This book is based upon a comparative public administration research project, initiated by the Hertie School of Governance (Germany) and the Bertelsmann Foundation (Germany) and supported by a network of researchers from many EU countries. It analyzes both the regimes and the practices of local fiscal regulation in 21 European countries. The book brings together key findings of this research project. The regulatory discussion is not limited to the prominent issue of fiscal rules but focuses on every component of regulation. Beyond this, the book covers affiliated topics such as the impact of regulation for local governments, evolution of regulation, administrative costs and crisis prevention. The various book chapters throughout provide a broad picture of local public finance regulation in theory and in practice, using different theoretical and national lenses for the analysis. Furthermore, the authors investigate the effects of budgetary constraints and higher-level regulatory efforts on local governments and on democracy and public services in every European country. This book fills a gap with respect to the lack of discussion on local government finance from an international, comparative perspective and, in particular, the regulation of local public finance. With its mix of authors, this book will be useful for practitioners as well as for scholars and for theory-driven research.
