Market Power, Economic Efficiency And The Lerner Index by Rolf Fare,Shawna Grosskopf,Dimitris Margaritis Pdf
The book uses distance functions, a generalization of the more familiar production function, as the theoretical and empirical tools to construct Lerner indexes of market power in both the input and output markets. The use of distance functions enables us to explicitly account for the effects of firm inefficiency and price markups in the evaluation of market power. The book focusses on the theory and provides a menu of applications to construct measures of firm efficiency and market power in the financial and public sectors.
Market Power and the Economy by Wallace C. Peterson Pdf
A situation in economics that is little short of scandalous is the almost total neglect by mainstream economics of the importance of power in economic affairs. Power in this context means the ability to bend market forces in one's favor, influencing and shaping key economic variables such as prices, wages, and other income determinants. As John Kenneth Galbraith as tutely observes: a dominant fact in economic life is the desire of people everywhere and in all circumstances to get control over their personal lives and their incomes-to escape from the "tyranny of the market. " Power is the means to this end. Ever since Adam Smith, economists have been fascinated by and lavish in their praise for the workings of the market. All modern textbooks are built around Smithian ideas about markets and the way the "invisible hand" works through competition for society's better ment. Yet one can search nearly in vain through leading texts, under graduate and graduate alike, for any reference to market or economic power. This is the situation in spite of the fact that the drive for power, the urge to get control over one's income, permeates the economy as much as does competition. This is a scandal! For a discipline that claims for itself the mantle of a science-one which wants to be accorded the same respect given the natural sciences-it is almost incomprehensible that it should ignore a major force at work in the real economic world.
Industrial Organization by Lynne Pepall,Dan Richards,George Norman Pdf
Pepall's Industrial Organization: Contemporary Theory and Empirical Applications, 5th Edition offers an accessible text in which topics are organized in a manner that motivates and facilitates progression from one chapter to the next. It serves as a complete, but concise, introduction to modern industrial economics. The text uniquely uses the tools of game theory, information economics, contracting issues, and practical examples to examine multiple facets of industrial organization. The fifth edition is more broadly accessible, balancing the tension between making modern industrial analysis accessible while also presenting the formal abstract modeling that gives the analysis its power. The more overtly mathematical content is presented in the Contemporary Industrial Organization text (aimed at the top tier universities) while this Fifth Edition will less mathematical (aimed at a wider range of four-year colleges and state universities.
Intertemporal Production Frontiers: With Dynamic DEA by Rolf Färe,Shawna Grosskopf Pdf
This book extends the efficiency literature to the case of intertemporal models. First, the authors introduce static network models which serve as building blocks for the intertemporal budgeting models and the dynamic models. Next, the authors devote two chapters to productivity measurements, which are considered as comparative static models. Intertemporal budgeting models and dynamic models are taken up subsequently. Each chapter, except the first, contains empirical applications.
Market definition and market power in the platform economy by Jens-Uwe Franck,Martin Peitz Pdf
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.
World Economic Outlook, April 2019 by International Monetary Fund. Research Dept. Pdf
After strong growth in 2017 and early 2018, global economic activity slowed notably in the second half of last year, reflecting a confluence of factors affecting major economies. China’s growth declined following a combination of needed regulatory tightening to rein in shadow banking and an increase in trade tensions with the United States. The euro area economy lost more momentum than expected as consumer and business confidence weakened and car production in Germany was disrupted by the introduction of new emission standards; investment dropped in Italy as sovereign spreads widened; and external demand, especially from emerging Asia, softened. Elsewhere, natural disasters hurt activity in Japan. Trade tensions increasingly took a toll on business confidence and, so, financial market sentiment worsened, with financial conditions tightening for vulnerable emerging markets in the spring of 2018 and then in advanced economies later in the year, weighing on global demand. Conditions have eased in 2019 as the US Federal Reserve signaled a more accommodative monetary policy stance and markets became more optimistic about a US–China trade deal, but they remain slightly more restrictive than in the fall.
Power Grid Operation in a Market Environment by Hong Chen Pdf
Covers the latest practices, challenges and theoretical advancements in the domain of balancing economic efficiency and operation risk mitigation This book examines both system operation and market operation perspectives, focusing on the interaction between the two. It incorporates up-to-date field experiences, presents challenges, and summarizes the latest theoretic advancements to address those challenges. The book is divided into four parts. The first part deals with the fundamentals of integrated system and market operations, including market power mitigation, market efficiency evaluation, and the implications of operation practices in energy markets. The second part discusses developing technologies to strengthen the use of the grid in energy markets. System volatility and economic impact introduced by the intermittency of wind and solar generation are also addressed. The third part focuses on stochastic applications, exploring new approaches of handling uncertainty in Security Constrained Unit Commitment (SCUC) as well as the reserves needed for power system operation. The fourth part provides ongoing efforts of utilizing transmission facilities to improve market efficiency, via transmission topology control, transmission switching, transmission outage scheduling, and advanced transmission technologies. Besides the state-of-the-art review and discussion on the domain of balancing economic efficiency and operation risk mitigation, this book: Describes a new approach for mass market demand response management, and introduces new criteria to improve system performance with large scale variable generation additions Reviews mathematic models and solution methods of SCUC to help address challenges posed by increased operational uncertainties with high-penetration of renewable resources Presents a planning framework to account for the value of operational flexibility in transmission planning and to provide market mechanism for risk sharing Power Grid Operations in a Market Environment: Economic Efficiency and Risk Mitigation is a timely reference for power engineers and researchers, electricity market traders and analysts, and market designers.
The Metaphysics of Market Power by George Raitt Pdf
Australian competition law has just emerged from a significant period of reform which has seen controversial changes to the legal test to distinguish between normal competitive conduct and conduct that should be condemned. The controversy continues, arguably because the traditional legal conception of market power does not provide a useful standard in real world markets. This important new book offers a radical interpretation of market power, based on the power to manipulate. Seeing it in this way allows for positive and normative standards within which to frame a legal theory of liability for misuse of that power. The book provides suggestions to improve the forensic assessment of conduct that should be condemned as misuse of market power.
Monopoly Power and Competition by Manuela Mosca Pdf
The innovative contributions of the Italian Marginalists - Pareto, Pantaleoni, De Viti de Marco and Barone, to economic theory have previously been overlooked. This is the first book to deal with the history of the theory of market power and of its relation with competition, focusing on the distinct intellectual tradition that is Italian Marginalist economic thought. Monopoly Power and Competition is a vital resource for historians of economic thought, as it explores a relatively untouched area of microeconomics that sheds light on the theories surrounding monopoly power and barriers to entry.

Issues in Industrial Economics by Satya R. Chakravarty Pdf
This book analyzes market power in technical terms and from different perspectives. In particular, it relates industrial market power under alternative market structures to concentration; looks at the effects of merger on market power; and evaluates its efficiency hypothesis. The technical terms and mathematics operations employed to discuss the results are explained in non-technical terms, and intuitive explanations of the mathematical results are given. Numerical illustrations of some of the results are provided using industry data.
Global Competition Law and Economics by Einer Elhauge,Damien Geradin Pdf
This is the second edition of the acclaimed text on global antitrust law. With markets becoming increasingly global, mergers requiring approval in several different jurisdictions, cartels in one nation affecting supply in others, and countries increasingly entering into treaties with each other about the content or enforcement of competition laws, antitrust law is now a truly global phenomenon. Modern antitrust law is also different because it now reflects an increasingly economic approach to analysing antitrust and competition policy. This innovative work is the only truly comparative and economically sophisticated casebook on the market. Addressed to students from all jurisdictions having competition laws, this casebook provides an in-depth analysis of the two major global antitrust regimes in the world, as well as a summary of selected national antitrust laws. As such it will also serve as a useful reference for practitioners, competition officials and policy-makers interested in competition law. In the four years since the first edition, the increased globalization of antitrust law has continued apace. China, the world's third largest economy after the EU and US, has adopted an antitrust law and other nations have modified and modernized their antitrust regimes. The EU has adopted a new EU Treaty, new EU guidelines on abuse of dominance, new EU guidelines on non-horizontal mergers, and new EU regulations and guidelines on vertical agreements. In the US there have been important new Supreme Court cases (the 2009 Linkline and 2010 American Needle decisions) and the appearance of a new economic approach in the revised 2010 U.S. Merger Guidelines. This new edition expands and updates the pioneering approach of the first edition, addressing new developments not only in the US and EU, but also in Australia, Brazil, Canada, Israel, Japan, South Africa, and South Korea, with expanded coverage of China's new antitrust law, and the antitrust laws of Argentina, Chile, Colombia, Egypt, India, Indonesia, New Zealand, Peru, Russia, Saudi Arabia, Singapore, Taiwan, Thailand, Turkey, and Venezuela. Praise for the first edition '...worthy of considerable praise...contains a vast collection of well-chosen material taking in a wide span of both antitrust and merger law issues. It is well written and clear throughout, particularly on the economic concepts, and provides incisive commentary and questions which inspire further study.' Peter Whelan, Cambridge Law Journal 'Enlightened law professors and law schools will best serve their students not by teaching national competition law but by adopting Global Competition Law and Economics...an excellent book for introductory courses in comparative competition law at either a graduate or undergraduate level.' Okeoghene Odudu, Common Market Law Review '...the best four-and-a-half centimetres of shelf-space that I have seen devoted to competition law and policy issues for a very long time”.' Yvonne van Roy, New Zealand Law Journal 'Free from the ideologically-driven perspective that can affect other antitrust casebooks, this is also the first casebook organized from inception with an eye directly on the global context...this book may be used in a classroom in Europe just as it will be used in the U.S. The result is a highly welcome contribution to the evolution of competition studies.' Judge Douglas Ginsburg '...this book is the only one on the market that is extremely well suited for use in a comparative antitrust law class...an extraordinarily teachable book that contains everything you might want to present...Finally, the comparative antitrust field has a standard textbook to use. And a wonderful standard it is.' Robert H Lande, University of Baltimore Law School
