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...

This paper investigates the impact of technical progress on the relationship between competition an investment. Using a model of oligopoly competition with di¤erentiated products where firms invest to reduce their marginal cost of production, I find that technical progress, which increases the...

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...

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...

This paper analyzes how market power can be measured in an industry characterized by significant technological progress. Using a Cournot’s oligopolistic framework with exogenous innovation and costly investment in new technology, It shows that the Lerner index and the Herfindahl-Hirschman...

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...
