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...

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...

This paper investigates the relationship between competition and investment in the wireless industry from a dynamic perspective. Using firm level data and instrumental variable estimation strategy, it finds that the relationship is inverted-U shaped, with an investment maximising intensity of...

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 empirically assesses the impact of the intensity of competition on investment in new technologies within the mobile telecommunications industry. Using firm level panel data and an instrumental variable estimation it finds an inverted-U relationship between competition intensity and...

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...

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...
