Lars-Hendrik Röller, European School of Management and Technology, Berlin, diskutiert, wie sich die Regulierung im Telekommunikationssektor auf Investitionen in die IKT-Infrastruktur von Netzeignern und Wettbewerbern auswirkt. Neue Forschungsergebnisse deuten darauf hin, dass die Intensität...

The roam-like-at-home regulation (RLAH) eliminated all mobile roaming surcharges to Eu-ropean consumers travelling within the European Economic Area (EEA). We measure the causal impact of the regulation on EEA roaming traffic, using the Rest of the World as a control group. We find large and...

The aim of our paper is to determine the efficiency of asymmetric regulation of mobile termination rates (MTRs) in a market where firms are differentiated in size and with commercial offers including calling club effects. Major regulatory issues are related to these analyses, since some European...

We provide evidence of an inherent trade-off between access regulation and investment incentives in telecommunications by using a comprehensive data set covering 70 fixed-line operators in 20 countries over 10 years. Our econometric model accommodates: different investment incentives for...

In this paper we analyze the risks the European Telecom market is experiencing. Many economic disincentives to investing in infrastructure are related to the fact that market value of the companies can be lower than expected. Next Generation Networks (NGN) deployment require great amounts of...

This article addresses the impact of regulatory policy on levels of infrastructure deployment and derived welfare in the telecommunications sector. The model considers two potentially coexisting and partially competing techniques (the "old" ADSL - Asymmetric Digital Subscriber Line - technique)...

The distinguishing feature of two-sided markets is that the pricing structure, that is, the relative prices charged to each side, matters. Regulators need to understand and account for the interdependence of prices in both sides. Some interventions that lower the prices on one side can result in...

This paper examines the impact of regulatory intervention to cut termination rates of calls from fixed lines to mobile phones. Under quite general conditions of competition, theory suggests that lower termination charges will result in higher prices for mobile subscribers, a phenomenon known as...

We evaluate the welfare effects of the Roam-Like-At-Home regulation, which drastically re-duced the price of accessing the mobile internet for EU residents when traveling abroad in the European Economic Area. Estimates from individual-level usage data suggest that consumer surplus increased by...

The Federal Communications Commission is coming under intense political pressure to reclassify broadband Internet access as a common carrier telecommunications service under Title II of the Communications Act. Yet, almost no attention has been directed at the fine details of how reclassification...
