Fusionskontrolle in dynamischen Netzsektoren am Beispiel des Breitbandkabelsektors: zugleich ein kritischer Beitrag zur Kartellrechtsdogmatik des Bundeskartellamts nach Iesy/Ish und TC/Ish und sektorspezifischen Regulierungskonsistenz seitens der Bundesnetzagentur

The working report looks at the actual situation of the German broadband cable market in the context of merger control and sector specific regulation. A crucial problem in dealing with the cable market whether in antitrust cases or in the regulatory context is the precise assessment of the economic conditions, especially the arguable question if the network has still characteristics of a natural monopoly still a common argument in network industries. The report therefore uses the basic concept of the disaggregated identification of network-specific market power. The unique structure of the German broadband cable industry with its horizontal and vertical separation of the distribution network shows a highly contestable market with elements of competitive franchise bidding. On the other hand the cable market is suffering from that separation due to problems of inefficiency, especially in times of dynamic changes in communications with powerful intermodal competitors like Deutsche Telekom AG (DTAG) with an innovative IPTV infrastructure. To this date these market characteristics have been ignored. --Bottleneck,broadband cable,consumer surplus approach,contestable markets,disaggregated approach,efficiency analysis,essential facility,franchise bidding,market definition,market dominance,market power,merger control,network effects,open field approach,regulation,remedies and conditions,telecommunication networks,total welfare standard

A Spatial Interpretation of the Persistency of China's Provincial Inequality

China's rapid economic growth in recent decades has not led to balanced income distribution: inter- and intra-provincial income inequality have been increasing and their respective contribution to the total income inequality remains relatively stable. Based on a new set of prefectural database during a relatively longer period from 1994 to 2008 on Chinese economic development, this paper investigates the nexus between the spatial dependence and income inequality in China on a prefectural level. Using the decomposition results of the inequality and spatial dependence of inter- and intra-provincial groups, and also the choropleth maps of clusters in China, this paper reaches the conclusion that clusters of prefectures and provinces with high positive spatial association are persistent over years in China, and the resulting highly correlated income disparity on both inter- and intra-provincial levels might be lasting for a relatively longer period, implying that spatial dependence is a contributing factor to the regional income inequality in a spatial context
