Previously published as a special issue of the Journal of European Public Policy, this book draws on the insights of the existing literature on agenda setting and policy changes to explore the dynamics of attention allocation and its consequences. Attention is a crucial variable in understanding modern politics. Shifts in attention have dramatic consequences for both politics and policy decisions. This volume includes case studies of nine different political systems including the US, Canada, several European systems, and the EU itself. It asks the following questions: Which are the dynamics of agenda-setting in the EU? Which role do political parties play in attention allocation? What are the cross national differences in attention to health care? What role does science and expertise play in attention-allocation? What are the effects of political institutions? Comparative Studies of Policy Agendas will be of interest to students and scholars of policy analysis and public policy.
