'The field of policy studies has long been characterized by rather narrow empirical perspectives. In more recent years, however, there has been a flurry of theoretical orientations that have sought to reorient the field in ways that speak to contemporary policy realities. By focusing on the differences and intersections between four competing perspectives - rational, political, institutional, and cultural - Public Policy in Action offers a useful framework that helps to move the field forward.'--Frank Fischer, Humboldt Universitat zu Berlin, Germany
