Most existing empirical work on technology diffusion assumes technologies to remain constant throughout the diffusion process. However, many consumer technologies improve significantly over time. Using data on the characteristics of new mobile handsets over a ten-year period and controlling for...

This paper studies five mergers in the European wireless telecommunication industry and analyzes their impact on prices and capital expenditures of both merging carriers and their rivals. We find substantial heterogeneity in the relationship between increases in concentration and carriers'...

We estimate the effect of broadband infrastructure, which enables high-speed internet, on economic growth in the panel of OECD countries in 1996-2007. Our instrumental-variable model derives its non-linear first stage from a logistic diffusion model where pre-existing voice-telephony and...

Recent and ongoing investments into telecommunications infrastructure have facilitated the repeated waves of digitization, both in personal and professional life. I address the question of which actors should contribute to investment costs into telecoms infrastructure and how. One widely...

Moderne Kommunikationsnetze tragen zur Verbreitung von Wissen und Information bei und sind daher für die wirtschaftliche Entwicklung von Industrienationen wie Deutschland von zentraler Bedeutung. Insbesondere stellt der Umbau der Netzarchitektur vom traditionellen vermittelten Sprachtelefonnetz...

Nach den Ergebnissen einer neuen Studie des ifo Instituts hat der Ausbau von Breitbandnetzen positive Effekte auf das Wirtschaftswachstum. Die Analyse der jährlichen Daten von 25 OECD-Ländern über den Zeitraum 1996 bis 2007 zeigte, dass nach der Einführung von Breitbandinfrastruktur in einem...
