Question

Quizplus · Accepted Answer

Nontoll roads can be considered public goods when they are not congested because they are non-excludable and non-rivalrous. However, when they become congested, they can act more like common resources because they become rivalrous, meaning one person's use diminishes another's ability to use it effectively.
