Die Debatte um den Ausbau von Mobilfunk- und Glasfasernetzen in Deutschland bedarf einer Objektivierung. Statt Ängste zu schüren, gilt es nüchtern zu überprüfen, ob die Privatisierung der physischen Infrastruktur vor rund 25 Jahren sowie die getrennte Betrachtung von Glasfaser- und...

This paper provides evidence that superior mobile Internet infrastructure increases take-up of location-based online services. Using data from the largest German online platform for restaurant reviews, I find that upgrading the 2G network to 3G increases the number of restaurant reviews and the...

This study presents a comprehensive analysis of the tax burden on the mobile telecommunications sector across twenty-nine African countries, encompassing both general taxation and sector-specific levies. To conduct this assessment, we develop a model of a representative mobile network operator,...

Internet of Things (IoT) technologies are of particular interest for telecommunication companies that can significantly affect the interaction of economic agents. As a result of the growth in the number of connected devices, the introduction of cloud services and business applications it became...

Fixed to mobile substitution is a trend that is reshaping the telecommunications industry. Telkom's response to this trend, for example, has been to build a mobile network to recapture revenues lost to mobile operators. The question is, to what extent are fixed and mobile networks substitutes,...

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 contribute to the role of telecommunications infrastructure on economic growth in three ways. We separately examine fixed-line and mobile telephone subscription levels. We compare an early build out period to a later more mature industry phase. And we develop a method designed to address...

Network shares and retail prices are not symmetric in the telecommunications market with multiple bottlenecks which give rise to new questions of access fee regulation. In this paper we consider a model with two types of asymmetry arising from different entry timing, i.e. a larger reputation for...
