VCE Economics — Unit 3 AOS 1
Market Failure — Flashcards & Quiz
Market failure occurs when free markets fail to allocate resources efficiently, and it is the bridge between microeconomic theory and policy in VCE Economics Unit 3 AOS 1. You need to identify the four main types — public goods, externalities, asymmetric information, common access resources — and explain how each leads to under- or over-provision. The follow-up question is always about the intervention: taxes, subsidies, regulation, public provision, tradeable permits. Always evaluate intervention against efficiency, equity and unintended consequences.
Sample Flashcards
Q1: What is market failure? Identify the main sources.
Market failure occurs when the free market fails to allocate resources efficiently, resulting in a misallocation of resources and a loss of social welfare. Main sources: externalities (positive and negative), public goods, asymmetric information, market power (monopoly), and common resources.
Q2: Explain negative externalities and how they lead to market failure.
A negative externality occurs when production or consumption imposes costs on third parties. The social cost exceeds the private cost (MSC > MPC). The market overproduces because the external cost is not reflected in the price, creating allocative inefficiency.
Q3: Explain positive externalities and how they lead to market failure.
A positive externality occurs when production or consumption creates benefits for third parties. The social benefit exceeds the private benefit (MSB > MPB). The market underproduces because the external benefit is not captured in the price.
Q4: What are public goods? Why does the free market fail to provide them?
Public goods are non-excludable (people cannot be prevented from using them) and non-rivalrous (one person's use does not reduce availability). The free market fails because of the free-rider problem — consumers benefit without paying, so no firm can profitably supply the good.
Sample Quiz Questions
Q1: Market failure occurs when the free market achieves allocative efficiency.
Answer: FALSE
Market failure occurs when the free market FAILS to achieve allocative efficiency.
Q2: A negative externality causes the market to overproduce a good relative to the socially optimal level.
Answer: TRUE
The market ignores the external cost, producing more than the socially optimal quantity.
Q3: Positive externalities cause the market to overproduce a good.
Answer: FALSE
Positive externalities cause UNDERPRODUCTION, as the external benefit is not captured in the price.
