Revisiting Concentration in Food and Agricultural Supply Chains: The Welfare Implications of Market Power in a Complementary Input Sector
Metin Cakır (University of Minnesota) and James Nolan (University of Saskatchewan) are Revisiting Concentration in Food and Agricultural Supply Chains: The Welfare Implications of Market Power in a Complementary Input Sector.
ABSTRACT: The use of complementary inputs is a key characteristic of the production process in many food related industries. In this article we explore how market power in a complementary input sector compares to the exertion of market power in a downstream sector for both producer and consumer welfare, as well as for policy. We develop a model of a homogenous product market that encompasses both bilateral and complementary relationships. The model focuses on the primary input sector and allows for exertion of market power by both complementary input suppliers and downstream firms. We use comparative statics analyses and numerical simulations to study the economic equilibrium under different scenarios of market power exertion. With respect to the welfare of primary input suppliers, our main finding is that market power exercised by the supplier of a complementary input generates greater negative effects than the same level of mark! et power exercised by the downstream firms. We provide a discussion of the implications of the results for policy in the context of current problems within the Canadian grain handling and transportation system.
The optimal short-term management of flexible nuclear plants in a competitive electricity system as a case of competition with reservoir
Pascal Gourdel (CES) and Maria Lykidi (CES) explore The optimal short-term management of flexible nuclear plants in a competitive electricity system as a case of competition with reservoir.
ABSTRACT: In many countries, the electricity systems are quitting the vertically integrated monopoly organization for an operation framed by competitive markets. It therefore questions how flexible nuclear plants capable of load-following should be operated in an open market framework. A number of technico-economical features of the operation of flexible nuclear plants drive our modelling complex which makes difficult to determine the optimal management of the nuclear production within our model. In order to examine the existence of an equilibrium and calculate it, we focus on a short-term (monthly) management horizon of the fuel of nuclear reactors. The marginal cost of nuclear production being (significantly) lower than that of thermal production induces a discontinuity of producer's short-term profit. The problem of discontinuity makes the resolution of the optimal short-term production problem extremely complicated and even le! ads to a lack of solutions. That is why it is necessary to study an approximate problem (continuous problem) that constitutes a "regularization" of our economical problem (discontinuous problem). Its resolution provides us with an equilibrium which proves the existence of an optimal production trajectory.

Florian LEON (CERDI) analyzes Bank Competition and Credit Constraints in Developing Countries: New Evidence.
ABSTRACT: Bank Competition and Credit Constraints in Developing Countries: New Evidence Whether competition helps or hinders small firms' access to finance is in itself a much debated question in the economic literature and in policy circles, especially in the developing world. Economic theory offers conflicting predictions and empirical contributions provide mixed results. This paper considers the consequences of interbank competition on credit constraints using firm level data covering 70 developing and emerging countries. In addition to the classical concentration measures, competition is assessed by computing three non-structural measures (Lerner index, Boone indicator, and H-statistics). The results show that bank competition alleviates credit constraints, while bank concentration measures are not robust predictors of a firm's access to finance. Findings highlight that bank competition not only leads to less severe loan approval decisions but also reduces borrowers' discouragement. In addition, a secondary result of this paper documents that banking competition enhances credit availability more by reducing prices than by increasing relationship lending.
Ralf Dewenter (Helmut Schmidt University, Hamburg) and Jurgen Rosch, (Helmut Schmidt University, Hamburg) describe Net Neutrality and the Incentives (Not) to Exclude Competitors.
ABSTRACT: This paper analyses the incentives of a vertical integrated Internet service provider (ISP) to block competitors from content markets. Using a simple model we find that the ISP does not block competing content providers as long as the contents are differentiated sufficiently. Exclusion only takes place when the competitor offers perfect homogeneous content and the ISP has a local monopoly over its Internet access customers or if network effects are strong. In this case, however, the abuse of market power can at least in Europe be prohibited by competition authorities. That is, according to our model there is no need for a regulation of net neutrality.
Bjorn Bartling, Manuel Grieder and Christian Zehnder argue to Let the market decide: an experimental study of competition and fairness.
ABSTRACT: Is competition perceived as a fair procedure? We report data from laboratory experiments where a powerful buyer can trade with one of several sellers. Sellers who feel shortchanged can engage in counterproductive behavior to punish the buyer. We find that the same unfavorable terms of trade trigger significantly less punishment if the buyer uses a competitive auction to determine the terms of trade than if she uses her authority to dictate the same terms directly. Our results inform the debate on the fairness of market outcomes by showing that the use of a competitive procedure can, by itself, affect how people judge unequal distributive outcomes.
Pedro Bento (West Virginia University, College of Business and Economics) explores Patent Protection as a Tax on Competition and Innovation.
ABSTRACT: I introduce patents into a general equilibrium model of innovation, where innovators choose between creating a new product market and competing in an existing market. Patent holders demand royalties from sequential innovators, but are constrained by the ability of innovators to work around patents. I show patent protection acts as a net tax on sequential innovators, reducing both competition and productivity growth. Calibrated to match moments from U.S. data, the model predicts that eliminating patent protection in the U.S. would generate a 23% increase in steady-state productivity growth as well as an increase in welfare equivalent to that from a 16% increase in annual consumption. I test several implications of the model using both U.S. and cross-country data. Consistent with the model, the data suggests an increase in the strength of patent protection reduces both productivity growth and the average quality of innovations.

Shan Jiang, University of International Business and Economics (UIBE) School of Law and D. Daniel Sokol, University of Florida - Levin College of Law discuss Resale Price Maintenance in China: An Economic Perspective.
ABSTRACT: This article analyzes resale price maintenance (RPM), its economic principles, and its application in the United States, Europe and China. The application of RPM varies across each of these three jurisdictions. In China, there are competing economic goals, no clear standard (per se illegality versus rule of reason) and case outcomes that do not necessarily fully embrace an economic based approach. We identify those areas in Chinese antitrust jurisprudence that will shape enforcement and offer an economic approach that allows for internal consistency for decision-making.

Pedro Bento (West Virginia University, College of Business and Economics) analyzes Competition as a Discovery Procedure: Schumpeter Meets Hayek in a Model of Innovation.
ABSTRACT: I incorporate an insight of Friedrich Hayek - that competition allows a thousand flowers to bloom, and discovers the best among them - into a model of Schumpeterian innovation. Firms face uncertainty about the optimal direction of innovation, so more innovations implies a higher expected value of the `best' innovation. The model accounts for two seemingly contradictory relationships reported in recent empirical studies - a positive relationship between competition and industry-level productivity growth, and an inverted-U relationship between competition and firm-level innovation. Notwithstanding the positive relationship between competition and growth, I find antitrust policy reduces industry-level growth.
M. Cecilia Bustamante (LSE) and Andres Donangelo (University of Texas) address Product Market Competition and Industry Returns.
ABSTRACT: This paper shows that product market competition has two opposing effects on asset returns. The first relates to the procyclical nature of the value destruction from expansion of competitors, which lowers exposure to systematic risk in more competitive industries. The second is related to the narrower profit margins due to competition, which increase exposure to systematic risk. We find that the first effect dominates the second, so that firms in more competitive industries generally earn lower asset returns. Our results are robust to using five alternative measures of competition and to controlling for the sample selection bias of publiclylisted firms.

Stefan Lorenczik (Energiewirtschaftliches Institut an der Universitaet zu Koeln) Raimund Malischek (Energiewirtschaftliches Institut an der Universitaet zu Koeln) and Johannes Truby (Energiewirtschaftliches Institut an der Universitaet zu Koeln) are Modeling Strategic Investment Decisions in Spatial Markets.
ABSTRACT: Markets for natural resources and commodities are often oligopolistic. In these markets, production capacities are key for strategic interaction between the oligopolists. We analyze how different market structures influence oligopolistic capacity investments and thereby affect supply, prices and rents in spatial natural resource markets using mathematical programing models. The models comprise an investment period and a supply period in which players compete in quantities. We compare three models, one perfect competition and two Cournot models, in which the product is either traded through long-term contracts or on spot markets in the supply period. Tractability and practicality of the approach are demonstrated in an application to the international metallurgical coal market. Results may vary substantially between the different models. The metallurgical coal market has recently made progress in moving away from long-term! contracts and more towards spot market-based trade. Based on our results, we conclude that this regime switch is likely to raise consumer rents but lower producer rents. The total welfare differs only negligibly.
Mark Amstrong, Oxford has a new paper on Search and Ripoff Externalities.
ABSTRACT: This paper surveys models of markets in which some consumers are "savvy" while others are not.� We discuss when the presence of savvy consumers improves the deals available to non-savvy consumers in the market (the case of search externalities), and when the non-savvy fund generous deals for savvy consumers (ripoff externalities).� We also discuss when the two groups of consumers have aligned or divergent views about market interventions.� The analysis covers two overlapping families of models: those which examine markets with price/quality dispersion, and those which exhibit forms of consumer hold-up.
Jan Bouckaert, University of Antwerp - Department of Economics and Peter M. Kort, Tilburg University - Department of Econometrics & Operations Research; Tilburg University - Center for Economic Research (CentER) offer Merger Incentives and the Failing Firm Defense.
ABSTRACT: The merger incentives between profitable firms differ fundamentally from the incentives of a profitable firm to merge with a failing firm. We investigate these incentives under different modes of price competition and Cournot behavior. Our main finding is that firms strictly prefer exit of the failing firm to acquisition. This result may imply that other than strategic reasons, like economies of scale, must be looked for to understand why firms make use of the failing firm defense. However, when products are sufficiently heterogenous, we find that (i) the failing firm defense can be welfare enhancing and (ii) a government bail‐out increases total welfare when the number of firms is sufficiently low.
Search, Price Dispersion, and Local Competition: Estimating Heterogeneous Search Costs in Retail Gasoline Markets
Mitsukuni Nishida (The Johns Hopkins Carey Business School) and Marc Remer (Economic Analysis Group, U.S. Department of Justice) analyze Search, Price Dispersion, and Local Competition: Estimating Heterogeneous Search Costs in Retail Gasoline Markets.
ABSTRACT: Information frictions play a key role in a wide array of economic environments and are frequently incorporated into formal models as search costs. Yet, as search costs are typically unobserved, little empirical work investigates the determinants of the distribution of consumer search costs and the implications for policy. This paper explores the sources of heterogeneity in consumer search costs and how this heterogeneity and market structure shape firms' equilibrium pricing and consumers' search behavior in retail gasoline markets. We estimate the distribution of consumer search costs using price data for a large number of geographically isolated markets across the United States. The results demonstrate that the distribution of consumer search costs varies significantly across geographic markets and that market and population characteristics, such as household income, explain some of the variation. Policy counterfactuals! suggest that the shape of the consumer search cost distribution has important implications for both government policy and firms' strategic pricing behavior. The experiments reveal that (1) the search cost distribution needs to be sufficiently heterogeneous to generate equilibrium price dispersion, and (2) the market-level expected price paid decreases in the number of firms, but consumers with high search costs may be worse off from an increased number of firms.

Ariel Ezrachi has come out with the FOURTH EDITION of EU Competition Law An Analytical Guide to the Leading Cases.
BOOK ABSTRACT: This book is the fourth edition of a highly practical guide to the leading cases in European Competition Law, focusing primarily on Article 101 TFEU, Article 102 TFEU and the European Merger Regulation. In addition it explores the public and private enforcement of Competition Law, the intersection between Intellectual Property Rights and Competition Law and the application of Competition Law to State action. Each chapter outlines the relevant laws, regulations and guidelines for each of the topics. Within this framework, cases are reviewed in summary form, accompanied by analysis and commentary.
Henri De Belsunce, Max Planck Institute for Innovation and Competition asks Do More Patents Mean Less Entry?
ABSTRACT: This paper investigates the entry decision of a firm into a market that is protected by a patent. It shows how entrants use the possibility to study existing prior art before taking their entry decision. Studying prior art reduces the information asymmetry that arises due to the fact that patent strengths are private information. The paper analyses the incumbent’s incentives to pursue a raising rivals’ cost strategy by excessive patenting. The application of the model shows that the treble damages doctrine reduces the incentives for an incumbent to patent excessively.
Daryl Lim, John Marshall Law has a paper on Standard Essential Patents, Trolls and the Smartphone Wars: Triangulating the End Game.
ABSTRACT: Few legal issues in recent years have captured the public’s attention more powerfully than litigation over standard essential patents (“SEPs”). This Article explains how SEP litigation overlaps with two other major centers of patent litigation – litigation involving smartphones and patent assertion entities (“PAEs”). It observes that attempting to pre-empt patent hold-ups by imposing blanket ex ante disclosure obligations and royalty caps on standard setting organizations (“SSOs”) is misdirected and counterproductive. Instead, the solution lies in clear and balanced rules to determine “fair, reasonable and non-discriminatory” (FRAND) royalties and injunctive relief. This solution will help parties make more realistic assessments of their options and help adjudicators resolve SEP disputes.
Correctly framed, implementers bear the burden of proving the breach of a FRAND commitment. FRAND royalties should, in the absence of comparable licenses, focus on apportioning the profits based on the relative importance of the patented technology in the covered product. Royalties should be measured at the time the standard is set but generally should not be discounted for the possibility of invalidity and non-infringement. Discriminatory licenses can be hard to detect, but targeted initiatives and improved transparency would make the task easier. Injunctions should be granted based the wording and intent of the relevant FRAND commitment, conduct of the parties, and proof that the technology drove the sales of the component or product on which the relief is sought. More broadly, courts must understand both the limits and opportunities of the antitrust and patent laws. While useful in arresting ex ante misconduct, antitrust is largely irrelevant to SEP litigation; patent law has a role in both improving patent quality and deterring vexatious litigation.
The ABA Section of Antitrust Law has published Frequently Asked Antitrust Questions, Second Edition.
BOOK ABSTRACT: Frequently Asked Antitrust Questions is a tremendous resource for practitioners who need quick, plain language answers to questions that arise every day for every business. The book is useful both for the non-expert who needs easy access to the basic rules of the road and lawyers with significant experience in antitrust law who need to respond quickly and efficiently to questions from clients. This revision includes two new chapters addressing emerging issues in the areas of intellectual property and antitrust compliance. The prior edition's discussion of trade associations has also been expanded and now makes up its own chapter. Other chapters also contain expanded material, including additional references and footnotes for practitioners who need to delve deeper into specific issues. Expanded topics include:
- communications with competitors,
- dealing with antitrust authorities in the United States and abroad,
- the Robinson-Patman Act and other pricing issues,
- vertical arrangements between customers and suppliers, and more.
Even with this increased content, however, Frequently Asked Antitrust Questions remains a user-friendly and unique go-to resource for attorneys of all experience levels.

Market Structure Control and Restriction of Anticompetitive M&As and 'Concentration' of Enterprises' Market Power in BRICS Countries: General Approaches (Asia - China and India, Euro-Asia - Russia and Africa - South Africa - In Focus)
Ksenia Belikova, Peoples' Friendship University of Russia discusses Market Structure Control and Restriction of Anticompetitive M&As and 'Concentration' of Enterprises' Market Power in BRICS Countries: General Approaches (Asia - China and India, Euro-Asia - Russia and Africa - South Africa - In Focus).
ABSTRACT: The articles represents a research of general approaches of BRICS countries legislation and legal order to counteraction against such an anticompetitive market strategy as abuse of dominant market power in legal orders of China, India, Russia and South Africa. The author pays particular attention to current legislation of BRICS countries in the field of competition protection with regard to provisions related to market structure control and restrictions of anticompetitive mergers & acquisitions (further on - M&As) and “concentration” of enterprises' market power control fixed by Asian (China and India), Euro-Asian (Russia) and African (South Africa) legal orders. The analysis of substantial contents of laws on competition and monopolies of the above mentioned BRICS countries and relevant case law shows the existence of a number of conventional generally acknowledged (unified) provisions and norms. At the same time there are specific features making them different. These generally acknowledged provisions and peculiarities will be in focus in the article.
