Question

Quizplus · Accepted Answer

National parks are a public good because they are non-excludable (once the park is created, it is difficult to exclude anyone from using it) and non-rivalrous (one person using the park does not diminish its availability to others). License plates, commercial airlines, professional football games, and newspapers are not public goods as they are either excludable or rivalrous (or both).
