"Im folgenden wird der Versuch gemacht - auf der Basis der Angaben von 1969 Betrieben des verarbeitenden Gewerbes aus dem Jahre 1976 - Arbeitsplätze nach Qualifikationsanforderungen und nach Attraktivität der Arbeitsbedingungen zu strukturieren und zu ermitteln, wo ausländische Arbeitnehmer...

Our market modelling approach aims at practically determining wholesale pricing policies for the switch from copper to fibre access networks. It asks which market equilibria for incumbents and entrants result from different combinations of copper and fibre wholesale access charges. We first...

It is common knowledge that Next Generation Access (NGA) networks require significant investments and that for many regions, especially in more rural areas, there is no viable business case. In this paper a bottom-up cost modelling approach is applied to determine the investment and cost of...

This article examines three major changes which have been occuring in the telecommunications market: liberalization, leading to increased competition in services and equipment, the internationalization of the equipment market, and a rapidly changing industrial structure. The interrelationship...

This article discusses the problems which arise if liberalization in telecommunications has to be brought about under strong equity constraints. It is shown that, under West Germany's political framework, the average consumer exerts a much larger influence on telecommunications policy than in,...

VDSL and G.fast Vectoring are transmission technologies over copper access line pairs enabling the transmission of higher bandwidth to the end customers, but harm the infrastructure based competition using physical unbundled copper lines. Thus regulators have to decide between infrastructure...

There is an ongoing discussion in the market which Next Generation Access (NGA) architecture best suits future needs and which investment and cost differences exist. The discussion can be subsumed as P2P vs. GPON, which is somewhat misleading as this article reveals. The discussion is driven by...

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...
