Answer:
D) the good is typically oversupplied in a market where the free-rider problem occurs?
Explanation:
The free rider problem refers to people using a good or a service and not paying for it, or not paying their fair share.
For example, students going to school in a different district than their family home. A grandmother decides to send her grandchildren to a school in her district, but they actually live in another district with schools that are not very good. The children should go to the school located in their own district since their parents pay taxes there, but since the grandmother lives in a better school district, they sign up as living with her.
The problem with free riding is that a good or service is used by too many people and paid by only a few, there is an oversupply of the good or service. But it is too difficult or too expensive to separate those who actually pay form those who don't. For example, police officers must "serve and protect" everyone, not just the people that pay their taxes. The same applies to the use of public beaches or parks, anyone can use them even without paying for their maintenance.
