At the same time prices decline steadily with the latest trend being that operators offer voice services free of charge, the costs of which are covered by a monthly subscription charge. Against this background the paper examines the state of policy and regulatory reform in the telecommunications sector in Germany almost 10 years after the liberalisation of the fixed telecommunications market. Thereby the focus is on the analysis of the competitive conditions that have been established on the German market for voice telephony services. If these retail markets are competitive, there might be a need to remove remaining regulatory provisions. In the new environment of converging markets the future challenge of regulating fixed telecom markets might be to ensure that access to the network and/or services of a potentially dominant provider in a relevant market will satisfy requirements for openness and non-discrimination.}, subject = {Telekommunikationsmarkt}, language = {en} } @inproceedings{FredebeulKrein2007, author = {Fredebeul-Krein, Markus}, title = {10 Jahre Wettbewerb auf dem deutschen Telekommunikationsmarkt: Zeit f{\"u}r einen Paradigmenwechsel in der Regulierung?}, year = {2007}, abstract = {1.

The objective is to create modern telecommunications networks based on powerful broadband infrastructures". In doing so, they aim for innovative and investment-friendly concepts. For instance, in a recently published consultation paper on the subject the German regulator BNetzA declared that it will take "greater account of … reducing risks, securing the investment and innovation power, providing planning certainty and transparency - in order to support and advance broadband rollout in Germany". It further states that when regulating wholesale rates it has to be ensured that "… adequate incentives for network rollout are provided on the one hand, while sustainable and fair competition is ensured on the other". Also an EC draft recommendation on regulated network access is about to set new standards for the regulation of next generation access networks. According to the recommendation the prices of new assets shall be based on costs plus a projectspecific risk premium to be included in the costs of capital for the investment risk incurred by the operator. This approach has been criticised from various sides. In particular it has been questioned whether such an approach is adequate to meet the objectives of encouraging both competition and investment into next generation access networks. Against this background, the concept of "long term risk sharing contracts" has been proposed recently as an approach which does not only incorporate the various additional risks involved in the deployment of NGA infrastructure, but has several other advantages. This paper will demonstrate that the concept allows for competition to evolve at both the retail and wholesale level on fair, objective, non-discriminatory and transparent terms and conditions. Moreover, it ensures the highest possible investment incentive in line with socially desirable outcome. The paper is organised as follows: The next section will briefly outline the importance of encouraging competition and investment in an NGA-environment. The third section will specify the design of long term risk sharing contracts in view of achieving these objectives. The fourth section will examine potential problems associated with the concept. In doing so a way of how to deal with them will be elaborated. The last section will look at arguments against long term risk sharing contracts. It will be shown that these arguments are not strong enough to build a case against introducing such contracts.}, subject = {Electronic Commerce}, language = {en} } @inproceedings{FredebeulKrein2016, author = {Fredebeul-Krein, Markus}, title = {Towards trade facilitation via regulatory convergence: An analysis of the TTIP chapter on Electronic Communications}, series = {Regional ITS Conference of the International Telecommunications Society.

Cambridge, United Kingdom, 7-9 September 2016}, pages = {29 Seiten}, year = {2016}, abstract = {To give the exchange of goods and services between the European Union (EU) and the United States (U.S.) new momentum the two parties are currently negotiating the transatlantic free trade agreement Transatlantic Trade and Investment Partnership (TTIP). The aim is to create the largest free trade area in the world. The agreement, once entered into force, will oblige EU countries and the U.S. to further liberalize their markets. The negotiations on TTIP include a chapter on Electronic Communications/ Telecommunications. The challenge therein will be securing commitments for market access to Electronic Communications services. At the same time, these commitments must reflect the legitimate need for consumer protection issues. The need to reduce Electronic Communications-related non-tariff barriers to trade between the Parties is due to the fact that these markets are heavily regulated. Without transnational rules as to regulations national governments can abuse these regulations to deter the market entry by new (foreign) suppliers. Thus the free trade agreement TTIP affects in many respects regulatory provisions on and access to Electronic Communications markets. The objective of this paper is therefore to examine to what extend the regulatory principles for Electronic Communications markets envisaged under TTIP will result in trade facilitation and regulatory convergence between the EU and the U.S. As to this question the result of the analysis is that the chapter on Electronic Communications will be an important step towards facilitating trade in Electronic Communications services. At the same time some regulatory convergence will take place, but this convergence will not lead to a (full) harmonization of regulations. Rather the norm, also after TTIP negotiations will have been concluded successfully, will be mutual recognition of different regulatory regimes. Different regulations being the optimal policy response in different market settings will continue to exist. Moreover, it is very unlikely that such regulatory principles for the Electronic Communications sector are a vehicle for a race to the bottom in levels of consumer protection.}, language = {en} } @inproceedings{FredebeulKreinHaunert2008, author = {Fredebeul-Krein, Markus and Haunert, Martina}, title = {Assessing the effectiveness of price cap regimes for the regulation of fixed telephony markets: has it been successful in achieving competition? : preliminary draft / by Markus Fredebeul-Krein and Martina Haunert. 19th European Regional ITS Conference of the International Telecommunications Society, September 17-19, 2008 Rome, Italy}, year = {2008}, abstract = {1.
