'One of the first collections of empirical studies on the international experience with public-private partnerships (PPPs), The Challenge of Public-Private Partnerships raises several crucial issues that challenge the effectiveness of PPPs. It does a good job of organizing scattered research on a complicated topic, examining partnerships in historical, political, and economic contexts, and pointing out major defects in previous studies. The editors have assembled an all-star cast of contributors to accomplish three major goals relating to PPPs: to reexamine the huge range of definitions, to review the international experience and learn from the outcomes, and to call for more careful balanced assessment.'
