Book excerpt: This is an open access title available under the terms of a CC BY-NC-ND 4.0 International licence. It is free to read at Oxford Scholarship Online and offered as a free PDF download from OUP and selected open access locations. This book presents twenty-three in-depth case studies of successful public policies and programs in Sweden, Denmark, Finland, Norway, and Iceland. Each chapter tells the story of the policy's origins, aims, design, decision-making, and implementation processes, and assesses in which respects - programmatically, process-wise, politically, and over time - and to what extent it can be considered to have been successful. It also points towards the driving forces of success, and the challenges that have had to be overcome to achieve it. Combined, the chapters provide a resource for researchers, educators, and students of public policy both within and beyond the Nordic region.
