We use panel data on 36,104 municipalities in metropolitan France over the period 2010-2014 to estimate two models of entry into local markets by: (i) alternative operators using wholesale access to the legacy copper network via local loop unbundling (LLU), and (ii) the incumbent and two...

We investigate the effect of competition on quality in regulated markets (e.g., health care, higher education, public utilities), using a Hotelling framework, in the presence of sluggish demand. We take a differential-game approach, and derive the open-loop solution (providers choose the optimal...

In a spatial competition setting there is usually a non-negative relationship between competition and quality. In this paper we offer a novel mechanism whereby competition leads to lower quality. This mechanism relies on two key assumptions, namely that the providers are motivated and...

This paper analyzes two business practices on the mobile internet market, paid prioritization and zero-rating. Both violate the principle of net neutrality by allowing the internet service provider to discriminate different content types. In recent years these practices have attracted...

We analyze the demand and supply characteristics of the Indian telecommunications market, in order to assess the potential effectiveness of universal access policies in developing countries. We provide some empirical evidence on the supply and demand characteristics, using a small...
