Within the framework of the 17th European Regional ITS Conference, session on the Next Generation Infrastructure (see programme)C.B. Blankart, G. Knieps, and P. Zenhäusern presented their new paper on "Regulation of New Markets in Telecommunications? Market Dynamics and Shrinking Monopolistic Bottlenecks".
In the paper the Authors focuse on the debate on the EU telecommunications regulatory framework and analyse whether new markets create new monopolistic bottlenecks or extend the borderlines of existing bottlenecks. Three kinds of transmission qualities on service markets can be dif-ferentiated according to the products provided: narrowband services like PSTN/ISDN or GSM, semi high-speed broadband services like broadband inter-net access up to 6 Mbps download and VDSL services up to 50 Mbps. As long as, due to the absence of alternative network infrastructures, a monopolistic bot-tleneck in local infrastructure networks exists the question arises what the re-maining bottleneck components are for these different markets. In this paper we will demonstrate the shrinking-bottleneck hypothesis.
