AP Microeconomics Quiz: Incentive to Cheat on Collusion

📚 Quick Study Guide

• 🤝 Collusion: Occurs when firms in an oligopoly agree to limit competition, often by setting prices or output levels.
• ⚖️ Incentive to Cheat: Each firm has an incentive to increase its own output above the agreed-upon level because it can increase its profits if the other firms stick to the agreement.
• 📈 Individual vs. Collective Benefit: While collusion is beneficial for the firms collectively, it is not an equilibrium because each firm has an incentive to deviate.
• 💰 Profit Maximization: Firms maximize profit where marginal revenue (MR) equals marginal cost (MC). If a firm believes it can increase output without significantly affecting the market price, it will do so.
• 📉 Market Share: Cheating firms aim to increase their market share at the expense of other firms in the collusive agreement.
• 📝 Game Theory: Collusion scenarios can be analyzed using game theory, specifically the Prisoner's Dilemma, which illustrates the difficulty of maintaining cooperation even when it is in both parties' best interest.
• 🔍 Detection and Punishment: The success of collusion depends on the ability of firms to detect and punish cheating. Without effective enforcement, collusion is likely to break down.
