4th Winter School on Economics of Competition Law

Objective of the Winter School
Markets are becoming increasingly global and the approaches to regulate them more economics based. Modern competition law differs from traditional competition law in that it now reflects the dominance of the economic model of analysing the market structures and behaviour. Competition Economics assumes importance as regulatory and competition authorities have moved to adopt more economics based approaches in analysing business practices and determining anticompetitive behaviour. The aim of the winter school was to familiarize participants with economic literature in the field of competition law and equip them with globally applied economic principles and techniques. It was intended for the benefit of competition lawyers, academicians, professionals, economic or law consultancies and students. With this objective in mind, a four-day Winter School on ‘Economics of Competition Law’ was organised by CIRC and Economics Partners during 12th to 15th December 2018 at India Habitat Centre, New Delhi, India. See Annexure l for information on organizers.

Structure and Pedagogy
The winter school was spread over four days and the topics covered included basic economic concepts, introduction to oligopoly and game theory, econometrics, economics of horizontal agreements, exclusionary behavior and vertical agreements, defining market through relevant economic tools, market power, case study analysis, economics of networks and platform markets, merger analysis, antitrust damages and interface between IPR and Competition Law. Detailed agenda with information on sessions is provided in Annexure II.

Participants were provided with a training kit and a reference list of related books and journal articles by each faculty. Participants were given all the presentations and lecture material in pen drives. Provision was also made for facilitating participants’ regular feedback on the conduct of the sessions. At the end of the training, participants were awarded certificates for the successful completion of the course. All the training sessions began with introduction of the concept at hand to facilitate clarity among the participants on competition law cases.

Lectures were interactive that stimulated interest among the participants and fostered interesting question and answers. The idea was to promote strategic understanding and in depth analysis of the topics that were discussed. Presentations, graphical representations, discussions, and information exchange happened during the sessions with examples from decided and hypothetical case studies. Faculty was supportive and answered the queries and questions during the sessions. Further, the sessions were planned to give adequate time to discuss the basic, advanced and applied aspects of the economics. The breaks after sessions were allocated to give all the participants as well as the faculty time for more informal discussions.

The faculty consisted of following experts from the field:

1) Derek Ritzmann, Director, Economics Partners
2) Saattvic Saattvic, Senior Consultant, Economics Partners
3) Payal Malik, Economic Advisor, CCI

Day 1: December 12, 2018

SESSION 1: Regulating Markets through Competition Law and Policy – Derek Ritzmann
Dr. Derek Ritzmann engaged the first session of the four-day-long winter school on economics of competition law. He started with a basic introduction to the competition policy, the consequences of lack of competition, and the advantages of competition in a general market. Considering the majority of participants belonged to law background, he first familiarized the students with the general economic concepts like definition of economic welfare, monopoly, oligopoly, market model, etc. He then marked a line of difference between ‘competition policies’ and ‘regulations’ followed by a discussion on the various sources of market failure. The participants were taught about the evolution and approaches of different economic schools of thoughts on competition Law principles.

As an overview, the first session introduced the candidates to the basic idea of a market and the role of competition law and policies in regulating that market.

SESSION 2: Introduction to Basic Economic Concepts and Role of Economics – Saattvic Saattvic
The second session was delivered by Mr. Saattvic on the topic Introduction to Basic Economic Concepts and Role of Economics. He bagan by defining a market model and then explaining how to prepare a market model and what its essentials elements are. He explained the concepts of demand and supply with the help of demand curve and supply curve, as what leads to creation of these curves and what would be the effects of a change in price or quantity over these curves. He also explained the reason behind the movements and shifts in the curves and the difference between them. He concluded the session by explaining the concept of ‘Welfare and Total Welfare’. The second session introduced the candidates to the important concepts of economics which were necessary to build an understanding for the upcoming sessions.

SESSION 3: Market Structures & Competition Law and Policy Introduction to Oligopoly and Game Theory – Derek Ritzmann
The third lecture for the day was delivered by Dr Derek Ritzmann, he explained the definition and characteristics of the various types of markets like Monopoly, Oligopoly, Perfect competition and Differentiated Product Markets. Then, with the help of graphs, he explained the difference between the points of equilibriums in a monopoly and a perfectly competitive market and the reasons for the differences. He explained the concept of market power in relation to a perfectly competitive market and monopoly. He further explained a few concepts from a game theory like prisoners’ dilemma, Nash equilibrium, etc. with the help of real-life examples and how they are outcomes of the existence of market power in the market. He also explained how these theories apply differently to different types of markets.

SESSION 4: Introduction to Econometrics – Yugank Goyal
The last session of the first day was delivered by Dr. Yugank Goyal, who taught the basic concepts of econometrics and regression to the participants. He gave an example of Pollution and factors affecting the level of it in a given area and how one can use regression and econometrics in finding the interrelation between various factors. He explained how various factors are dependent on some independent factor and how this relationship is used to arrive at various outcomes. The participants were sensitized about the use of econometrics in competition law cases and intricacies involved. He further explained how economists use these techniques in finding the relationship between demand, supply, increase and decrease in price, with various factors, and to do the competition assessment.

DAY 2: December 13, 2018

SESSION 5: Economics of horizontal agreements: Cartels and other Coordinated Effects – Saattvic Saattvic
In the first session on day 2, the participants were taught about the economics involved in coordinated effects and horizontal agreements. Mr Saattvic started this session by demarcating the difference between the legal definition of cartels and the economic definition of collusion. He discussed finite and infinite games that firms would play in a given market. The economic theories like game theory, prisoner’s dilemma and Stigler’s conditions for collusion to exist were discussed. He further discussed legal and illegal collisions and how to detect collision with the help of economic evidence and relevance of the same in the prosecution of cartels. He discussed the concepts of price level analysis, price parallelism, parallelism plus, price wars and econometrics used in detecting cartels. He concluded the session by discussing the importance and usage of economics in ex-ante and ex-post policies against collusion, designing auctions appropriately to deter collusion, identifying industries susceptible to collusion, identifying appropriate levels of fines & estimating cartel damage. He also discussed the leniency regime and economic justifications for colluding in this session.

SESSION 6: Exclusionary Behaviour and Vertical Agreements – Derek Ritzmann
In this session, Dr Ritzmann covered the antitrust issues concerning the resale price maintenance (RPM), exclusive dealing agreements, exclusive supply agreements; price reference agreements and MFNs; and possible pro-competitive justifications. He began with explaining the object and effects-based approach used across jurisdictions in detecting the anti-competitive activities concerning the vertical agreements. He discussed whether resale price maintenance and exclusive dealing are inherently anti-competitive. With the help of case laws like Sylvania case and concepts like the error-cost framework, Dr Ritzmann explained the intricacies of anti-competitive analysis of vertical agreements. He further discussed the concepts of inter and intra brand competitions and explained one profit monopoly theorem and theory of harm. He concluded this session by discussing the free rider problem and its possible solutions.

SESSION 7: Delineating Relevant Market and Measurement of Market Power – Derek Ritzmann
“Market definition is one of the most important analytical tools for the competition authorities to examine and to evaluate competition concerns”

He taught about the Herfindahl Hirschman Index analysis and role of market power in competitive assessment of proposed mergers. Dr Rtitzmann then moved on to the Price Pressure Tests/Upward Pricing Pressure Test (UPP) as a direct measure of competitive effects as HHI is an insufficient tool. He discussed other Merger simulation models involving more complex econometrics which CCI might employ in their merger analysis in future.

DAY 4: December 15, 2018

SESSION 13: Economics of Platform Markets – Payal Malik
The first session of the last day was engaged by Ms Payal Malik (Advisor – Competition Commission of India). She started the session by giving the background of markets with networks effects enumerating its features and market structure. Through several examples and case discussions, Ms Malik described in detail the aspects of cross-externality and inefficiency of perfect competition, a feature that leads to profit inequality between firms in platform markets. Ms Malik also introduced to the participants the idea of Schumpeterian race of market dominance that suggests that monopolies are only the end outcome of fierce competition that takes place between firms for the market. Participants were also sensitized about the key challenges like big data, surge pricing, algorithm collusion etc. that are faced by an antitrust authority in the digital economy.

SESSION 14: Intellectual Property Rights and Anti-Competitive Practices – Derek Ritzmann
The second session of the fourth day was conducted by Dr Derek Ritzmann. He taught the participants about the concept of Standard Essential Patents (SEP) and discussed anti-competitive issues associated with SEPs. He started the lecture by first establishing the commonalities between IP law and competition law followed by enumerating the concept of technological standards, Standard Setting Organizations (SSO), SEPs, associated hold-up problem, and licensing at FRAND rate. While discussing the FRAND rates, Dr. Ritzmann talked about the Georgia Specific Factors in the U.S. to decide the reasonable licensing rate and modifications in the factors that were adopted after Microsoft v. Motorola case. The session was ended with a brief discussion of exceptional circumstances in which ‘compulsory licensing’ can be issued.

SESSION 15: Interface between IP, Innovation and Competition Law – Payal Malik
In this session, participants were sensitized about linkages between IP law, Competition law and also about their importance in building the innovation ecosystem of a country. Ms Malik described the problem associated with a market structure where some degree of allocative inefficiency (P>MC) is evident to get the rate of return for risky R&D investment. This creates a tension between antitrust and IP protection. Detailed discussion was also held on licensing of IP, when and why do firms license, competition assessment of licensing arrangements, how to analyze licensing terms, what is the anti-competitive harm and pro-competitive benefits, and lastly on antitrust challenges in online platforms.

SESSION 16: Panel discussion on Economics of common ownership and competition law/ Economic analysis of innovative/high technology mergers

Two-panel discussions were held at the end of the Winter School.
Moderator: Saattvic Saattvic, Senior Consultant, Economic Partners
Payal Malik, Advisor – Competition Commission of India
Dr Derek Ritzmann, Director – Economics Partners
G. R. Bhatia, Partner and Head of the Competition Law Practice Group, L&L Partners

Topic I: Economics of common ownership and competition law
The panellists discussed anti-competitive implications of common ownership by investment funds in multiple competing companies in the same industry. The discussion began by laying out the foundation of the growth of common ownership by investment funds and gradually proceeded to discuss the anticompetitive implications of it. Key questions that panellist pondered upon are: Whether or not intervention and what kind of intervention or remedied these antitrust authorities provide? Are the remedies at counter-purposes to the objectives of the stability of the financial market? What are the channels of institutional investor’s influence?

Topic II: Economic analysis of innovative/high technology mergers
The panel discussion started with the question of how the possession of a large amount of data on consumers leads to competitive harm. It was discussed that ownership and control over the data are being considered as powerful as far as dominance is concerned. There was also a debate about the public good nature of data that changes the analysis of dominance. It was held that regarding mergers and acquisition, there is a statutory lacuna because there is no valuation of the data. Unstructured data that has not been worked upon is not considered so valuable as per the current regulation that leads to undervaluation of the acquired firm.

Valedictory Session & Certificate Distribution
Ms.Payal Malik, Economic Advisor of CCI and member of Governing Council of CIRC, Ms Nidhi Maheshwari, and the lead mentors- Dr.Derek Ritzmann, Director- Economics Partners and Saattvic, Senior Consultant- Economics Partners were present for the valedictory session and certificate distribution to the participants.

Ms Garima Sodhi delivered a vote of thanks to the participants on behalf of CIRC and to Economics Partners for collaborating and successfully leading the lectures in Winter School. It was followed by a vote of thanks from Economics Partners to the participants for their active participation and interaction during the Winter School. Certificates of participation to all the participants were issued jointly by CIRC and Economics Partners to all the participants.
