We propose a novel approach to the evaluation of new network technologies that combines an engineering cost model with a differentiated multi-player oligopoly model subject to wholesale access regulation. It is based on Hoernig et al. (2010), 1 which examines the cost differentials and...

In this paper we consider and evaluate NGA architectures which meet the foreseeable future bandwidth demand and allow for highest bandwidth and quality for end-users and which no longer rely on copper cable elements. These are FTTH architectures only. From all available FTTH architectures we...

Two-part tariffs, when used at the retail level, increase efficiency by lowering the price of marginal units. The same potential for higher efficiency exists for two-part tariffs at wholesale level for a given market structure, but the fixed part of the wholesale tariff can negatively affect the...

In this paper, we study the impact of co-investment by incumbents and entrants on the roll-out of network infrastructures under demand uncertainty. We show that if entrants can wait to coinvest until demand is realized, the incumbents' investment incentives are reduced and total coverage can be...

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...
