A Ezrachi and David Gilo, 'Are Excessive Prices Really Self-Correcting?' (2009) Journal of Competition Law & Economics

A Ezrachi, 'Buying Alliances and Input Price Fixing – In Search of a European Enforcement Standard ' (2012) Journal of Competition Law & Economics [...]

This paper considers the welfare implications of input price fixing and the enforcement standard to be applied to these arrangements. It explores the way in which European competition law approaches input price fixing, the scope of the object-based approach and the instances in which effects-based analysis may be used in the appraisal. In doing so, the paper sets to clarify the legal approach to price fixing of procured input. It outlines a possible benchmark for the assessment of input price fixing, with the aim of sharpening the dividing line between instances which restrict competition by object, and those which necessitate consideration of effects.

A Ezrachi and M Maggiolino, 'European Competition Law, Compulsory Licensing and Innovation' (2012) Journal of Competition Law and Economics [...]

This article explores the interface between competition law and intellectual property rights (IPRs) in the context of compulsory licensing. It considers how European competition law has been applied to limit the protection awarded to IPR holders and reflects on the remedy of compulsory licensing. In doing so, the article considers how current policies may affect innovation and welfare. In our analysis, we consider two questions that are inter-linked. The first relates to the threshold for finding that a refusal to license IPRs amounts to an abuse of a dominant position. We consider whether the current European threshold for intervention is adequate and clear. Our analysis illustrates that the use of competition law as an external balancing tool has gradually eroded the protection conferred by IPR. Furthermore we show that the European Commission’s Guidance Paper on Article 102 of the Treaty on the Functioning of the European Union (TFEU)1 has contributed to this trend. We argue that these processes have blurred the principles which limit the application of competition law to IPR, creating a potentially detrimental effect on competition and innovation. We consider the characteristics of the compulsory license remedy and reflect on its adequacy in resolving competitive and innovative injuries caused by the refusal to license. In doing so, we review the aims of compulsory licensing, as well as its advantages and disadvantages. We then propose an offense-remedy distinction, which allows substantive analysis of abuse, independent of the remedy. This method enables antitrust authorities to evaluate the offense with less risk of reaching a conclusion that is based on a false positive.

A Ezrachi and Gilo, 'Excessive Pricing, Entry, Assessment and Investment – Lessons from the Mittal Litigation' (2010) 76:3 Antitrust Law Journal [...]

The role of antitrust in curtailing excessive prices has long been a contentious area. Consequently, the charging of excessive prices has been subjected to diverse levels of enforcement across the world.1 U.S. antitrust law, for example, does not encompass the charging of high prices as such,2 and was held not to “condemn the resultant of those very forces which it is its prime object to foster: finis opus coronat.”3 By contrast, competition laws in other jurisdictions provide for the condemnation of excessive or unfair pricing. Such is the case under EU competition law,4 the competition provisions in the European Member States,5 and in other jurisdictions across the world.6 But even among those competition regimes which do intervene against the charging of excessive prices as such, one may identify different levels of enthusiasm for doing so. In Europe, for example, recent years have witnessed a restrained approach by the European Commission7 but a more proactive approach by some of the competition authorities of the Member States.8 Varying levels of intervention reflect a controversy as to the merit of prohibiting excessive pricing. Three main grounds are often used to justify non-, or limited-, intervention: (1) intervention is not necessary, as high prices would be competed away by new entry, attracted by the ex-cessive price; (2) there are practical difficulties in speculating what a price would have been had there been competition and in determining the excessiveness of the prices actually charged; and (3) enforcement which targets excessive prices may chill innovation and investment.9 To illustrate the difficulties of assessment and to question some of the justifications that are used to rationalize non-intervention, this article reviews the recent litigation in South Africa related to alleged excessive pricing by Mittal Steel.10 We use the decisions of the South African Competition Tribunal and the South African Competition Appeal Court as a case study to highlight both the complexity of, and possible merit in, antitrust intervention against excessive pricing. Our analysis focuses on the three grounds for non-intervention. First, with respect to the self-correcting nature of excessive prices, we illustrate how excessive prices, in and of themselves, do not attract new entry, when potential entrants are either informed or uninformed about their post-entry profits. Referring to our previous work on this subject,11 we question the South African Competition Tribunal’s holding in the Mittal case with respect to the prerequisite conditions for intervention against excessive pricing. Second, we consider how the difficulties of assessing what is an excessive price affected the outcome in the Mittal litigation. Without underestimating these difficulties, we consider how they may be alleviated in certain cases through reasonable methods for inferring what may constitute an excessive price. Third, while acknowledging the possible validity of concerns about chilling ex ante investment, we outline instances in which these concerns should not serve to support nonintervention. It should be stressed that this article does not advocate across-theboard intervention. It does, however, question the validity of a categorical “hands-off” approach, which deems excessive prices to be outside the realm of competition law. We consider separately the weight that should be assigned to each ground for non-intervention. Subsequently, we argue in favor of a case-by-case approach which explores the factual matrix of each case and considers the benefits, costs, and net effects of intervention.

A Ezrachi, 'Unchallenged Market Power? The Tale of Supermarkets, Private labels and Competition Law ' (2010) World Competition [...]

Recent decades have witnessed a distinct increase in the sales and popularity of private labels. The growing market share of private labels has transformed the landscape of retail competition in developed countries. Major retailers are no longer confined to their traditional roles of purchasers and distributors of branded goods. By selling their own label products within their outlet they compete with their upstream brand suppliers on sales and shelf space. This ‘vertical competition’ is not confined solely to ‘value’ categories of products. These days, retailers offer private label goods catering for the value, specialized and premium markets. These developments, and the increasing confidence that consumers have in private labels, have increased the bargaining position and market power of retailers as their labels compete directly with the leading manufacturers’ brand and its ‘value’ alternatives. This unique relationship and the increased role played by private labels raises fundamental questions as to their pro-, and possible anti-, competitive effects. It further highlights the shifting power balance between the producer and distributor and between the private label and branded good. This paper focuses on the effects of private labels, sold in major supermarkets, on retail competition and consumer welfare. In particular, it considers how supermarkets affect competition due to the fact that they retain control over shelving, in-store promotion and the pricing of branded and own label goods in addition to having superior access to consumer data. Furthermore, it reviews the enforcement of competition law in a private label environment and the difficulty in balancing the beneficial short-term effects of private labels and their possible, harmful, long-term effects. It subsequently questions whether these difficulties imply a lack of competitive harm or reflect a gap in regulation, as traditional analysis fails to encompass the increased market power of retailers and the existence of vertical competition.

A Ezrachi and J Thanassoulis, 'Upstream Horizontal Mergers and (the Absence of) Retail Price Effects' (2013) Journal of Competition Law and Economics (forthcoming) [...]

The paper explores the retail price effects of upstream and mid stream horizontal mergers. It questions the prevailing assumption in merger review according to which such transactions will have similar effects on retail price as that of downstream horizontal mergers. The analysis illustrates how a sophisticated profit-maximizing merged entity may find it more profitable to enter into efficient contracts which seek to maximise the profit of the distribution channel, and so ensure that retail prices are not raised. The merged entity uses its market power and improved bargaining position to extract as much of that profit as possible from the retailer. We therefore argue that one cannot simply assume a direct link between the creation of market power upstream following a merger transaction, and the subsequent increase in retail prices. An analysis of the effects of upstream mergers on retail prices should call for a more nuanced appraisal which distinguishes the transfer of wealth within the operators in the distribution chain from the possible price impacts on final consumers.

A Ezrachi and Maria Ioannidou, '‘Public Compensation’ in Competition Cases – A Complementary Mechanism to Damages Actions ' (2012) Jnl of Euro Competition Law & Practice [...]

EU competition law enforcement has undergone significant changes in the past decade, aimed at improving its effectiveness by employing more actors (national competition authorities and courts) and more ‘flexible’ procedures (commitments decisions and settlements). Occupying centre stage alongside these developments were efforts to advance private EU competition law enforcement and consumer involvement therein. Yet, while the number of damages actions in competition cases has steadily increased in some Member States, this increase has been modest and uneven across Europe. Procedural difficulties, excessive costs, risks and the multitude of legal systems involved, are only some of the obstacles still curtailing the availability of effective judicial redress in competition law cases. In addition, difficulties in launching group actions and adopting a harmonised Euro-wide collective redress mechanism, further limit access to corrective justice. This paper addresses shortcomings in the private enforcement of competition laws across Europe. It explores the possibility and desirability of deploying public enforcement to promote some of the objectives traditionally linked to damages actions in national courts. More specifically, it advocates in favour of including elements of compensation for injured parties, as part of the public enforcement of competition law (hereafter ‘Public Compensation’). Under the proposed mechanism, at the end of a public investigation, the competition authority would be able to impose not only a fine but also award a certain form of compensation to the injured parties, either individually identified or defined more broadly as the injured class. This mechanism provides an attractive vehicle for supplementing damage claims; narrowing the gaps in corrective justice, while fulfilling the traditional deterrent function of public enforcement. These benefits, we argue, justify consideration of a formal approach toward Public Compensation, which would facilitate its implementation across the European Union. Such mechanism could be implemented alongside possible future changes to the private enforcement landscape. This paper advances a two-fold argument addressing the questions of ‘why’ and ‘how’ Public Compensation is desirable. We begin by identifying the gap in the enforcement system that Public Compensation could fill, and offer further normative justifications for Public Compensation. We then consider the merit in advancing a more formal, fused approach toward competition law enforcement. Subsequently we move on to review cases in which the competition authority imposed or accepted compensation as part of the public inquiry. These cases provide inspiration for the ensuing proposal of a formal, institutional approach.
