This book explores the wave of liberalization reforms experienced by OECD network industries. Focusing on the telecommunications sector, the authors analyze the latest data available on liberalization and privatization, and following a political economics approach, they integrate standard economic analysis with the most recent studies of the political determinants of market-oriented policies. The book presents new econometric evidence on several policy issues, including institutional complementarities dynamics, the problem of policy sequencing and the role of government political ideology. The detailed and comprehensive discussion offers insights into how so many countries adopting similar reforms actually differ in their policy bundling, intensity and implementation of liberalization and privatization.
