Estimating network effects and compatibility in mobile telecommunications

Grajek, Michał - 2007

effects and compatibility between networks. Network effects are measured by the dependence of consumer willingness to pay on … the installed base of subscribers. Compatibility is measured by the relative extent of cross- and own-network effects. I … network effects and - despite full interconnection of the mobile telephone networks - low compatibility. I also show that …

Tariff-mediated network effects versus strategic discounting : evidence from German mobile telecommunications

Zucchini, Leon; Claussen, Jörg; Trüg, Moritz - 2013

Mobile telecommunication operators routinely charge subscribers lower prices for calls on their own network than for calls to other networks (on-net discounts). Studies on tariff-mediated network effects suggest this is due to large operators using on-net discounts to damage smaller rivals....

The nature and magnitude of the effects of asymmetric regulation of mobile termination rates on the Mexican retail prices

Robles-Rovalo, Arturo; Díaz-Goti, Emiliano; … - 2018

In theory, network profits are independent of the reciprocal termination rates when operators charge nondiscriminatory call prices (Laffont, Rey and Tirole, 1998). Additionally, termination rates can be used to subsidize subscriber acquisition cost. This issue is typically known as a "waterbed...

Benefits of regulation vs. competition where inequality is high : the case of mobile telephony in South Africa

Hawthorne, Ryan; Grzybowski, Lukasz - 2019

We test for the distributional effects of regulation and entry in the mobile telecommunications sector in a highly unequal country, South Africa. Using six waves of a consumer survey of over 134,000 individuals between 2009-2014, we estimate a discrete-choice model allowing for...

Evaluating market consolidation in mobile communications

Genakos, Christos; Valletti, Tommaso M.; Verboven, Frank - 2017

We study the dual relationship between market structure and prices and between market structure and investment in mobile telecommunications. Using a uniquely constructed panel of mobile operators’ prices and accounting information across 33 OECD countries between 2002 and 2014, we document...

Impact of competition and regulation on prices of mobile services : evidence from France

Grzybowski, Lukasz; Nicolle, Ambre; Zulehner, Christine - 2017

In this paper, we assess the impact of competition and regulation on prices of mobile services in France. We estimate hedonic price regressions using data on tariff plans offered by the main mobile telecommunications operator in France between May 2011 and December 2014. In this time period, the...

Does one more or one less mobile operator affect prices? : a comprehensive ex-post evaluation of entries and mergers in European mobile telecommunication markets

Csorba, Gergely; Pápai, Zoltán - 2015

This paper estimates the impact of entries and mergers on the price of mobile voice services in a panel database of 27 European Member States between 2003 and 2010. Our difference-in-differences econometric methodology exploits the variance in different structural changes between countries to...

A model of international roaming regulation and competition in European mobile markets

Baranes, Edmond; Cuong Hung Vuong - 2021

This paper investigates the impacts of the current roaming rules on domestic competition and welfare. We consider a model for two countries in which each country has two operators that compete in the retail market for access services and also in the wholesale market for roaming. We first derive...

The impact of RAN sharing

Ivaldi, Marc; Aimene, Louise; Jeanjean, Francois; … - 2021

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...

Impact of roaming regulation on revenues and prices of mobile operators in the EU

Grzybowski, Lukasz; Muñoz-Acevedo, Ángela - 2021

We empirically assess the impact of the EU roaming regulation on mobile operators' average revenues per user (ARPU) and retail prices. Using a differences-in-difference approach, hedonic price regressions and detailed operator and plan-level data we find that the regulation decreased mobile...
