Public policy in the digital age : evidence from telecommunications and digital platforms

Abstract : This doctoral thesis studies questions relevant for public policies in the context of the digital transformation of the world economy. It examines new situations and public interventions on the telecommunications and digital sectors affecting people’s mobility and their integration in the digital economy. It is divided into three chapters.The first chapter assesses the impact of the roaming regulation implemented in the European Union on mobile operators’ revenues and retail prices. The results suggest that the regulation decreased mobile operator’s revenues per user, while having no impact on prices during the latest phase of the regulation. Thus, we find no evidence of a strategic reaction to the regulation by mobile operators.The second chapter studies the determinants of fiber entry by telecommunications’ operators and evaluates the efficiency and the impact of a State aid plan for the deployment of ultra-fast broadband networks in France. On the determinants of fiber entry, we identify market size and income as important characteristics that increase the attractiveness of local markets. Moreover, we find evidence of a strong geographic dependence in the fiber entry process, the presence of a replacement effect from the legacy copper network and an increase in the ease of entry over time. On the evaluation of the plan, we find that it was overall efficient and helped increase fiber coverage in aided municipalities at the early stages of fiber diffusion.The third chapter studies challenges of transport policy in the presence of ride-hailing platforms. Specifically, it assesses the impact of these platforms on the incidence of drunk-driving fatal crashes and fatalities, using Chile as a case study. Moreover, it studies heterogeneous effects in fatalities by gender. The results suggest that, ride-hailing platforms significantly reduced drunk-driving fatal crashes and fatalities in Santiago. In particular, it helped decrease the number of female passengers’ fatalities and the number of male drivers’ fatalities at night.
