Real-World Examples of Market Failure for AP Micro Students

📚 Quick Study Guide

• 🌍 Market Failure: Occurs when the allocation of goods and services by a free market is not Pareto optimal. In simpler terms, it means resources are not being used efficiently.
• ⚖️ Externalities: Costs or benefits incurred by a third party who did not choose to incur that cost or benefit. Can be positive (e.g., education) or negative (e.g., pollution).
• 🏛️ Public Goods: Non-excludable (everyone can access them) and non-rivalrous (one person's use doesn't diminish another's). Examples include national defense and street lighting.
• 🛡️ Asymmetric Information: One party in a transaction has more information than the other, leading to inefficient outcomes. Classic example: used car market.
• 💪 Market Power: When a single firm or a small number of firms can significantly influence market prices (e.g., monopolies).
• 📉 Inequality: Markets can sometimes lead to very uneven distributions of wealth and income, which society might deem undesirable.
• 💡 Government Intervention: Governments may intervene to correct market failures through regulations, taxes, subsidies, and direct provision of goods and services.
