Page 2: Oligopoly Overview
Definition: A market structure characterized by a small number of firms.
Price and Marginal Revenue: In oligopolies, price (P) is greater than marginal revenue (MR); indicates potential for deadweight loss.
Entry Barriers: Difficult entry may lead to long-run profits being positive.
Government Role: Government intervention may be necessary to manage markets.
Modeling Difficulty: Complex due to need to model firm rivalry.
Page 3: Modeling Rivalry in Oligopoly
Key Questions:
How do firms respond to rivals?
How do firms anticipate rival responses?
Can firms limit future competition to increase profits?
How should government consider rivalry to improve efficiency?
Page 4: Sample Questions
What prompts price increases from competitors (e.g., Coke and Pepsi)?
How does one firm predict competitor production (e.g., Toyota vs. Honda)?
What strategies prevent competition from copying a successful product?
Page 5: Strategic Settings
Definition: Strategic settings occur when a firm's profits are affected by other firms' actions.
Understanding Competition: Needs insights into behavior in such settings.
Game Theory: The discipline focused on strategic thinking.
Page 6: Game Theory Foundation
Origins: Developed in the 1940s-1950s, initially for military strategy.
Applications: Relevant in various fields like business and parenting.
Purpose: To help firms predict rivals’ actions and their own decision impacts.
Page 7: Cooperation vs Competition
Outcomes for firms:
Potential to eliminate competition for high profits.
Engage in competition with varying profit outcomes.
Page 8: Cooperation
Monopoly Pricing: Firms can achieve higher profits by coordinating pricing to monopoly levels.
Profit Sharing: Successful cooperation can lead to shared monopoly profits.
Page 9: Competition Dynamics
If firms agree to cooperate, an incentive exists for individual firms to undercut prices to capture a larger market share.
Page 10: Cooperation vs Competition Outcome
Industry Profit Maximization: Requires cooperation among firms.
Individual Firm Profits: Maximized through competition with rivals.
Page 11: Analyzing Strengths
Examine the dominant force between cooperation and competition through the Prisoner’s Dilemma framework.
Page 12: Prisoner’s Dilemma Matrix
A game structure showing outcomes based on decisions made by two parties (e.g., Tchaikovsky and Conductor) with varying consequences for each choice.
Page 13: Conductor's Dilemma
Better to confess regardless of Tchaikovsky's actions. Likely outcome: Both confess, serving a 10-year sentence instead of 3 years had they refused.
Page 14: Implications for Firms
Firms face a similar dilemma where cooperative benefits exist, yet individual incentives lead to price cutting.
Page 15: Case Study - Home Depot and Lowe’s
Market Dynamics: Analyzing pricing strategies under cooperative conditions.
Demand equation: P = 1000 - Q. Each firm's cost structure assumed to be manageable.
Page 16: Monopoly Outcome
Result: Solving yields quantity Q = 500 bulbs at price P = $5.00 when cooperating results in equal distribution of profits.
Page 17: Cheating Implications
Example of one firm underpricing, capturing market share, resulting in increased profitability but harming cooperative relations.
Page 18: Chain Reaction of Competition
Price drops to $2, resulting in each firm’s revenue being lower than monopoly outcomes, indicating self-destructive competition.
Page 19: Possible Outcomes Table
Analyzing outcomes based on collaborative or competitive approaches, directing revenue consequences.
Page 20: Conclusions on Expected Outcomes
It appears beneficial for firms to engage competitively, though it results in lower aggregate profit than what could be achieved cooperatively.
Page 21: Oligopoly Structure
Recognizing differences: Firms in an oligopoly interact repeatedly unlike one-shot players in Prisoner's Dilemma.
Page 22: Key to Cooperation

Page 27: Outcomes of Cheating vs Retaliation

Page 28: Factors Affecting Collaboration
Monitoring: Fewer firms enhance oversight; need for predictable demand diminishes cheating opportunities.
Discounting Future: How firms assess the importance of future earnings impacts cooperation viability.
Page 29: Monitoring Ease
Fewer dominant firms simplify monitoring, especially in stable demand environments; complexity complicates cheating detection.
Page 30: Future Valuation

Page 31: Summary of Conditions for Collusion
Easier in established markets with fewer firms employing linear pricing amid predictable demand fluctuations.
Page 32: Essential Cooperative Measures

Page 36: Quality Considerations
Firm competition based on perceived quality impacts collaboration incentives. Low-quality products hinder commitment.
Page 37: Summary of Collusion Dynamics
Effective collusion is dependent on market stability, firm count, homogeneity, and demand predictability.
Page 38: Enhancing Collusion Potential
Strategies include maintaining excess capacity, minimizing firm quantity through mergers, and price-matching commitments.
Page 39: Internet's Effects on Collusion
Transparency: Easier price comparisons benefit consumers; however, monitoring competitors also aids firms in colluding.
