Question

Quizplus · Accepted Answer

Public goods are available to all without direct payment and are non-excludable, meaning it is impossible to prevent anyone from using them. Examples of public goods include streetlights, public parks, and national defense. Private goods are the opposite of public goods, as they are excludable and one must pay to use them. Common goods are rivalrous but non-excludable, such as fish in the ocean. Toll goods are excludable but non-rival, such as a toll road where one must pay to use it but it doesn't necessarily get more crowded if more people use it.
