Question

Quizplus · Accepted Answer

National defense is the best example of a public good because it is non-excludable (everyone benefits from it, regardless of whether or not they pay for it) and non-rivalrous (one person's use of national defense does not diminish another person's ability to use it). Legal services are not typically non-excludable or non-rivalrous, as those who cannot afford a lawyer may be excluded from receiving legal services and the use of a lawyer's time is rivalrous. A municipal library is non-excludable (people can enter and benefit from using books), but it is rivalrous (limited copies of books). Cable television programming is neither non-excludable nor non-rivalrous, as cable companies can exclude those who do not pay for their services and the use of cable programming is rivalrous.
