Question

Quizplus · Accepted Answer

A local police department is a public good because it is non-excludable and non-rivalrous. It is non-excludable because once the police department is funded and established, everyone within its jurisdiction can benefit from its services, regardless of whether they contribute financially. It is non-rivalrous because the consumption of police protection by one person does not diminish the amount of protection available for others.

A toll road is a private good because it is excludable and rivalrous. Only those who pay the toll can use it, and the use of the road by one person reduces the amount of road available for others.

Conrail and a rent-a-cop agency are both private goods as they provide services to specific individuals or organizations who pay for their services.
