In this paper we study how the coexistence of access regulations for legacy (copper) and fiber networks shapes the incentives to invest in network infrastructure. To this end, we develop a theoretical model explaining investment incentives by incumbent telecom operators and heterogeneous...

This paper looks at the effects of different forms of wholesale and retail regulation on retail competition in fixed network telephony markets. We explicitly model two asymmetries between the incumbent operator and the entrant: (i) While the incumbent has zero marginal costs, the entrant has the...

In September 2016, the European Commission (EC) published its proposal for a directive establishing the European Electronic Communications Code (EECC) - with one key aim being the provision of sufficient incentives for infrastructure investments into high-speed communication networks. Based on a...

This paper examines mobile termination fees and their regulation when networks are asymmetric in size. It is demonstrated that with consumer ignorance about the exact termination rates (a) a mobile network's termination rate is the higher the smaller the network's size (as measured through its...

We empirically assess the impact of the EU roaming regulation on mobile operators' average revenues per user (ARPU) and retail prices. Using a differences-in-difference approach, hedonic price regressions and detailed operator and plan-level data we find that the regulation decreased mobile...

This paper gives a survey of the current state of competition in the German Broadband access market. Existing regulations and their impact on the deployment of high-speed Internet access are evaluated. It is argued that facilities-based competition is preferable to open-network regulations. The...
