A public good is defined as, “a good that is available for everyone to consume, regardless of who pays and who doesn’t, a good that is nonrival in consumption and nonexcludable”. With this type of good it is unpractical to keep the people that did not pay for the good from enjoying it the same way as those who had paid. Some examples of public good’s are, public defense, streetlights, police service, children play parks, and the fireworks. Most of these services are supported by taxes, but if someone does pay their taxes they still can benefit from the services that others are paying for. The people that do not pay for these types or goods or services are called free riders.
