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'...

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...

This paper studies the effects of a country’s regulatory setting and competitive environment on the performance of second-generation (2G) mobile telecommunication. We consider three dimensions of sector performance: entry time, service prices and diffusion. We address the question of...

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...

We document the evolution of product innovation and features in the mobile telephone handset market. We distinguish between two types of product innovation: vertical and horizontal innovation. Using data from 1990 - 2003, we find that some characteristics have subsequently become an industry...
