Study Notes
Property Rights & Externalities
- Property rights involve the right to be compensated for externalities, internalizing them.
- The Coase Theorem relates property rights, efficiency, and externalities.
- When transaction costs are absent and trading externalities is possible, market mechanisms lead to efficient outcomes, regardless of initial allocations.
- Two reasons why markets for externalities may not exist:
- High cost
- Free rider effect
Negative Externalities
- Negative externalities lead to producing a greater quantity than socially desirable.
- Socially optimal quantity is lower than equilibrium quantity.
- Socially optimal price is higher than equilibrium price.
- Methods to reduce pollution externalities:
- Taxes (e.g., carbon tax, Pigouvian tax)
- Regulating quantity (cap-and-trade, bans, location restrictions)
- Inducing markets for pollution (property rights)
- Voluntary agreements
Pollution Externalities
- Pollution externalities have intergenerational and international dimensions.
- Taxes are more effective than quantity limits in punishing polluters. Quantity limits are less popular than taxes overall.
Positive Externalities
- Positive externalities cause markets to produce less than socially desirable.
- Socially optimal quantity is greater than equilibrium quantity.
- Socially optimal price is lower than equilibrium price.
- Addressing these involves methods like subsidies to encourage the positive externality-generating service.
Issues with Carbon Taxes
- Carbon taxes are frequently politically unpopular.
- Carbon taxes are often regressive, disproportionately affecting low-income individuals.
- Carbon taxes only address carbon emissions, not other greenhouse gases like methane.
