In this paper, we design a theoretical model to analyze the impact of the number of firms on investment in the wireless communications industry. Our model extends the Salop's framework by introducing investment in quality that either reduces the marginal cost of production or shifts the...

The optimal market structure in the mobile industry is an important topic in the mobile industry. In this paper, we use two theoretical frameworks and a structural estimation approach to assess the effects of market structure on consumer surplus in symmetric mobile markets. When mobile services...

According to static models of industrial organization, a rise in competition decreases prices. In this paper, I test whether this conclusion can be reversed in the mobile telecommunications markets where dynamic efficiency effects might be significant. The empirical test relies on the change in...

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...

We develop a model of competition in prices and infrastructure among mobile network operators. Consolidation can increase market power, but economies of scale, which we derive from physical principles, lead to more efficient data transmission. Estimating our model with French consumer and...

Dynamic models of industrial organization predict that more competition would increase price if the magnitude of the dynamic efficiencies outweighed the static one. In this paper, I test whether this prediction holds in the wireless markets where the dynamic efficiencies might be significant....

Telecommunications industry requires a high and steady level of investments in successive generations of equipments to cope with the exponential growth of traffic volumes. This paper argues that in this context, only imperfections of competition provide market players with the necessary margins...

This article studies the impact of the sharing of traffic costs between an Internet access provider and a content provider, both of which have a monopoly on their market. It shows that when the content provider charges consumers for content, cost sharing triggers a virtuous circle that...

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 studies the effects of infrastructure sharing agreements on telecommunications markets. Using an oligopoly model with an investment stage where firms compete " à la Cournot", I find that provided no firm is excluded, infrastructure sharing agreements decrease prices, increase...
