Cartel Damages Claims and the Passing-On Defense

Posted by D. Daniel Sokol

Frank Verboven of Katholic University of Leuven Department of Economics and Theon van Dijk of Lexonomics address the issue of how to address Cartel Damages Claims and the Passing-On Defense.

ABSTRACT: We develop a general economic framework for computing cartel damages claims by purchaser plaintiffs. We decompose the lost profits from the cartel in three parts: the direct cost effect (or anticompetitive price overcharge), the pass-on effect and the usually neglected output effect. The pass-on effect is the extent to which the plaintiff passes on the price overcharge by raising its own price, and the output effect is the lost business resulting from this passing-on. We subsequently introduce various models of imperfect competition for the plaintiffs industry. This enables us to evaluate the relative importance of the cost, pass-on and output effects. We show that an adjusted passing-on defense (i.e. accounting for the output effect) is justified under a wide variety of circumstances, provided that sufficiently many firms in the plaintiff's market are affected by the cartel. We derive exact discounts to the direct cost effect, which depend on relatively easy-to-observe variables, such as the pass-on rate, the number of firms, the number of firms affected by the cartel, and/or the market shares. We finally extend our framework to assess the cartel's total harm, further demonstrating the crucial importance of the output effect. Our results are particularly relevant in light of the recent developments by U.S. and European antitrust authorities to make cartel damages claims more in line with actually lost profits.

EC Competition Law: A Critical Assessment

Posted by D. Daniel Sokol

Hart Publishing recently released the book EC Competition Law: A Critical Assessment.

ABSTRACT: This book, co-written by a team of European competition law specialists, offers critical perspectives on the whole range of issues in EC competition law. The book has two distinctive features: the first is that unlike similar works which present the law from either an enforcement agency or practitioner perspective in a fairly conventional manner, this work offers fresh, critical reflections on the state of the law. The second is that the authors are young academics, practitioners and administrators who have worked in the relevant fields and who are relatively new "voices" in the competition law literature. Drawn from diverse jurisdictions and professional backgrounds the authors bring a distinctively "European" feel (for instance not drawing exclusively on English language literature), and manage to introduce debates that have been taking place in the non-English language world, thereby assisting a more comprehensive dialogue in this field. The diversity in their professional backgrounds means that each chapter adopts a different perspective, with some chapters focusing on practical solutions to problems, and others exploring more general theoretical questions.
The textbook-like structure places the issues in their appropriate contexts and ensures that readers see how the discussion in each chapter links with the body of law as a whole.

The book is aimed at academic lawyers and practitioners, complementing existing textbooks and allowing the reader to extend his or her understanding of the subject and provide a quick source of reference to the main doctrinal debates on the subject, and offer fresh perspectives on the topics covered. The impact of EC competition law beyond Europe also means that this book will appeal to lawyers in the US, Australia, Canada and beyond.

How to Address "Invisible" Cartels

Posted by D. Daniel Sokol

Antitrust enforcers know they are out there, ripping off consumers.  Yet, how do you prove the existence of a cartel when it seems to be invisible.  Peter A.G. van Bergeijk of the Economic Policy Directorate Ministry of Economic Affairs answers this question in the Dutch context with his article On the Allegedly Invisible Dutch Construction Sector Cartel, which appears in the latest issue of the excellent Journal of Competition Law and Economics (a must read publication).

ABSTRACT: This paper considers an extensive cartel contamination of markets in the Dutch construction sector. Overwhelming legal evidence of bid rigging in this sector was obtained in 486 leniency applications in which complete secret accounts were submitted. I offer a case study and a broadly based post mortem of methodologies that were applied earlier to detect malfunctioning markets in the Netherlands, but failed to identify the construction sector as problematic. It is concluded that these studies were seriously flawed. Theoretical and empirical economic forensics (if properly applied) creates value for antitrust authorities in detection of antitrust violations directly, or by informing them where to look for direct evidence.

Competition in the Postal Sector

Posted by D. Daniel Sokol

One of my pet issues is competition in the postal sector (an issue that Rick Geddes and Greg Sidak have written about quite a bit).  The postal sector is among the most protected sectors in the world and antitrust agencies need to do more to ensure that there is increased competition.  Thankfully, DG Comp is up to the task.  A press release yesterday from DG Comp announed that the Commission has launched an investigation into France's unlimited state guarantee for its postal operator La Poste.  There might be less trans-Atlantic divergence if more efforts were made by trans-Atlantic enforcers to focus on one area in which there seems to be ideological convergence-- unjustified anti-competitive conduct on the part of the state.

Microsoft versus the Commission: With Great Power Comes Great Responsibility

Posted by D. Daniel Sokol

Philips Marsden of BIICL has a wonderfully titled piece on the impact of the EU Microsoft decision Microsoft versus the Commission: With Great Power Comes Great Responsibility.

ABSTRACT: In the Spiderman stories we are told that ‘with great power comes great responsibility’. The Court of First Instance has confirmed that dominant firms such as Microsoft have a special responsibility to help their rivals. The European Commission should be even more responsible when proceeding against dominant firms and issuing guidance on Article 82.

Revisiting Modernisation: The European Commission, Policy Change and the Reform of EC Competition Policy

Posted by D. Daniel Sokol

Change is in the air.  The leaves are turning colors here in beautiful Columbia and I needed to break out my winter coat for a trip to the supermarket last night.  Change is underway in antitrust as well.  In the EU, there has been a modernization and reform process for a number of years.  This is the subject of the new article Revisiting Modernisation: The European Commission, Policy Change and the Reform of EC Competition Policy by Hussein Kassim and Katheryn Wright, both of the University of East Anglia's Centre for Competition Policy. 

ABSTRACT: The modernisation of EC antitrust rules timed to coincide with the 2004 enlargement of the European Union is widely recognised as an historic and revolutionary reform.

According to the dominant view that has emerged in both law and political science, the change is to be explained in terms of the interest and ability of the European Commission to engineer a reform that, behind the guise of decentralisation to national authorities, has in practice extended its power and influence over the control of anti-competitive agreements. Drawing on original research, this paper contests the conventional wisdom and the image of the Commission as an imperialistic actor that underlines it. It argues that such a view dramatically overstates the Commission's power and that a more sophisticated explanation is required. First, the Commission was motivated more by changes in the thinking within an epistemic community of competition practitioners and lawyers than by an impulse to expand its authority. Second, contrary to the monolithic conception of the Commission on which the dominant view depends, the Commission was internally differentiated and the development of its reform proposals the product of internal negotiation and conflict, rather than the expression of an inner drive to expansionism.

Third, scrutiny reveals the Commission to be a constrained organisation, rather than a body able to re-write competition law autonomously.

Private Rights of Action in the EU - Lessons From the US Experience

Posted by D. Daniel Sokol

Gavil One of the heavyweights in US antitrust law, Andrew Gavil of Howard Law School (and author of the excellent casebook ANTITRUST LAW IN PERSPECTIVE: CASES CONCEPTS AND PROBLEMS IN COMPETITION POLICY along with Baker and Kovacic that you could purchase from our exclusive sponsor-- see the ad to the right of this post) has an insightful analysis on private rights of action worth reading titled The Challenges of Economic Proof in a Decentralized and Privatized European Competition Policy System: Lessons from the American Experience.

ABSTRACT: Since the announcement in late 2002 of the Modernization Plan, and continuing in 2005 with the release of the Green Paper on damages actions, the European Commission has been committed to a significant restructuring of the EU's approach to enforcing competition laws. Under the revised system as envisioned by the Commission, national competition authorities and private parties will assume a far greater role in supplementing the work of the Commission, which for 50 years has been the predominant competition policy enforcer in Europe. The goal is not only to produce a system of shared enforcement authority, but to promote the continued evolution in Europe of a "culture of competition, while avoiding the creation of a "culture of litigation. If national competition authorities and private parties accept this invitation, however, they are likely to face the same kinds of demands for substantial economic evidence from their national courts that the EC has faced from the Court of First Instance and the European Court of Justice in some of its most complex and challenging recent cases. This paper asks whether national level enforcers, public and private, will have the procedural and evidentiary tools necessary to respond to demands for such economic proof. Drawing on the Commission's recent experiences, as well as lessons from the U.S. experience, it asks whether the Green Paper's treatment of economic evidence is adequate given the importance that economic proof plays today in competition law cases. It then urges the Commission to devote additional attention to identifying and advocating reforms that will more actively facilitate the disclosure, development, and presentation of economic evidence. This paper particularly questions the Green Paper's preference for the use of court-appointed experts in lieu of party-secured expert witnesses. It argues that party and court-appointed experts can perform very different functions in competition law cases and should not be viewed as substitutes. Moreover, it suggests that the Green Paper may significantly underestimate the degree to which party-secured expert economic witnesses will be necessary if national level enforcers—public and private—are to be adequately equipped to meet the burdens of proof they will face. If national enforcers systematically find that they lack the procedural tools necessary to develop the economic evidence they need to meet those burdens, they will reduce or abandon their efforts to initiate competition law actions and it will be less likely that the promise of decentralization and privatization can be realized.

Airports, Aviation Competition and the Best Proposal on This Issue in Years

Posted by D. Daniel Sokol

Tomorrow I will be flying to a conference.  Invariably, I will be delayed at some point in my trip at the airport because of inefficient allocation of landing slots.  My heroes at the Economic Analysis Group of DOJ Antitrust, W. Tom Whalen, Dennis W. Carlton, Ken Heyer, and Oliver Richard have a proposal that is so simple, elegant and brilliant that of course Congress is likely to ignore it-- use slot auctions to promote more efficient use of gate capacity and promote competition.  They describe their proposal here.

I reproduce their proposal below:

Our preferred method to allocate scarce airport capacity is to auction slots for landings and takeoffs by time of day and to convey upon their purchasers well-defined property rights. Unlike access pricing, which may require the airport authority to continuously adjust prices, slot auctions require only that the airport authority set at the outset the total number of takeoffs and landings that the airport can accommodate in each time period under normal weather conditions. This approach plays to the strengths of airport authorities and the FAA, who have far greater expertise in determining an airport's capacity than they do at setting prices.

These slots should then be auctioned off through a market-based bidding process where each airline decides how much it would be willing to pay for each slot. The prices obtained for slots would reflect the degree of scarcity of capacity. The price could be close to zero at times of the day where capacity is great relative to demand, and it will be highest during periods where demand is at its greatest. Property rights would be awarded to the highest bidders, as long as acquisitions do not anti-competitively enhance market power. Prohibiting airlines from scheduling flights at times when they do not have the right to use one of the auctioned slots would efficiently address the problem of airport delay. Moreover, this market-based auction would allocate these scarce slots to their highest valued uses.

Slot holders should also be permitted to sell or lease slots in a secondary market. As service patterns and market conditions change, particular airlines may want to move some of their operations at slot constrained airports to different times, and the right to sell or lease would facilitate these types of efficient adjustments. Having well-defined property rights should encourage the development of a robust secondary market for slots, helping to ensure that slots are allocated to their highest valued uses.

An important component of our proposal is that general aviation users, such as corporate jets, be required to bid for access rights in competition with all others who wish to use them. Under the current system, a number of slots are reserved for general aviation aircraft. … The creation of priority rights through slots auctions may be used to further improve the efficiency of our current system. Weather issues at almost any airport in the system frequently force airlines to delay or cancel flights, as the FAA temporarily limits operations to respond to weather conditions. When those conditions arise, not all slot holders will be able to exercise the right conveyed by the slot, and the reduced capacity will have to be rationed. A question then arises as to how most efficiently to allocate that capacity among slot holders. One approach would be for the property rights of each slot to include a cancellation priority in the event of weather-related cancellations. This could be accomplished by ordering the slots in each time period, each with a different priority. As weather conditions required cancellations, slots would be canceled in order of their priority. Airlines could thus choose to pay a premium to acquire slots that are less likely to be canceled, and they would be able to advertise this high priority service to customers who value a lower probability of delay. Such tickets likely would command a premium. Moreover, during the delay period, the secondary market for slots would allow the airlines to efficiently transact slots for that day. In particular, an airline with a valuable departure could "buy up" to a higher priority position, while an airline with a priority slot but a less valuable flight on that day, could sell its priority position (though it could obviously not do so if it had sold its flight as a "high priority" one).

Significantly as well, under our proposal the slot auctions would generate revenues for the FAA and airport authorities. One possible use for the revenues generated by slot auctions would be to help fund expansion projects designed to increase capacity, such as the NextGen satellite navigation system the FAA is constructing to improve capacity utilization of air space. Indeed, it is difficult to justify subsidizing airlines by granting them for free rights to use valuable public assets whose sale at auction could generate considerable revenue.

Expert Economic Testimony, Economic Evidence and Asymmetry of Information in Antitrust Cases

Posted by D. Daniel Sokol

Expert testimony can make or break antitrust cases- just ask the people involved in the recent Whole Foods/Wild Oats merger.  Adding to the literature of how to think about economic experts is Juan David Gutiérrez of the law school of Pontificia Universidad Javeriana with his article Expert Economic Testimony, Economic Evidence and Asymmetry of Information in Antitrust Cases.

ABSTRACT: The objective of this document is to assess two questions that have a positive and normative nature respectively: 1) What incentives does the legal and institutional framework of the European Community (EC) and the United States (federal level) provide to the different agents involved in antitrust proceedings in regards to the use of expert economic testimonies? 2) What legal and social norms could provide appropriate incentives to the different agents involved in antitrust proceedings in order to align the use of expert economic testimonies with antitrust enforcement goals?

To answer the first research question and prepare the settings for the answer of the second question, the nature of the economic expertise applied in antitrust proceedings, its inherent difficulties (section 2), and the legal and institutional framework applied to them (section 3) are presented in detail.

Secondly, a general exposition of the problems posed by asymmetric information in theory (section 4.1) and concerning the relation between the adjudicator and the economic expert (section 4.2) is made, in order lay the foundations to identify the different factors that determine the incentives of the various “actors” in the proceedings (section 4.3).

Finally, to answer the second research question, the regulatory and non-regulatory features of US and EC enforcement systems are analyzed to identify which factors mitigate the information asymmetry problems. The different alternatives are presented in three different categories, namely, “evidentiary rules”, “procedural rules and institutional design” and “a market for experts and the academic community” (section 4.4).

The document contains six conclusions that may be summarized in the following statement: regarding expert economic testimonies, an antitrust enforcement system must aim at the minimization of its costs through the mitigation of the consequences of asymmetric information between the adjudicator and the expert. Therefore a cost-benefit analysis of the use of expert witnesses must take into account the incentives produced by the interaction among the different regulatory and non-regulatory features of the antitrust enforcement system.

What the Feds Taketh the States Giveth Back

Posted by D. Daniel Sokol

I remember a few years ago when Richard Posner called state antitrust enforcement "barnacles" to antitrust enforcement.  I thought of that statement when I read a recent article.  One big question to emerge from the overrule of Dr. Miles by Leegin  is what the states' response will be.  In the latest issue of the Antitrust Source, M. Russell Wofford, Jr. and Kristen C. Limarzi take a shot at prediction.  Their most important prediction "Predicting which states will reject Leegin’s approach is difficult, but states representing some of the largest economies in the country appear to number among those most likely to retain the Dr. Miles rule."
