In many countries worldwide access networks are in the transition from copper to fiber access. During the transition phase copper and fiber networks are operated in parallel. All regulators facing this situation of technological change have to decide how to price unbundled access to the copper...

With the use of a laboratory experiment, we show the effects of co-investments on coverage, competition and price collusion in regulated network industries. On the one hand, co-investments turn out not to be a significant driver of new infrastructure investments beyond the level achieved by...

International mobile roaming cartel agreements prompted the EU to intervene, firstly encompassing competition law measures by a cartel exemption, then initiating several competition proceedings based on the accusation of abuse of a dominant market position, and finally applying price regulations...

The changing role of the Internet Engineering Task Force (IETF) standard setting process from designing and implementing the best effort TCP/IP protocol as a universal standard towards a platform for dealing with the increasing need for variety in the design of a Quality of Service (QoS)...

In order to create incentives for Internet traffic providers not to discriminate with respect to certain applications on the basis of network capacity requirements, the concept of market driven network neutrality is introduced. Its basic characteristics are that all applications are bearing the...

In the U.S. paying for priority arrangements between Internet access service providers and Internet application providers to favor some traffic over other traffic is considered unreasonable discrimination. In Europe the focus is on minimum traffic quality requirements. It can be shown that...

Disruption of tradition network industries and the emergence of innovative physical operator platforms provide challenging governance problems of contractual relationships among different actors involved. The problem solution competence of operator platforms (two-sided, multi-sided) is the...

The transition towards 5G-based smart network industries is concomitant with a fundamental change of the traditional physical infrastructures driven by digitalization which pervades all decision-relevant components of the infrastructure value chains. The goal of this paper is to develop a...

In this paper the potentials for shared mobility services based on ICT innovations are charac-terized, requiring a paradigm shift from intramodal transportation markets to intermodal shared mobility markets. Heterogeneous ICT innovations are described, entailing various combinations of app-based...
