Quizplus · Accepted Answer

A highly demanded piece of computer software is not an impure public good because it is a private good, meaning it can be consumed only by those who pay for it and cannot be shared freely among individuals. A fairly congested interstate highway, a crowded swimming pool, and a movie theatre nearing capacity are impure public goods because they can be used by multiple individuals without reducing the availability or quality for others. However, they are impure because they have some characteristics of private goods, such as congestion or the ability to exclude non-payers in some situations.
