&lt;br/&gt;Abstract: We study the implementation of reasonably efficient operator margin squeeze tests by National Regulatory Authorities in European telecommunications markets. We provide a theoretical framework in which we show how regulatory authorities deal with the asymmetries between the entrants and the incumbent by adjusting the equally efficient operator margin squeeze test used in competition policy. Using this framework, we build a benchmark of implementation choices by inspecting authorities' guidelines, market analyses and decisions. We find that some implementation choices are very similar across the authorities' decisions, whereas some others are dealt with quite heterogeneously.</description>

    <description>Title: Changing the rules: Applying a more economic approach to dynamic telecom markets
&lt;br/&gt;
&lt;br/&gt;Authors: Krancke, Jan; Vidal, Miguel; Fier, Andreas
&lt;br/&gt;
&lt;br/&gt;Abstract: Traditionally, neoclassical economics has been the guiding framework in the development of legislative and regulatory rules in the telecommunication markets. The regulatory perspective has long assumed a static environment. However, telecommunication markets have evolved into extremely dynamic, innovative and technology-driven markets. At the same time, economic theory has moved well beyond simple, static concepts of neo-classical analysis. Inter alia, Schumpeterian Economics, Institutional Economics and modern Industrial Organization provide a broader framework more suitable to analyze modern telecom markets. Drawing on an extended theoretical baseline and on major industry trends, we propose a more comprehensive framework for telecom regulation - the new regulatory pentagon - based on the cornerstones competition, investment and innovation, convergence and platformization, macroeconomics and growth and, lastly, commitment and credibility.</description>

&lt;br/&gt;
&lt;br/&gt;Abstract: In this paper, we study the adjustments made by National Regulatory Authorities to simple margin squeeze tests, in order to model a reasonably efficient operator. More precisely, by inspecting the possible differences between an entrant and an incumbent that would cause a market disadvantage for the former, we provide a formal economic framework that translates these ex-ante disadvantages into practical test adjustments. We identify five possible adjustments relevant to ex-ante margin squeeze tests, on the cost, the access charge, or the price parameters. We then review the implementation of margin squeeze tests by European telecommunications National Regulatory Authorities according to these adjustments, as to build a comparable benchmark of implementation choices.</description>

    <description>Title: Satisfaction and protection of individual mobile telecommunications consumers: Need for regulation?
&lt;br/&gt;

&lt;br/&gt;
&lt;br/&gt;Abstract: Mobile telecommunications markets have been studied primarily from the perspectives of mobile telecom operators, market organization and regulators. However, there have been few studies from the perspective of the private consumer, which is the object of this research. This paper is part of an ongoing project on the protection of individual mobile consumers. The main research questions of the project are whether, and to what extent, individual consumers of mobile telecommunications are satisfied or subject to dubious practices by mobile operators, possibly due to market failures, and whether improved regulation can increase the efficiency of the industry and the welfare of telecommunications consumers. The specific research question of this paper is how much customer satisfaction there is among private individual consumers of mobile telecommunications in Spain and what factors may be associated with this. Specifically, we formulate, estimate and interpret relationships between different aspects of satisfaction and its determinants. Some novelties of this paper are a new focus on individual consumers and the use of new data which convey high quality statistical information. We use cross-section data on 4953 individual consumers. We specify econometric models and estimate them using different techniques. Our data allow us to discriminate by operators, regions of residence (Autonomous Regions and provinces), gender, age and educational level, among others. Our results indicate that customers are less satisfied with the larger carriers like Telefónica and Vodafone, and more satisfied with smaller and newer operators. We measure the importance of each of the items of satisfaction to the overall satisfaction. We also estimate individual equations for each of the items of satisfaction and measure the importance of each of its determinants. Finally, we analyze the effects of the different types of complaints on each of the items of satisfaction.</description>
