In this paper we carry out technical efficiency and productivity growth comparisons among the four largest European carriers and eight of their American counterparts. The time period of our comparisons is 1976 through 1986. This is a particularly interesting period since it begins just after the...

This paper tests whether upstream R&D cooperation leads to downstream collusion. We show that a sufficient condition for identifying collusive behavior is a decline in the market share of firms participating in research joint ventures (RJVs). Using information from the U.S. National Cooperation...

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

Using data on prices, production, and exports, we are able to identify marginal costs as well as the effectiveness of the Norwegian cement industry cartel. We find that our marginal cost estimates are very much in line with the detailed cost accounting data. We show that the cement cartel has...

This paper considers merger control in a common agency framework where firms and their competitors can influence the antitrust agency and where transparency while making lobbying less effective also implies real resource costs. We examine the performance of two alternative standards that can be...

In this paper we specify and estimate a structural model which links product market competition and union power. The model has a two-stage setting in which wages are determined through bargaining between management and unions in the first stage, with a price-setting market game to follow in the...

Over the last decade, sector-specific regulation has been used to promote competition in European network industries. Given that competition is still rudimentary in some sectors, this process is still not finished. As a result, Member States have continued to remove regulatory barriers in...

In der abschließenden Podiumsdiskussion, die sich noch einmal mit dem Themenbereich IKT-Infrastruktur befasst, diskutieren Roland Berger, René Obermann, Lars-Hendrik Röller, Hans-Werner Sinn und Roland Tichy, „wie wir Investitionen in moderne Breitbandnetze bekommen“. Dabei ging es vor...

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...
