Unbundling the incumbent and deployment of high-speed internet: Evidence from France

In this paper, we study the impact of competition on the legacy copper network on the deployment of high-speed broadband. We first develop a theoretical model, which shows that the relation between the number of competitors and investment in a quality-improving technology can be positive if the quality of the new technology is high enough, and is negative otherwise. We test these theoretical predictions using data on broadband deployments in...
