Commission —Recoupment test – considers whether the dominant undertaking has a reasonable prospect of recouping its losses (required under the US Case law in order to prove the abuse of predatory pricing) Profit maximization —The goal of the company is to maximize its profit — — — — — — —Profit is maximize when: MC (marginal costs) = MR (marginal revenues = the increase in revenue from selling one more unit of a product) Øadditional costs of producing one extra unit of output are still covered by the additional revenue earned by this extra unit of output Øthis rule hold goods for companies with market power as well as without market power http://www.onefourfour.co.uk/images/profit1.jpg Economies of scale —The cost advantages that a business obtains due to expansion →increasing capacity lead to economies of scale (the higher capacity reduces the average costs) —Economies of scale, especially when they are substantial, are important explanation for concentration tendencies in market —May result from: —Indivisibility of certain production factors —The bigger truck that transport is more while still requiring only one driver —Technical-physical relationship —The bigger oil tanker than requires relatively less steel to be built —Economies of increased dimensions —Larger company that may obtain discounts when buying larger amounts of inputs Economies of scale —Static internal economies of scale —not related to past production —important economies of scale – in motor vehicles or other mean of transport sector, chemicals, paper and printing,… —Dynamic internal economies of scale —a lowering of cost production over time as a result of experience obtained on past cumulative output (“learning effect”) http://www.investujeme.sk/cs/images/resize/little-pig-380.jpg Contestability —Contestable market —there are no sunk costs or other entry barriers and consumers are willing to switch quickly, before incumbents can react, to the better offer of new entrants —The potential competition exists →“hit and run” entry is possible —it disciplines the incumbents, even when they have very high market shares —In practice not many markets are truly contestable —entry usually requires sunk costs, incumbents are often in a position to react quickly, that is before consumer loyalty wears down — Economic and empirical analysis (tests) used in investigation of competition law infringement —Analysis of Price elasticity of Demand —Price elasticity of a product = how demand for that product changes with change of price of the product —Market definition —SSNIP test („the test of Small but Significant and Non-transitory Increase in Price „) – arises from price elasticity of demand —Merger simulation – the technique to simulate the impact of mergers in specific markets —Information on demand + assumption about the nature of competition in the market Economics and EC Competition law and policy —Increasing role of economics in antitrust proceedings →Importance of economic analysis —Economics helps in evaluating effects and designing structured rules —Economics help in understanding market dynamics and building evidence — http://c.photoshelter.com/img-get/I0000kqLmEEnwOIQ/s Investigation effects of using economics —Spell out a logically consistent theory of consumer harm —Validate that theory empirically —Check the realism of the underlying assumptions (ex-ante validation) —Check whether observed market outcomes are consistent with the predictions of the theory (ex-post validation) —Identify alternative pro-competitive motivations for the practice —Use of established theory, extensions, ad hoc developments —Develop testable hypothesis —(The role of Economics in European Competition Enforcement and Policy - Damien Neven, Chief Economist DG COMP, European Commission) The Chief Competition Economist —A part of the Commission's Competition Directorate General since 2003, and assists in evaluating the economic impact of its actions —Functions: —Support function – the CCE gives economic guidance and methodological assistance —Checks and balance function - the CCE provides the Commissioner with an independent opinion —The CCE cooperate with academic world: —The Economic Advisory Group on Competition Policy (“EAGCP”) —a group of approximately 20 leading academics working in the area of industrial organization with a keen interest on Competition policy —Two types of activities: —Opinion on important policy issues —Annual forum →he objective is to discuss policy issues and economic methodology in the context of particular cases. —The Economic Seminar Series on competition policy (“ESS”) More economic approach to art. 82 (102 TFEU) —The objective of Article 82 is the protection of competition on the market as a means of enhancing consumer welfare and ensuring an efficient allocation of resources…. First, it is competition, and not competitors, that is to be protected. Second, ultimately the aim is to avoid consumers harm. — Competition Commissioner Neelie Kroes speech 2005 —An economics-based approach requires a careful examination of how competition works in each particular market in order to evaluate how specific company strategies affect consumer welfare… By focusing on the effects of company actions rather than on the form that these actions may take, an economics-based approach makes it more difficult for companies to circumvent competition policy constraints by way of attempting to achieve the same end results through the use of different commercial practices. — Report by the EAGCP – An economic approach to Article 82 — — More Economic Approach —Why? —The aim is to achieve the maximum benefit for consumers from EC competition rules —The strict legislatic enforcement of the competition rules in the past raised serious difficulties —There was a need to investigate complex cases, which require in-depth fact-finding and rigorous economic and/or econometric analysis. — More Economic Approach —February 2009 - new legislation which implements the revised approach: Guidance on the Commission's enforcement priorities in applying Article 82 of the EC Treaty to abusive exclusionary conduct by dominant undertakings —The guidance paper sets out an economic and effects-based approach to exclusionary conduct under EC antitrust law (rather than form-based approach) —Rule of reason rather than per se rule — Effect-based approach v. Form-based approach —Effect-based —Form-based —Commission would carefully discern competition on the merits, which has beneficial effects for consumers and should therefore be promoted, from competition that is liable to lead to anticompetitive foreclosure. —Since the focus of the Commission's policy is on the effects on consumers, it should be prepared to examine claims put forward by a dominant firm that its conduct is justified on efficiency grounds. — —The form of behavior is important for identifying of anticompetitive conduct. —The risk that statutory provisions unduly thwart pro-competitive strategies. — Rule of reason v. per se rule —Rule of reason —Per se —It is necessary to prove adverse market effects (conduct may be defended on the ground that adverse effects are outweighed by beneficial ones) —+ authorities distinguish anticompetitive behavior from procompetitive — - difficult evidence, legal uncertainty, decision making is unpredictable —The presumption of anticompetitive effect of certain conduct. —No tools of economic analysis —+ Predictability, legal certainty, easier evidence —- Inappropriate state intervention (regulation can distort competition) —
