The market for public goods such as city parks are often subject to market failure . Private markets tend to undersupply these goods and services because of the free rider problem. One solution to this problem is for government to use people’s tax dollars to provide for public goods.
A public good is a good that consumers cannot be excluded from consuming and it is also non-rivalrous. For example, everyone has access to a city park.
A private good is a good that consumers can be excluded from consuming and it is also a rivalled good. For example, a private good is a pair of jeans. You would have to pay for the jeans and once you buy the jeans another person cannot buy the jeans.
