Regulatory economics has become increasingly important over the last quarter of a century, in part as a result of the wave of privatization, starting in the UK, which made the regulation of monopoly of much greater interest. The discipline has also become more rigorous, increasingly employing powerful analytical and econometric methods. This volume brings together some of the leading contributions to the literature on this subject. The book is an invaluable resource for scholars, policymakers and regulators in the study of privatization and regulation.
