    Study Notes

    Microeconomics: Externalities, Public Goods, and Common Resources

    • Market Failure: Occurs when free markets fail to allocate resources efficiently.
    • Causes of Market Failure: Externalities, public goods, market power, and asymmetric information.
    • Externality: The uncompensated impact of one person's actions on the well-being of a bystander.
      • Negative Externality: Causes harm (e.g., pollution, second-hand smoke from cigarettes, noise pollution from construction). Results in overproduction and lower prices than socially optimal.
      • Positive Externality: Provides benefits (e.g., education, vaccinations, research and development). Results in underproduction and lower prices than socially optimal.
    • Welfare Economics and Market Efficiency: Examines how resource allocation affects economic well-being. Market efficiency occurs when marginal benefit equals marginal cost. Externalities disrupt this balance.
    • Graph of Negative Externalities: Social cost includes both private cost and external cost. Socially optimal quantity is less than market equilibrium quantity.
    • Graph of Positive Externalities: Social benefit includes both private benefit and external benefit. Socially optimal quantity is greater than market equilibrium quantity.
    • Public Policies to Address Negative Externalities:
      • Command-and-Control Policies: Direct government regulation (e.g., emission limits).
      • Market-Based Policies:
        • Corrective (Pigovian) taxes: A tax equal to the external cost to internalize a negative externality (e.g., carbon tax).
        • Tradable pollution permits: Permits are issued, firms buy and sell in a market, encourages emission reduction.
    • Public Policies to Address Positive Externalities: Subsidies (financial support for activities with positive externalities; e.g., grants for education, tax breaks for R&D).
    • The Coase Theorem: If property rights are well-defined and transaction costs are low, resources will naturally gravitate to their highest-valued use, regardless of who owns the property rights. Potential private solutions to externalities.
    • Case Study: Climate Change and Carbon Taxes: Climate change as a global negative externality. A carbon tax internalizes the social cost of greenhouse gas emissions.
    • Objections to Pollution Taxes: Ethical and fairness concerns; potential disproportionate effects on low-income households; concerns over industrial competitiveness.
    • Public Goods and Common Resources: Types of goods that can lead to market failures.
      • Public Goods: Non-excludable and non-rival (e.g., national defense, public fireworks display, clean air).
      • Common Resources: Non-excludable but rival (e.g., oceans, fishing grounds, public lands).
    • Free-Rider Problem: Occurs when people receive benefits without paying (e.g., national defense). Solution: Government provision funded through taxes.
    • Tragedy of the Commons: Common resources are overused due to individual incentives. Example: Overfishing, overgrazing, traffic congestion. Solution: Government regulation, quotas, or creating property rights.
    • Specific examples:
      • Education: Higher productivity, lower crime rates, and informed voters are positive externalities of education.
      • Air pollution: Factories producing pollution that affects health, solutions consist of regulations, pollution permits, corrective taxes.
    • Challenges of the Coase Theorem: Low transaction costs, negotiation costs, high number of affected parties, and legal/enforcement difficulties can limit its feasibility.
    • Government solutions to the free-rider problem: Public provision of goods funded by taxes (e.g., national defense, public broadcasting).
    • Characteristics of Public Goods: Non-excludable and non-rival.
    • Common resource challenges : Overuse, example: overfishing in the ocean.
