This paper studies the effect of termination rates on substitution between fixed and mobile calls and access, in a model where heterogeneous consumers can subscribe to one or both types of offers. Simulations show that each (fixed or mobile) termination rate has a positive effect on the take-up...

We show that the prediction of strategic connectivity breakdowns under a receiving-party-pays system and discrimination between on and off-net prices does not hold up once more than two mobile networks are considered. Indeed, if there are at least three competing networks and enough utility is...

We show that the waterbed effect, i.e. the pass-through of a change in one price of a firm to its other prices, is much stronger if the latter include subscription rather than only usage fees. In particular, in mobile network competition with a fixed number of customers, the waterbed effect is...

Often, fixed-line incumbents also own the largest mobile network. We consider the effect of this joint ownership on market outcomes. Our model predicts that while fixed-to-mobile call prices to the integrated mobile network are more efficient than under separation, those to rival mobile networks...

We present a calibrated model of the UK mobile telephony market with four mobile networks; calls to and from the fixed network; network-based price discrimination; and call externalities. Our results show that reducing mobile termination rates broadly in line with the recent European Commission...

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...

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...
