Our survey reviews the theoretical and empirical literature on all alternative policies to promote the deployment of new fiber-based communications infrastructure. Since such investment is expected to induce substantial positive externalities, dynamic efficiency becomes a particularly important...

This paper examines the determinants of sector-specific regulation imposed on broadband markets related both to efficiency objectives of regulators and to those of narrowly defined interest groups. We test hypotheses derived from the normative and positive theoretical literature employing recent...

The economics literature on Net Neutrality (NN) has been largely critical of NN regulation on the basis of theoretical findings that NN violations can be both welfare improving and welfare deteriorating, depending on the circumstances of the case in question. Thus, an ex post competition policy...

Our survey reviews the theoretical and empirical literature on all alternative policies to promote the deployment of new fiber-based communications infrastructure. Since such investment is expected to induce substantial positive externalities, dynamic efficiency becomes a particularly important...

Contractual and regulatory provisions for access affect incentives to invest in an upgraded network and, in particular, a next-generation access network. Investment decisions are made under uncertainty and have to be made over time. This papers provides a framework for taking uncertainty, risk...

We characterize a monopolist's optimal offer of service plans when only informed customers know already at the contracting stage whether their demand is high or low, while uninformed customers may learn their demand only after incurring some costs, if at all. While informed customers purchase...

Wir untersuchen die Rolle von Vertragstypen und Zugangsregulierung auf Innovation und Wettbewerb. In einem Duopolmodell zeigen wir, dass Ex-post-Verträge, die nach den Investitionsentscheidungen getroffen werden, zu einer Welt führen, in der seltener Infrastruktur dupliziert wird, in der es...

Central features of today's electronic communications markets are complementarities between the different layers of the value chain, substitutability between some applications, network effects in the provision of content and services, two-sided business models that partly involve indirect...

Der vorliegende Beitrag gibt einen Überblick über die wesentlichen ökonomischen Aspekte der so genannten Sharing-Economy. Bei den dort tätigen Unternehmen handelt es sich zumeist um Plattformen, die direkte Transaktionen zwischen Akteuren mit dem Zweck einer temporären Nutzung dauerhafter...

Die Autoren untersuchen die Funktionsweise von Datenmärkten. Besonderes Augenmerk wird dabei auch auf Substitute zu einem "Handel mit Daten" im engeren Sinne gelegt. Die Unterscheidung zwischen personenbezogenen und nicht personenbezogenen Daten ist für die Analyse der Funktionsweise und...
