Question

Quizplus · Accepted Answer

National defense is a classic example of a public good because it is non-excludable, meaning no person can be excluded from its benefits, and non-rivalrous, meaning one person's consumption of national defense does not diminish the benefits available to others. Libraries may also be considered a public good because they are non-excludable and can be used by multiple individuals without reducing the benefits available to others, but they are not necessarily a universal example, as some libraries may charge fees or restrict access to certain patrons. Timber and natural gas are both private goods, as they are both rivalrous and excludable.
