"Graeme Boushey shows us that policy diffusion processes are often characterized by 'policy outbreaks' of rapid mimicking, not solely the simple incremental, deliberate mechanism of 'laboratories of democracy' lore. Unlike the trial-and-error process of incremental learning, policy outbreaks are not at all reassuring; they are disruptive and potentially sub-optimal. Boushey demonstrates with a new dataset on policy adoptions in the states that such outbreaks occur (along with the standard incremental adoptions), and proposes a new approach based on epidemiological models of the spread of disease. This is a critically important and potentially path-breaking book."

"With its innovative theoretical framework and impressive empirical scope, Policy Diffusion Dynamics in America sheds new light on the complex political process through which ideas and policies spread from state to state. It asks the big, important questions that are sometimes neglected in contemporary diffusion research, and its well-executed and wide-ranging comparative analysis boldly challenges conventional portrayals of the diffusion process. This is an important book that will have a major impact on future scholarship."

"This is a path-breaking study that advances both theory and research in policy diffusion, and will be cited extensively for its contributions. One of the dilemmas of diffusion research has been how to develop more generalizable theory beyond studies of discrete policy innovations. Boushey examines a wide variety of policy issues, but he does much more in building theory, identifying distinct patterns across policy types and firmly embedding them in more general theories of agenda-setting and policy change. This book will change our thinking and research on policy diffusion."

"Combining theories of punctuated equilibrium and policy diffusion, Graeme Boushey creates a compelling new account of policymaking in American federalism. The nature of the policies themselves, their targets, and their advocates dictate the dynamics by which innovative policy spread across the states. Boushey's focus on the speed and scope of diffusion will guide scholars of American and comparative politics, as well as those outside of political science."
