Question

Quizplus · Accepted Answer

A public good is a good or service that is both non-excludable (meaning it is available to all members of society) and non-rivalrous (meaning consumption by one person does not diminish the availability of the good to others). Public goods are typically provided by the government, as private firms have little incentive to produce them due to the difficulty in charging individuals for their use. Examples of public goods include national defense, clean air and water, and public parks.
