Strategic Decisions in Oligopolies: Famous Industry Examples

📚 Quick Study Guide

• 🤝 An oligopoly is a market structure with a small number of firms, none of which can keep the others from having significant influence.
• ⚖️ Key strategic decisions in oligopolies involve pricing, output, advertising, and research & development.
• 🎲 Game theory is often used to model the strategic interactions between firms in an oligopoly. Key concepts include Nash equilibrium and the Prisoner's Dilemma.
• 🎯 Examples of strategic decisions include price leadership (one firm sets the price, and others follow), collusion (firms cooperate to set prices or output), and non-price competition (e.g., advertising, product differentiation).
• 📈 Market concentration is typically high in oligopolies, often measured by the Herfindahl-Hirschman Index (HHI).
• 📜 Antitrust laws aim to prevent anti-competitive behavior in oligopolies, such as price-fixing and market allocation.
