Significant Market Power in Telecommunications: Theoretical and Practical Aspects
From an economic perspective efficiency and innovation are crucial aspects of functional competition in telecommunications where one has to take into account sector specific problems. Besides those specific aspects we consider the topic of significant market power and its evolution. As a special problem we focus on product bundling issues and aspects of network dynamics. As regards policy conclusions there is need for differentiated approaches. We emphasize the need for a dynamic perspective of competition in telecommunications markets. With respect to oligopolistic markets we present as a theoretically new approach an application of the Hitch-Sweezy model of competition - the implication is that (price)regulation should be restricted to a very small field.
