Recent years have witnessed significant transformations in the nature of policy and politics. These changes have challenged perceptions about the ways in which policy is studied, designed, delivered, and appraised. This book--originally published as a special issue of the journal Policy & Politics and the first in Policy Press's New Perspectives in Policy and Politics series--brings together leading scholars to reflect on the implications of these developments for the field of policy studies and the world of policy practice. Offering critical reflections on the recent history and future direction of policy studies, it advances crucial debates by rethinking the ways in which scholars and students of policy studies can engage with the issues in pursuit of both scholarly excellence and practical solutions to global policy problems.
