This book is divided into three parts: Part I provides the theoretical background for the study of airport regulation and regulatory systems. Competition at airports is discussed, as are common forms of regulation and potential pitfalls. Part II addresses benchmarking, as benchmarking is often applied as an input to the regulatory process. Although benchmarking is necessary, reviews of how benchmarking is applied in the literature and in practice show that improvements can be made. Part III providescase studies on real-world examples. Addressing the question of whether and how European airport regulators set incentives for efficiency, and how benchmarking is used in the regulatory process, this book is an important contribution to the development of the transport industry in Europe and Latin America. It will appeal to scholars and students in transport economics, regional economics and related fields, as well as to practitioners and policy makers in the transport industry.
