This paper investigates the effects of access to high-speed internet on innovation and entrepreneurship in Africa. The identification strategy exploits the staggered arrival of submarine internet cables to the coast of Africa and the subsequent rollout of terrestrial fiber network across the...

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...

We evaluate the impact of mobile operators merger on unitary price of data and voice by using country-level observations on data retail revenue, cellular data traffic, voice retail revenue, outgoing voice minutes. Using difference-in-differences estimation strategy, we estimate the effect of...

This paper addresses the empirical relationship between the level of competition and the rate of productivity growth across thirty sectors of the French production system during the period 1978- 2015. It shows that there exists an optimal level of competition for each sector that is defined by...

Using source WCIS (World Cellular Information Service) for the tangible investments of mobile operators and mobile spectrum licenses, we are able to build a database matching the level of investment per capita with average license duration for 14 countries (representing more than 75% of the...

In this paper, we formulate and estimate a structural model of demand to analyse the equilibrium effect of the RAN sharing by using cross-country panel data in 28 EU countries in years 2010-2020. Based on model estimates, our simulation analysis in Spain firstly provides a quantitative...

This paper studies the effects of infrastructure sharing agreements on telecommunications markets. Using a model with an investment stage where firms compete" 'a la Cournot", I find that, infrastructure sharing agreements increase investment at industry level. Indeed, the sharing of...
