This paper investigates the incentives to invest in improving the quality (as distinguished to investment in a new activity) in telecommunication industry using the empirical example of wireless markets. We highlight that investment incentives are positively related to the potential for...

The relationship between technical progress and price competition is a controversial issue in economics. This paper highlights the fact that investment in technical progress is an authentic type of competition which benefits the consumers rather than the industry. This type of competition exists...

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

This paper shows that the correlation between the Net Promoter Score and consumers' Willingness To Pay in five European mobile markets is very strong. The Net Promoter Score is provided by a survey and the Willingness To Pay is calculated using the Spokes Model which is an economic model based...

We consider a horizontally and vertically differentiated duopoly model in order to analyse both intra- and inter-platform competition in a fully 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 impact of technical progress on the relationship between competition an investment. The competition is measured as the degree of substitutability and technical progress enlarges the size of innovation in cost reduction. In a context of duopoly, technical progress...

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....

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...

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...
