Developments in the EU telecommunications markets require a recurrent redesign of the regulatory framework for telecommunications services. In this regard, the analysis of the substitution effects between different types of telephony is the cornerstone of market definition and therefore of...

Der Weg in die Gigabitgesellschaft: Wie sollen Breitbandziele in Deutschland über das Jahr 2018 hinaus konkret definiert, umgesetzt und finanziert werden? Dorothee Bär, Bundesministerium für Verkehr und digitale Infrastruktur, weist darauf hin, dass das BMVI gleich zu Beginn der aktuellen...

Eine moderne Telekommunikationsinfrastruktur ist für die wirtschaftliche Entwicklung eines Staates von außerordentlich großer Bedeutung. Czernich et al. (2011) zeigen im Rahmen einer internationalen Studie, dass ein Anstieg in der Breitbandpenetration von 10 Prozent zu einer Steigerung des...

This paper develops the hypothesis that the inclusion of multiple objectives into laws widens the discretionary powers of executive institutions. As the decision how to balance trade-offs is removed from the political to the executive sphere, policy making becomes less transparent and also less...

This paper provides an empirical analysis how tariff diversity affects fixed-line broadband uptake, utilizing a new data set with 1497 fixed-line and 2158 mobile broadband tariffs from 91 countries across the globe. An instrumental variable approach is applied to estimate demand, controlling for...

This paper deals with the relationship between the traditional fixed-line, mobile and Voice over IP telephony in the EU.We estimate the supply and demand for fixed-line telephony using data on 25 EU member states for the 2006:Q2 - 2011:Q4 period. Employing instrumental variable approach, we...

This paper analyzes the relationship between the traditional fixed-line, mobile and Voice over IP (VoIP) telephony in the EU. In doing so, it aims at filling the gap in the empirical literature on the substitution patterns between these technologies in a comprehensive way. It relies on demand...

This paper provides an empirical analysis how tariff diversity aspects fixed-line broad-band uptake, utilizing a new data set with 1497 fixed-line and 2158 mobile broad-band tariffs from 91 countries across the globe. An instrumental variable approach is applied to estimate demand, controlling...

We conduct a laboratory experiment that tests two fundamental predictions unique to salience theory. If an agent purchases one of two vertically differentiated products, salience theory makes the following two distinct predictions. First, it hypothesizes that a higher expected price level for...
