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...

The common aim of legislation in the field of competition and consumer protection is to ensure the consumers’ sovereignty and well-being. Based on the analysis of literature in this field we have established, as the main focus of our research, a study of the correlation between the degree of...

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...

We explore the existence of first mover advantages in mobile telecommunications markets. Building on a data set comprising monthly penetration rates, market concentration, number of active operators, and market shares of 90 followers from 33 OECD countries, we estimate a dynamic growth model....

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...

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...

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...

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...

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...

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...
