      <description>Title: Assessing access problems in online media platforms
Authors: Graef, Inge; Wahyuningtyas, Sih Yuliana; Valcke, Peggy
Abstract: Online media platforms have the characteristics of a particular type of market known as 'multi-sided'. These businesses create value by bringing advertisers and users together. Access to user data is critical to this process. On the basis of economic literature, the features of multi-sided platforms will be discussed. It will be argued that the characteristics of multi-sided platforms increase the likelihood that successful companies become dominant due to the existence of indirect network effects. In these circumstances, dominant platforms may foreclose competition by raising barriers to entry in the large collections of user data. This may give rise to access problems for competitors and new entrants that need access to data gathered by dominant platforms in order to provide competing or complementary services. A comparative legal analysis will be used to assess the standards that apply in the United States (US) and the European Union (EU) for finding liability for refusals to deal under antitrust or competition law. The private antitrust cases that have already occurred regarding access to user data in the US show that the scope of applicability of the essential facilities doctrine is very limited after the judgment of the Supreme Court in Trinko. Although the European Commission and the Court of Justice seem to be willing to accept liability for a refusal to deal more easily than their US counterparts, high legal hurdles still have to be met under the essential facilities doctrine in the EU. Nevertheless, there are scenarios in which liability for refusals to give access to data will likely be accepted in the EU.</description>

      <description>Title: A research on ICT standards management based on standards reusability analysis
Authors: Lee, Younkwan; Cha, H. K.; Park, W.; Ha, S. W.; Lee, B. N.; Park, K.
Abstract: Standards are those generally agreed through repetitive use. They also make products and services more reliable. Thus, when developing standards, one should at first be aware of what the market actually needs not what the developers and providers want. If not, unnecessary standards will eventually end up being unused and dismissed. In this sense, standards developed primarily based on users' point of view are much more reusable. As information and communication technology (ICT) being accelerated these days, the number of standardisation activities has been dramatically increased and a great number of group and international standards has been developed all over the world. Therefore, Standards Developing Organisations (SDOs) follow routine maintenance procedures on their developed standards in order to assure their quality. In this paper, the authors propose a methodology for managing developed standards to enhance standards reusability in terms of standards development, maintenance, and management.</description>

      <description>Title: Investment strategies for different actors in indoor mobile market: "In view of the emerging spectrum authorization schemes"
Authors: Widaa, Ashraf Awadelakrim; Markendahl, Jan; Ghanbari, Amirhossein
Abstract: The regulatory landscape is changing towards more flexible spectrum management schemes. Such schemes are expected to make additional spectrum resources available and lower the spectrum access barriers. Emerging spectrum authorization schemes such as secondary access (TV White Space) and Licensed Shared Access (LSA) are expected to open doors for new actors rather than traditional MNOs to access licensed spectrum resources at reasonable costs. These schemes will allow actors such as Facility Owners (FO), Mobile Virtual Network Operators (MVNO) and Internet Service Providers (ISPs) to invest in indoor mobile network infrastructure. These actors can act as Local Network Operators (LNO) and build their business models around provisioning of mobile services in locations where there seems to be a hole or lack of service coverage in a particular area within the mobile network operators (MNOs) service footprint. This paper highlights the differences between indoor deployment and outdoor deployment in the light of the available spectrum bands to be used and the possible business models for MNOs and LNOs. In short, the possible investment strategies for provisioning indoor mobile services vary between MNOs and LNOs cases due to economic and regulatory aspects surrounding them. The main finding in this study indicates that the willingness of MNOs to invest in dedicated indoor solutions is driven by the balance between the potential revenues and the deployment cost. Moreover MNOs have more spectrum and investment options compared to LNOs who must bond their investment strategies to the available spectrum resources (i.e. the regulations of spectrum access).</description>

      <description>Title: Residential mobile phone users complaints' in Spain
Authors: Pérez-Amaral, Teodosio; Gijón, Covadonga; Garín-Muñoz, Teresa; López, Rafael
Abstract: Consumer satisfaction is a key determinant of customer retention, profitability of operators, consumer welfare and a strategic variable for competition and international comparisons. Spain's mobile customer satisfaction is the lowest in the European Union according to recent EU studies (SMREC, 2013). Consumer complaints are numerous according to official statistics. In turn, consumer complaints (and how well they are dealt with) influence customer satisfaction and retention. This paper analyzes the determinants of the different types of complaints filed by residential consumers in Spain using the survey CIS (2009) and the report Ministerio de Industria (2012a). The first survey uses disaggregated information on 4,249 residential consumers while the report summarizes the complaints received by the Ministry of Industry's Telecommunications Customer Service Office. Econometric models are specified and estimated to quantify the effects. The results are used to characterize the profiles of typical complainers as well as the possible existence of a complaints divide due to income, age or education. Finally, policy recommendations are proposed to improve customer satisfaction and diminish the reasons for filing complaints.</description>
