Public Goods and Free Rider Problem in Education

Steps:

• Identify market failure: Education has positive externalities, benefiting society beyond individuals.
• Recognize public good traits: Non-excludable (hard to prevent non-payers from benefiting) and non-rival (one person's education doesn't reduce others').
• Explain underprovision: In free markets, individuals underinvest due to free riders not contributing to full costs.
• Conclude government role: Subsidizing or providing free education ensures optimal consumption.

Why C is correct:

• Education qualifies as a public good with positive externalities, leading to free riders who benefit without paying, causing underconsumption in markets.

Why the others are wrong:

• A: Full awareness would increase demand but doesn't address externalities or free riders requiring government intervention.
• B: Education is underconsumed, not overconsumed, in free markets due to external benefits.
• D: Private benefits often exceed costs for individuals, but social benefits are higher, justifying subsidies.

Final answer: C
