Available in PDF, EPUB and Kindle. Book excerpt: We analyze a multi-period matching market where matching between agents is decided for each time period. To analyze this situation, we embed the situation into the framework of many-to-many matching with contracts where the contract includes the time period at which the matching occurs. While a general stability concept is already defined for the matching with contracts framework, in a multi-period matching model, a stable outcome may not exist when contracts exhibit complementarities across time periods. Thus, we define a weaker stability concept called temporal stability by taking into account the dynamic nature of the model. We provide sufficient conditions for the existence of a temporally stable outcome, including a corresponding substitutability condition, ordered substitutability, for the multi-period matching model.

Download or read book Online and Matching Based Market Design written by Federico Echenique and published by Cambridge University Press. This book was released on 2023-04-30 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rich, multi-faceted and multi-disciplinary field of matching-based market design is an active and important one due to its highly successful applications with economic and sociological impact. Its home is economics, but with intimate connections to algorithm design and operations research. With chapters contributed by over fifty top researchers from all three disciplines, this volume is unique in its breadth and depth, while still being a cohesive and unified picture of the field, suitable for the uninitiated as well as the expert. It explains the dominant ideas from computer science and economics underlying the most important results on market design and introduces the main algorithmic questions and combinatorial structures. Methodologies and applications from both the pre-Internet and post-Internet eras are covered in detail. Key chapters discuss the basic notions of efficiency, fairness and incentives, and the way market design seeks solutions guided by normative criteria borrowed from social choice theory.
Download or read book Microeconomic Foundations II written by David M. Kreps and published by Princeton University Press. This book was released on 2023-01-03 with total page 799 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cutting-edge introduction to key topics in modern economic theory for first-year graduate students in economics and related fields Volume II of Microeconomic Foundations introduces models and methods at the center of modern microeconomic theory. In this textbook, David Kreps, a leading economic theorist, emphasizes foundational material, concentrating on seminal work that provides perspective on how and why the theory developed. Because noncooperative game theory is the chief tool of modeling and analyzing microeconomic phenomena, the book stresses the applications of game theory to economics. And throughout, it underscores why theory is most useful when it supports rather than supplants economic intuition. Introduces first-year graduate students to the models and methods at the core of microeconomic theory today Covers an extensive range of topics, including the agency theory, market signaling, relational contracting, bilateral bargaining, auctions, matching markets, and mechanism design Stresses the use—and misuse—of theory in studying economic phenomena and shows why theory should support, not replace, economic intuition Includes extensive appendices reviewing the essential concepts of noncooperative game theory, with guidance about how it should and shouldn’t be used Features free online supplements, including chapter outlines and overviews, solutions to all the problems in the book, and more

Download or read book Value Solutions in Cooperative Games written by Roger A. McCain and published by World Scientific. This book was released on 2013 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces new concepts for cooperative game theory, and particularly solutions that determine the distribution of a coalitional surplus among the members of the coalition. It also addresses several generalizations of cooperative game theory. Drawing on methods of welfare economics, new value solutions are derived for Non-Transferable Utility games with and without differences of bargaining power among the members of the coalition. Cooperation in intertemporal games is examined, and conditions that permit the reduction of these games to games in coalition function form are outlined. Biform games and games that combine non-cooperative search and matching of coalition members with cooperative solutions (i.e., efficient contracts) within the coalition are considered.
Download or read book Market definition and market power in the platform economy written by Jens-Uwe Franck and published by Centre on Regulation in Europe asbl (CERRE). This book was released on 2019-05-08 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Auctioning Public Assets written by Maarten Christiaan Wilhelmus Janssen and published by Cambridge University Press. This book was released on 2004 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many countries all over the world, governments are privatising firms that were previously under public control. This is happening, for example, in public utility sectors such as gas, water and electricity, in transport sectors (such as rail and metro) and in radio and telephony. This book provides an overview of the economic issues that are involved in this transfer of ownership of public assets. Combining a theoretical framework with a set of case studies of recent sales of state-owned assets from Europe and the USA, it asks which sort of allocation mechanism can a government adopt? Which is most suited to a particular sale? And how will the choice of allocation mechanism affect future market outcomes? With contributions from international experts, this book offers an accessible introduction to auction theory and an invaluable, non-technical analysis of existing knowledge. It will be of interest to students, non-specialists and policy-makers alike.

Download or read book Two Sided Matching written by Alvin E. Roth and published by Cambridge University Press. This book was released on 1992-06-26 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-sided matching provides a model of search processes such as those between firms and workers in labor markets or between buyers and sellers in auctions. This book gives a comprehensive account of recent results concerning the game-theoretic analysis of two-sided matching. The focus of the book is on the stability of outcomes, on the incentives that different rules of organization give to agents, and on the constraints that these incentives impose on the ways such markets can be organized. The results for this wide range of related models and matching situations help clarify which conclusions depend on particular modeling assumptions and market conditions, and which are robust over a wide range of conditions. 'This book chronicles one of the outstanding success stories of the theory of games, a story in which the authors have played a major role: the theory and practice of matching markets ... The authors are to be warmly congratulated for this fine piece of work, which is quite unique in the game-theoretic literature.' From the Foreword by Robert Aumann
Download or read book The Handbook of Market Design written by Nir Vulkan and published by OUP Oxford. This book was released on 2013-08-29 with total page 706 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economists often look at markets as given, and try to make predictions about who will do what and what will happen in these markets. Market design, by contrast, does not take markets as given; instead, it combines insights from economic and game theory together with common sense and lessons learned from empirical work and experimental analysis to aid in the design and implementation of actual markets In recent years the field has grown dramatically, partially because of the successful wave of spectrum auctions in the US and in Europe, which have been designed by a number of prominent economists, and partially because of the increase use of the Internet as the platform over which markets are designed and run There is now a large number of applications and a growing theoretical literature. The Handbook of Market Design brings together the latest research from leading experts to provide a comprehensive description of applied market design over the last two decades In particular, it surveys matching markets: environments where there is a need to match large two-sided populations to one another, such as medical residents and hospitals, law clerks and judges, or patients and kidney donors It also examines a number of applications related to electronic markets, e-commerce, and the effect of the Internet on competition between exchanges.
