Seminar paper from the year 2006 in the subject Politics - Topic: European Union, grade: Good, Ruhr-University of Bochum, course: MA (ECUE), language: English, abstract: Two-sided markets consist of two or more exclusive groups, present simultaneously on a single platform. They both need each other. In order to succeed the platform provider must ensure active participation of both groups. In the beginning these bazaars face chicken-and-egg problem, which should be solved, sometimes even by providing free chicken. These markets include some of the most important industries in new economy such as mobile telephony companies, free TV services, OS suppliers, software providers, gaming companies, credit card companies, auction sites etc. Ebay and amazon are good examples of two-sided markets. In such two-sided markets buyers and sellers first trade with the intermediary/ies so as to gain access to the functionalities of a platform and then trade with each other under oligopolistic conditions. In chapter 1 of this paper an attempt has been made to describe finer nuances of two-sided markets. Thereafter I proceed to discuss the various dynamics of two-sided markets in chapter 2. Two-sided firms differ from traditional industries and they follow totally different business economics. Marginal cost does not help them in deciding optimal price. Pricing policies and other business strategies must be formulated in such a way that it should ensure active interaction of both groups. Pricing strategy should get both sides on board and should also solve chicken-and-egg problem. Chapter 3 describes the pricing policy adopted by two-sided markets. Chapter 4 deals with relevance of two-sided markets for competition policy. Competition Authorities do not need different set of rules to regulate these industries. However Competition Authorities must consider various economic principles that influence pricing and investment decisions in two-sided markets. Chapter 5 concludes with various observations and suggestions.

Industrial Organization: Markets and Strategies provides an up-to-date account of modern industrial organization that blends theory with real-world applications. Written in a clear and accessible style, it acquaints the reader with the most important models for understanding strategies chosen by firms with market power and shows how such firms adapt to different market environments. It covers a wide range of topics including recent developments on product bundling, branding strategies, restrictions in vertical supply relationships, intellectual property protection, and two-sided markets, to name just a few. Models are presented in detail and the main results are summarized as lessons. Formal theory is complemented throughout by real-world cases that show students how it applies to actual organizational settings. The book is accompanied by a website containing a number of additional resources for lecturers and students, including exercises, answers to review questions, case material and slides.

Digital platforms controlled by Alibaba, Alphabet, Amazon, Facebook, Netflix, Tencent and Uber have transformed not only the ways we do business, but also the very nature of people's everyday lives. It is of vital importance that we understand the economic principles governing how these platforms operate. This book explains the driving forces behind any platform business with a focus on network effects. The authors use short case studies and real-world applications to explain key concepts such as how platforms manage network effects and which price and non-price strategies they choose. This self-contained text is the first to offer a systematic and formalized account of what platforms are and how they operate, concisely incorporating path-breaking insights in economics over the last twenty years.

With the rise of digital platforms and the natural tendency of markets involving platforms to become concentrated, competition authorities and courts are more frequently in a position to investigate and decide merger and abuse cases that involve platforms. This report provides guidance on how to define markets and on how to assess market power when dealing with two-sided platforms. DEFINITION Competition authorities and courts are well advised to uniformly use a multi-markets approach when defining markets in the context of two-sided platforms. The multi-markets approach is the more flexible instrument compared to the competing single-market approach that defines a single market for both sides of a platform, as the former naturally accounts for different substitution possibilities by the user groups on the two sides of the platform. While one might think of conditions under which a single-market approach could be feasible, the necessary conditions are so severe that it would only be applicable under rare circumstances. To fully appreciate business activities in platform markets from a competition law point of view, and to do justice to competition law’s purpose, which is to protect consumer welfare, the legal concept of a “market” should not be interpreted as requiring a price to be paid by one party to the other. It is not sufficient to consider the activities on the “unpaid side” of the platform only indirectly by way of including them in the competition law analysis of the “paid side” of the platform. Such an approach would exclude certain activities and ensuing positive or negative effects on consumer welfare altogether from the radar of competition law. Instead, competition practice should recognize straightforwardly that there can be “markets” for products offered free of charge, i.e. without monetary consideration by those who receive the product. ASSESSMENT The application of competition law often requires an assessment of market power. Using market shares as indicators of market power, in addition to all the difficulties in standard markets, raises further issues for two-sided platforms. When calculating revenue shares, the only reasonable option is to use the sum of revenues on all sides of the platform. Then, such shares should not be interpreted as market shares as they are aggregated over two interdependent markets. Large revenue shares appear to be a meaningful indicator of market power if all undertakings under consideration serve the same sides. However, they are often not meaningful if undertakings active in the relevant markets follow different business models. Given potentially strong cross-group external effects, market shares are less apt in the context of two-sided platforms to indicate market power (or the lack of it). Barriers to entry are at the core of persistent market power and, thus, the entrenchment of incumbent platforms. They deserve careful examination by competition authorities. Barriers to entry may arise due to users’ coordination failure in the presence of network effect. On two-sided platforms, users on both sides of the market have to coordinate their expectations. Barriers to entry are more likely to be present if an industry does not attract new users and if it does not undergo major technological change. Switching costs and network effects may go hand in hand: consumer switching costs sometimes depend on the number of platform users and, in this case, barriers to entry from consumer switching costs increase with platform size. Since market power is related to barriers to entry, the absence of entry attempts may be seen as an indication of market power. However, entry threats may arise from firms offering quite different services, as long as they provide a new home for users’ attention and needs.

The most important book on antitrust ever written. It shows how antitrust suits adversely affect the consumer by encouraging a costly form of protection for inefficient and uncompetitive small businesses.

This book compiles a set of pieces on the implications of the U.S. Supreme Court's ruling in Ohio et. al. v. American Express and the preceding litigation for the treatment of multisided platforms under U.S. antitrust law. The authors consider that the Supreme Court ruling provides valuable guidance for antitrust analysis in such markets.

As technology and interconnectivity have continued to flourish, so too has an important and complex form of enterprise: the platform. Services like Uber, Google Search, Hulu, and American Express cater to distinct but deeply-interdependent “sides” of customers that derive value or revenues from one another, such as the patients and care providers on a health insurance network, or the advertisers and consumers on a social media platform. A hallmark of “two-sided markets”--those in which platforms compete--is the need to get both sides on board. The platform cannot operate successfully without a critical mass of users on both sides, which is often challenging. Platform economics has important implications for antitrust policy, as the interdependence between sides adds new complexity to the evaluation of competitive effects. It becomes critical to discern whether a platform-defendant's conduct is plausibly necessary to get both sides on board. Until recently, courts had dealt with platform commerce only on an ad hoc basis, without articulating any general principles for evaluating restraints within two-sided markets. But the Supreme Court is poised to bring platform competition to antitrust's frontier, as its impending decision in American Express is likely to influence how core aspects of antitrust law and procedure are to be applied within two-sided markets moving forward. Against this backdrop, this article provides a broad analysis of antitrust in two-sided markets. It begins with a discussion of the distinctive features of platform commerce, explaining how they sometimes clash with established intuition and methods in antitrust. The bulk of the paper addresses a wide range of different antitrust concerns that might emerge from platform conduct, with emphasis on discerning when the market's two-sidedness might plausibly justify the practice in question (and when it probably doesn't). The balance of the paper then addresses the issues in American Express--both the market definition and burden shifting questions before the Supreme Court, and the substance of the original antitrust claim.
