Which of the following is a common policy tool used when markets fail to provide public goods?

• A. Rely exclusively on private charity.
• B. Do nothing and allow free riding.
• C. Deregister all industries.
• D. Government provision or financing of public goods and coordinating with markets.

Answer: (D)

When markets fail to provide public goods at an efficient level, a government-led approach is needed. Public goods are non-excludable and non-rivalrous, so individuals can benefit without paying, which gives rise to the free-rider problem and under-provision if left to markets alone. The common remedy is for the government to provide the good directly or to finance its production through taxation, often coordinating with markets to deliver the service efficiently. This ensures the good is available to everyone and at a level that reflects social benefit, rather than leaving it to voluntary contributions that may be insufficient. Private charity can’t reliably supply large-scale public goods, doing nothing perpetuates under-provision, and deregistering industries doesn’t address the core issue.
