On 23-24 September 2013 in Geneva, Switzerland, the International Telecommunication Union (ITU) hosted a high-level workshop on international mobile roaming, which was convened to discuss the regulatory and industry initiatives that have sought to improve competitive outcomes for international...

The FCC’s net neutrality rules sought to limit interference by broadband service providers in markets for Internet-based content and applications. But to do so, the Commission significantly reduced the amount of innovation possible in the broadband service market. Within limits, broadband...

Mobile telephony is described as a two-sided market where customers are seen as senders and receivers of communications that are mutually beneficial both to callers and receivers. This has implications in terms of market definition and market power. The economics of mobile call termination is...

This paper provides a structural interpretation to the estimates of the shape and position of nonlinear tariffs. We focus on the evaluation of price-cost margins, and thus we need to identify marginal cost from an equilibrium model of nonlinear pricing competition. We estimate these price-cost...

The European Union adopted a Roaming Regulation (717/2007) in 2007, then extended its duration and widened its scope (544/2009) in 2009. In 2006, the European Commission held two consultations on a possible regulation. It made a formal legislative proposal in July 2006, to implement wholesale...

This paper examines the influence of mobile network competition on the prices of fixed-to-mobile calls. Because fixed line customers cannot, in general, distinguish the identity of a specific mobile network, these networks have market power when setting termination charges for calls from fixed...

This paper surveys the recent literature on competition between mobile network operators in the presence of call externalities and network effects. It shows that the regulation of mobile termination rates based on "long-run incremental costs" increases networks' strategic incentives to...

International mobile roaming has been subject to market interventions since the 1990s, first requiring operators to be provide customers with roaming, then trying to limit the increasing prices, that were seemingly immune to the effects of competition. The European Commission, in trying to...

The persistence of high prices for international mobile roaming has been part of the global regulatory agenda for half a decade. In Africa, there have been studies but, as yet, no regulatory action. Yet, the initiative of one large operator has seen the introduction of trans-national tariffs...
