Access prices are important for competition in formerly monopolistic industries, and also for industries where competition has long been established such as payment and credit card networks or mobile telecommunications. Organized into five parts, this book provides theoretical and empirical analyses in access pricing and related topics.

Parts IV and V address the practice side and focus on industry-specific applications and special problems (Part IV) as well as public policy issues (Part V). This book provides valuable theoretical and empirical analyses in Access Pricing and related topics. It offers several different points of view. It features research from highly reputed scientists working in this field.
