In this paper, we address the issue of the appropriate market structure in European mobile markets by presenting empirical evidence on the effect of the number of MNO on investment. Using a structural entry model based on a country-level dataset of 28 European countries, we find that, in average...

Using source WCIS (World Cellular Information Service) for the tangible investments of mobile operators and mobile spectrum licenses, we are able to build a database matching the level of investment per capita with average license duration for 14 countries (representing more than 75% of the...

Mobile industry is characterized by a sharp fall in megabyte price which highly benefi ts to consumers. This article aims to identify the main parameters that lead to such a fall and shows that the growth of traffic is by far the main cause. It proposes a parametric model that explains the...

This paper proposes a mathematical competition model for mobile operators based on a price competitive equilibrium with horizontally differentiated offers "à la Hoteling" and quality variations between companies. The model’s parameters can be specified from observable data. The proximity...

This paper investigates the relationship between technical progress, competition, and the impact on consumer's surplus and welfare. A Hotelling model in symmetrical duopoly with full market coverage is introduced. Firms invest in order to improve the quality of their offer and thus consumers'...

A recent study recommends to reinforce copper access regulation in order to promote NGA take-up and penetration. In particular it proposes to strengthen the unbundling obligations and to lower ULL price. However, these recommendations are not consistent with figures from the report itself....

We consider a horizontally and vertically differentiated duopoly model in order to analyze both intra- and inter-platform competition in an always covered broadband access market (Copper-Copper, Copper-FTTH and FTTH-FTTH competitions). The model is purely static and does not address dynamic...

This paper investigates the incentives to invest in improving the quality of service (as distinguished to investment in a new activity) in telecommunication industry. This kind of investment is very important in telecommunication industry because of the rapid technological progress that makes...

This paper investigates the impact of the copper access regulation on broadband adoption in each technology (xDSL on copper infrastructure, FTTx on fiber infrastructure and cable modem). We modelize adoption with a logistic function. Using a 15 European countries dataset we find a negative...

The local authorities, in particular via Delegations of Public Utility (DPU), develop telecommunications infrastructures which often duplicate infrastructures of the incumbent operator. Such infrastructures are financed partly by public subsidies which must allow competition to develop, even in...
