1. Additional Causes of Market Failure
More emphasis on government policy tools:
Indirect taxation (used to reduce negative externalities by increasing cost).
Subsidies (to promote positive externalities).
Government regulations (laws and restrictions to guide market behavior).
Government advertising (awareness campaigns to influence demand).
Comparison of Public & Private Goods:
Public goods: Non-rivalrous & non-excludable (e.g., defense, street lights).
Private goods: Rivalrous & excludable (e.g., a Mars bar).
2. Further Breakdown of Externalities
Negative Externalities (Overallocation)
Additional Government Responses:
Tax incentives for firms to reduce harmful production (e.g., tax breaks for clean energy).
Bans or restrictions (e.g., cigarette smoking bans in public spaces).
More emphasis on "internalizing" costs – ensuring that producers include external costs in their pricing.
Positive Externalities (Underallocation)
Additional Government Responses:
"No Jab, No Play" policy – regulation to ensure children receive vaccinations.
Tax incentives for R&D – encouraging firms to engage in research.
3. Asymmetric Information & Government Policy
Further examples of how asymmetric information leads to market failure:
Sellers having more information (e.g., second-hand car sales, misleading advertising).
Buyers having more information (e.g., health insurance – those who purchase insurance may know they have a pre-existing condition).
Government Responses:
Consumer Protection Laws (Australian Consumer Law – Section 18 bans misleading advertising).
Mandatory disclosure (requiring companies to provide key product details).
Consumer education (advertising campaigns to inform buyers).
4. Common Access Resources & Intertemporal Efficiency
More focus on the link between common access goods and sustainable development:
Overuse leads to depletion → future generations suffer.
"Tragedy of the Commons": When individuals act in self-interest, shared resources get overexploited.
Additional Government Responses:
Carbon tax (making polluters pay for emissions).
Fishing/hunting limits (to prevent depletion).
Bans on harmful chemicals (e.g., CFC bans to protect the ozone layer).
5. Government Failure (Unintended Consequences)
Definition Expansion:
Occurs when government intervention worsens efficiency rather than improving it.
Key cause: Policy solutions often create secondary problems.
More Case Studies of Government Failure:
Jakarta’s "Jockey" Problem:
High-occupancy lanes to reduce congestion led to poor individuals becoming "passenger jockeys" for hire.
Instead of reducing congestion, it created a new black market for car passengers.
Fuel Tax Credit Scheme:
Intended to support businesses, but led to inefficient fossil fuel use and higher emissions.
Tariffs & Protectionism:
Protect local jobs but reduce efficiency by keeping inefficient industries alive.
Unfair Dismissal Laws & Moral Hazard:
Protects workers from job loss but may reduce employee effort.
Illustration of Government Price Interventions:
Price Ceilings (Maximum Prices):
Example: Prescription drugs.
Unintended consequence: Shortages & black markets.
Price Floors (Minimum Prices):
Example: Minimum wage.
Unintended consequence: Higher unemployment.
