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.
