A pure public good is:

Question

BlackTom AI · Accepted Answer

A pure public good is nonrival in consumption and nonexcludable. Nonrival means one person’s consumption does not reduce the amount available for others (e.g., national defense or a public broadcast); nonexcludable means it is not feasible to prevent nonpayers from enjoying the good’s benefits (people cannot be excluded from national security or street lighting).

Relevant knowledge points:
- Rivalry: whether one person’s use diminishes another’s ability to use the good. Rival → private good (food); nonrival → public/club good.
- Excludability: whether providers can prevent nonpayers from using the good. Excludable → market can charge; nonexcludable → free-rider problem.
- A pure public good combines both nonrivalry and nonexcludability. This leads to market failure because private firms cannot easily charge users; government provision or collective financing is often needed.

Step-by-step reasoning:
1. Define pure public good = nonrival + nonexcludable.
2. Compare each option to that definition:
   - Option A: “one that is nonrival in consumption and whose benefits are not subject to exclusion” explicitly states both nonrival and nonexcludable, matching the definition.
   - Option B: “one that is nonrival in consumption” mentions only one property (nonrivalness) and omits nonexcludability, so incomplete.
   - Option C: “one whose benefits are not subject to exclusion” mentions only nonexcludability and omits nonrivalry, so incomplete.
   - Option D: “one that can easily be sold by the unit” describes a private, excludable, rival good—opposite of a public good.

Why the correct answer is correct:
Option A states both essential characteristics. Only when a good is both nonrival and nonexcludable does it qualify as a pure public good, producing classic free-rider problems and justifying collective provision.

Conclusion: The correct answer is “one that is nonrival in consumption and whose benefits are not subject to exclusion,” which matches the provided answer.
