Abstract

This thesis discusses the role of sector-specific regulators in the rapidly changing telecommunications industry. In particular, it studies the access pricing policy which provides the optimal balance between static and dynamic efficiency that better reflects the changing regulatory goals in a highly variable economic and technological environment. Static efficiency concerns the maximization of social welfare by intensifying the competition for providing differentiated services (service-based competition), whereas dynamic efficiency concerns the maximization of social welfare by incentivizing investments in competitive infrastructures (facilities-based competition). It is thus obvious that the role of regulators is to facilitate the gradual transition from static to dynamic efficiency by influencing the investment and competition outcomes through the regulation of the access price. Therefore, there is an interplay between regulatory policy and technological development which leads to rapidly changing market structures and industry performance.
