Question

Quizplus · Accepted Answer

A good is rival if its use by one person decreases the quantity available for someone else. This means that if one person consumes or uses the good, there is less of it left for others to consume. Examples of rival goods include food, clothing, and cars. Non-rival goods, on the other hand, can be used by multiple people simultaneously without reducing the amount available to others, such as digital downloads or streetlights.
