Learning Objectives
- Analyze externalities and market failure
- Understand government intervention: taxes, subsidies, price controls
- Evaluate regulatory approaches to natural monopolies
- Week 4-5: Market structures and pricing
- Understanding of efficiency concepts
1. Externalities
Negative Externality: Third party bears cost (pollution). Market overproduces. Positive Externality: Third party receives benefit (education). Market underproduces.
Solution: Pigouvian tax (negative) or subsidy (positive) to internalize externality.
2. Public Goods
Non-rival and non-excludable. Free rider problem leads to underprovision.
3. Price Controls
Price Ceiling: Maximum price (rent control). Creates shortages. Price Floor: Minimum price (minimum wage, agricultural support). Creates surpluses.
4. Regulating Monopoly
Natural Monopoly: Decreasing ATC over relevant range (utilities). Regulation Options: Marginal cost pricing (requires subsidy), Average cost pricing (zero profit), Rate-of-return regulation.
| Policy | Effect on Market | Example |
|---|---|---|
| Price Ceiling | Shortage | Rent control |
| Price Floor | Surplus | Minimum wage |
| Pigouvian Tax | Reduces negative externality | Carbon tax |
| Subsidy | Increases positive externality | Education grants |
Q1: Why do negative externalities lead to overproduction?Firms don't bear the full social cost, so private MC < social MC. They produce where private MC = MB, which exceeds socially optimal quantity. Q2: What is the free rider problem?With public goods, individuals can benefit without paying, leading to underprovision by the market. Q3: How does a price ceiling create a shortage?If maximum price is below equilibrium, Qd > Qs. Not all buyers can find the product.
