I examine the effects of FCC regulation on the innovation and introduction of advanced telecommunications services in the U.S. An interim of lighter regulation provides an experiment to test the regulatory regime''s impact on innovation. The econometric model comprises an arrival process (for...

This paper questions whether competition can replace sector-specific regulation of mobile telecommunications. We show that the monopolistic outcome prevails independently of market concentration when access prices are determined in bilateral negotiations. A light-handed regulatory policy can...

I generalize the workhorse model of network competition to include income effects in call demand. Empirical work has shown call demand to increase significantly with income. For any positive income effect, network operators prefer a termination rate above marginal cost if networks are...

This paper analyzes how competition works in mobile telecommuncations markets and, bases on this analysis, we discuss whether regulatory intervention in mobile telephone markets is justified from an economic perspective. Starting point of our analysis is the observation that an evaluation of...

In summer 2005, the German telecommunication incumbent Deutsche Telekom announced its plans to build a new broadband fibre optics network. Deutsche Telekom decided as precondition for this new network not to be regulated with respect to pricing and third party access. To develop a regulator's...

A mandatory open-network-provision (ONP) by dominant firms is the appropriate government regulation in the presence of network externalities. For basic telephone services and online services, a permanent ONP regulation seems indispensable, whereas telecommunication networks only require...

This paper endogenizes the interplay between innovation by a regulated firm and regulatory delay. When product innovation costs fall over time, an extra day of regulatory delay increases time to introduction by more than a day. In the signaling model, the firm therefore times its innovation to...

Die Alternative 'Ex-Ante-Regulierung versus Ex-Post-Aufsicht' ist der Kern der ordnungspolitischen Kontroversen der letzten Jahre im Bereich der Netzindustrien - insbesondere in der Telekommunikation und der Energiewirtschaft. Die grundlegenden Reformen des ordnungspolitischen Rahmens haben in...

This study analyzes the progress in information and communication technologies (ICT) in eleven MED countries and how they compare to the rest of the world in terms of sector's sophistication and development. In recent years, most countries of this region opened up their markets for multiple...
