Es gibt weiterhin ökonomische Argumente für einen öffentlichen Rundfunk

Rafael AignerAnselm Mattes Ferdinand Pavel, Wirtschaftsdienst : Zeitschrift für Wirtschaftspolitik. - Heidelberg : Springer, ISSN 1613-978X, ZDB-ID 2079503-8. - Vol. 97.2017, 1, p. 45-52, January 2017

Recent economic literature criticises the size and mandate of public broadcasting in Germany. Technological progress has changed the methods of producing and distributing broadcasting content. Traditional broadcasting and print media have converged in a digital environment. Some of the classical arguments for publicly funded broadcasting have become invalid. This article argues that the converging media markets are nonetheless characterised by ongoing market failures, mostly because of positive external effects created by public value content. Markets will underprovide such content, which is why they should be publicly funded. We discuss the scope and form of public broadcasting and conclude that there are still economic reasons for dedicated public service broadcasters to exist.

The Fehmarn Belt Duopoly – Can the Ferry Compete with a Tunnel?

Rafael AignerKatharina Weber, Transportation Research Part A: Policy and Practice, 100, 1-15, May 2017

The Fehmarn Belt is a strait between Denmark and Germany, currently served by a ferry operator. We analyse competition between the ferry service and a planned tunnel, the Fehmarn Belt Fixed Link. We develop a differentiated duopoly model to address two questions: 1. Will the tunnel induce the ferry to exit the market once it operates? 2. Will the tunnel’s toll revenue suffice to cover its cost? Using real-world data and traffic forecasts, we show that it should not be taken for granted that the ferry will exit the market, and that if the ferry competes, the tunnel project will make a loss.
