Goods can be classified in one of four different categories: private, common resources, quasi-public goods, and public goods, based on whether the good is rival and excludable in the range of demand. In a competitive market, the supply curve represents the marginal private cost of producing a good for the firm (labeled MPC) and the demand curve represents the marginal private benefit to the consumer of consuming the good (labeled MPB).
