The Equilibrium in the Model of Individual Consumption of Goods with Group Payment

In some cases, people’s payment for consuming a commodity is determined regardless of their individual consumption, just based on the total cost and a constant policy. This paper is to study the general consumer behavior based on the macroeconomic views, and analyze the subject based on microeconomics. Given that a part of consumer payment is paid by other individuals in the group, the consumers’ individual or social viewpoint determines their consuming policy: a viewpoint based on which people consider their consuming behavior independent of the others’ point or see it as joint with the others. By analyzing the subject matter by using the game theory and the mathematical proof of the subject, we proved that there was Nash equilibrium in consumer behavior of this type of consumers. Public goods are a special group of this kind of consumption, in which payers are all the community members who indirectly pay for public goods, and the consumers are all people
