Question

Quizplus · Accepted Answer

A public good is a good that is non-excludable and non-rival. National defense is non-excludable because everyone benefits from it regardless of whether or not they contribute to its provision, and it is non-rival because one person's consumption of national defense does not diminish the amount available to others. Apples and cars are both rival goods, meaning one person's consumption of them does diminish the amount available to others. Education is non-excludable but is rival because one person's consumption of education does use up resources that could have been used by others.
