论公共品个人需求曲线的加总

On the Aggregation of Personal Demand Curve of Public Goods

传统的公共品需求理论并没有特别考虑公共品个人需求曲线的加总。事实上,公共品需求曲线的加总与私人品个人需求曲线的加总不同,并且要复杂得多。在充分考虑公共品的性质后,可以运用萨缪尔森方法、中间投票者个人需求函数替代法以及社会效用函数法来加总公共品个人需求曲线。

The traditional public goods demand theory does not specifically take the aggregation of personal demand curve into consideration. Actually, the aggregation of public goods personal demand curve is different from that of private goods and even more complicated. After enough thinking of the nature of public goods, it is possible to apply Samuelson＇ s method, Substitution method of middle voter personal demand function together with social effectiveness function to aggregate public goods personal demand curve.
