The purpose of this series is to publish the most innovative and up-to-date research into the values and concepts that underlie major aspects of public policy. Hitherto most research in this field has been empirical. This series is primarily conceptual and normative: that is to say it investigates the structure of arguments, and the nature of values relevant to the formation, justification, and criticism of public policy. At the same time it is informed by empirical considerations, addressing specific issues, general policy concerns, and the methods of policy analysis and their applications. The books in this series are inherently interdisciplinary, and include anthologies as well as monographs. They will be of particular interest to philosophers, political and social scientists, economists, policy analysts, and those involved in public administration and environmental policy.
