A public good is one that a person can use without reducing the use of it for another person. One of the best example of a public good is national defense. One person can benefit form. our national defense without reducing another person's benefits. In fact, it is difficult to keep any person in our society from enjoying the benefits of national defense.
The market system does not work well in producing public goods. This is because a person who refuses to pay for a public good cannot be kept from using it. Suppose that the neighbors in a high crime area decide to hire a police force. Each neighbor, except Mrs. Smith, agrees to pay $100 a year for it. Mrs. Smith refuses to pay because she knows that if all the others pay the $100, the police will guard the area anyway. So Mrs. Smith can enjoy the services of the police force without paying $100.
The market system has no way to deal with this type of problem. For this reason, we cannot ask each person to make a direct payment in the form. of product price. Therefore, we collect money for public goods by using taxes.
