Which of the following is an example of a public good?

Question

Quizplus · Accepted Answer

A public good is something that is non-excludable and non-rivalrous, meaning it is available to everyone and its consumption by one person does not reduce its availability to others. A lighthouse is a classic example of a public good because its light is non-excludable and non-rivalrous - it is available to all ships in the vicinity, and one ship's use of the light does not reduce its availability to others. The other choices may be important services, but they are not public goods because they are either excludable (the cookies) or rivalrous (the subway).
