In recent decades, all infrastructures have undergone significant restructuring. This worldwide phenomenon is often labelled 'liberalization' and although expectations were high with respect to lower prices, greater efficiency and innovation, the expected gains have not always been fully realized. This extensive, state-of-the-art Handbook provides a comprehensive overview of the various experiences of liberalization across different sectors, regions and disciplines. The multidisciplinary approach focuses on the economic, political and institutional aspects of liberalization, as well as to a lesser extent on technological issues. As such, it constitutes a unique contribution as this broad overview is often lost in the sector specific, country-focused and purely disciplinary approaches prevalent in the current literature. Sectors explored include telecoms, the Internet, energy and transport, while the truly global perspective incorporates unique case studies from an array of developed and developing countries including the US, China, India and the EU.
