Concepts and Milestones
• Some Important Concepts– (Explicit) Collusion: direct communication
among firms to coordinate their anticompetitive behavour (e.g. ??)
– Cartel: consortium of colluding firms– Tacit Collusion: indirect communication
among firms to coordinate their anticompetitive behavour
– Price leadership: common form for tacit collusion (largest firm leads, other follow)

Theory of Collusion
• Infinitely Repeated “Workhorse” Game– 2 firms – Inverse Demand: p=100-q1-q2– Identical Constant Marginal Cost: c=40– Marginal Revenue: MR = 100 – 2q– Cournot Outcome: qc=20 pc=60 πc=400– Monopoly Outcome: qm=30 pm=70 πm=900– Firm’s discount rate is (unknown) r– Can firms do better by colluding?

Theory of Collusion
• Challenges to Collusion: – Coordination and Bargaining
• How to enforce compliance? • price leadership, markup pricing, basic points• Different coordination targets
– Imperfect Monitoring• How to distinguish cheating from business cycle?
– Change in Market Demand– Supply Shocks and Technological Change– Barriers to Entry

A Practice of Collusion
• Joint Executive Committee (Porter, 1983)• Research questions:
– How to distinguish empirically between competitive and collusive regimes?
– How stable cartels are?• Approach:
– Explore time frame when cartels were legal– Use observed demand shocks to identify the
model
![Page 14: Collusion, Cartels, and Price Fixing Agreements · collusion (largest firm leads, other follow) Concepts and Milestones • Milestones – 1870s to 1890s: “golden era” of cartels](https://reader036.fdocuments.in/reader036/viewer/2022081613/5fb39ebfe7eb594b5712d394/html5/thumbnails/14.jpg)
A Practice of Collusion
• JEC: Railroad Cartel, 1880 – 1886• Market share allocation • Two cases of entry, but no cut-throating • Main competitor: water transportation• Demand rises in winter (lakes freeze)• Imperfect monitoring • Limited punishment, reversals allowed
![Page 15: Collusion, Cartels, and Price Fixing Agreements · collusion (largest firm leads, other follow) Concepts and Milestones • Milestones – 1870s to 1890s: “golden era” of cartels](https://reader036.fdocuments.in/reader036/viewer/2022081613/5fb39ebfe7eb594b5712d394/html5/thumbnails/15.jpg)
A Practice of Collusion
• Econometric Approach:– “Structural” approach, two equations– Railroad service demand Qd =f(Pd,Lakes)
• Lakes: 1 if Great Lakes are open to navigation– Railroad service supply Ps =g(Qs, S, I)
• S: 1 for structural cartel changes (e.g. entry)• I: 1 if cartel breaks (observed / unobserved)
– Market clearing conditions Qd= Qs, Pd= Ps
– Estimation strategy: 2SLS, ML

Application of Antitrust Laws
• Facilitating practices: The Ethyl Case• Market for anti-knock compounds• Factors helping collusion:
– Highly concentrated market (4 firms) – Roughly equal market shares – Relatively homogenous product – Absence of good substitutes
• Prices stayed stable, though demand dropped
![Page 20: Collusion, Cartels, and Price Fixing Agreements · collusion (largest firm leads, other follow) Concepts and Milestones • Milestones – 1870s to 1890s: “golden era” of cartels](https://reader036.fdocuments.in/reader036/viewer/2022081613/5fb39ebfe7eb594b5712d394/html5/thumbnails/20.jpg)
Application of Antitrust Laws
• Factors preventing collusion:– Prices were not transparent– Lumpy sales – High incentives to bargain for discounts – Product differentiation through transportation
costs • FTC sued industry under FTC Act
Section 5 (unfair competition)– Certain practices facilitate tacit collusion and
should be banned
![Page 21: Collusion, Cartels, and Price Fixing Agreements · collusion (largest firm leads, other follow) Concepts and Milestones • Milestones – 1870s to 1890s: “golden era” of cartels](https://reader036.fdocuments.in/reader036/viewer/2022081613/5fb39ebfe7eb594b5712d394/html5/thumbnails/21.jpg)
Application of Antitrust Laws
• FTC arguments:– Prices stayed high despite demand drop– Companies facilitated collusion by
• Giving advance notice to price changes• Posting price changes in press• Using uniform delivered pricing• Adopting “most-favoured-client” (MFC) clause
– Prices are “too similar” despite product variation
![Page 22: Collusion, Cartels, and Price Fixing Agreements · collusion (largest firm leads, other follow) Concepts and Milestones • Milestones – 1870s to 1890s: “golden era” of cartels](https://reader036.fdocuments.in/reader036/viewer/2022081613/5fb39ebfe7eb594b5712d394/html5/thumbnails/22.jpg)
Application of Antitrust Laws
• Industry defence:– Prices are not perfectly uniform– Substantial non-price competition– Press anouncements do not matter– Transportation costs are low– MFC clause wanted by clients– All facilitating practices were before
competition, so no intent to monopolize• FTC lost the case in the appeals court
