The Cambridge Studies in Comparative Public Policy series was established to promote and disseminate comparative research in public policy. The objective of the series is to advance the understanding of public policies through the publication of the results of comparative research into the nature, dynamics and contexts of major policy challenges and responses to them. Works in the series will draw critical insights that enhance policy learning and are generalizable beyond specific policy contexts, sectors and time periods. Such works will also compare the development and application of public policy theory across institutional and cultural settings and examine how policy ideas, institutions and practices shape policies and their outcomes. Manuscripts comparing public policies in two or more cases as well as theoretically informed critical case studies which test more general theories are encouraged. Studies comparing policy development over time are also welcomed.
