This paper investigates the high-speed broadband situation in the EU and its prospects. It uses a deployment model to estimate the investment required to meet the Digital Agenda for Europe (DAE) broadband targets set by the European Commission in its Europe 2020 strategy at different stages: as of 2016, after expected operators’ deployment, after public subsidies and leveraged investment, and as expected in 2020. The model uses data at the NUTS3 level, which is the most granular level that has data available on the status of broadband deployment, to arrive at a coherent and comparable framework. From the different perspectives on the investment to meet DAE targets, the paper concludes on the need for an appropriate combination of incumbent and alternative operators investments, public subsidies and leveraged investments, and new investments, both public and private and non-existing as of 2016, examining their feasibility and the impact of different regulatory, technical, and policy strategies. 相似文献

This paper examines the diffusion process of Internet broadband access in Japan by modeling the household choice of access modes. Estimates reveal that the characteristics of users, rather than those of the access modes, play a significant role in demand substitution across the modes. Simulation exercises indicate that had optic fibers (fiber-to-the-home; FTTH) been made available to the whole country in 2005, only 10% of households would have switched to that mode. This result implies that once chosen, the household choice of access mode persists, and that indirect network effects are an important element in decisions to adopt the new technology of broadband. Finally, policy implications are discussed. 相似文献

In many countries worldwide access networks are in the transition from copper to fiber access. During the transition phase copper and fiber networks are operated in parallel. All regulators facing this situation of technological change have to decide how to price unbundled access to the copper loop in this transition phase. Should they keep the usual forward looking long-run incremental cost standard charge, or should they move to some different approach? The authors propose to price copper access based on the modern equivalent asset (MEA) of fiber access. Since fiber access is superior to copper access, the cost of fiber access (as a basis for pricing copper access) should, however, be corrected by the performance delta between copper and fiber access. 相似文献

Using a novel approach to the evaluation of new network technologies that combines an engineering cost model with a differentiated multi-player oligopoly model with wholesale access regulation this article evaluates the choice among different Fibre-to-the-Home (FTTH) architectures. The cost modelling relies upon an engineering bottom-up approach that feeds into a competition model. For addressing competition the pyramid model was chosen, which is an extension of the Hotelling model to multiple firms/services. The paper solves for price setting Nash equilibria between an incumbent, wholesale-access-based entrants and cable as an additional fully integrated network competitor. Welfare tradeoffs are highlighted with respect to cost differences and QoS differences between the various FTTH architectures and between the modes of regulation. According to the analysis architectures that can be unbundled (and that allow for greater speeds) outperform, from a social welfare perspective, architectures that (realistically) allow only for bitstream access. 相似文献

Due to the high costs associated with the deployment of the passive infrastructure of FTTH networks, a few alternative operators have pondered the possibility of making co-investments based on a network sharing model. The purpose of this article is to explore economic aspects of a co-investment scheme for present and future FTTH/PON architectures. The article describes the cost reductions that can be achieved when a co-investment scheme is used, as well as the relationship between market shares and the cost per home connected. A cost model was employed to calculate the investment per home passed and the investment per home connected. The investment per home passed for an alternative operator indicates significant cost reductions when a co-investment scheme is used. On the other hand, the results show that when the incumbent's market share is equal or higher than the total market share of all the alternative operators that share the network infrastructure, the investment per home connected for an alternative operator is higher than that for the incumbent operator. Moreover, to be cost competitive with the incumbent operator, the necessary market share that each alternative operator should achieve is much lower than that of the incumbent operator. 相似文献
