Behavioural change has become a core issue of public policy in recent years. This comprehensive Handbook takes a multidisciplinary approach to examine the relationship between the two, exploring the ever-increasing analysis of behavioural change and the importance of 'nudge' in terms of public policy. Uniting interdisciplinary scholarship, Holger Strassheim and Silke Beck have drawn together a wide variety of perspectives, allowing for the legal, political, economic and social aspects of behavioural change and public policy to be explored. Contributions by renowned experts critically assess the theories and conceptual developments from early experiments to recent strategies of behavioural public policy. Chapters also cover the proliferation and professionalization of these strategies in Europe and beyond, the application of behavioural insights and instruments across areas including health, sustainability, employment, pensions, development and taxation, and the normative ideas and political consequences of knowing and governing behaviour. Political science and public policy scholars will find the inclusion of both critical and theory-driven research a vital tool, while policy-makers will appreciate the practical suggestions included in this Handbook.
