Book excerpt: This comprehensive book provides a unique comparative policy analysis of public-private partnerships (PPPs) in 14 Western European countries – from Scandinavia to Greece – bringing together important insights from government and politics as well as economics and institutional analysis. Thomas Krumm focuses on political drivers for policy change in favour of PPPs, and the supportive and limiting socioeconomic and institutional conditions. Using comparative data, he charts key policies and actors involved in supporting collaboration between the State and private business organisations across Western Europe. Students and scholars of public policy, regulation and comparative politics, among other disciplines, will find this book to be useful in their research or teaching. It will also be of substantial interest to PPP practitioners, and other specialists in the subject.
