Tiebout模型的一类变形及其理论诠释

以往文献中的Tiebout模型假设不考虑对就业机会的限制,所有人都靠股息来维持生活,即社区居民收入具有同质性,但此假设的限制性过强而不具有现实性。在该模型的基础上,放松这条假设,将其改为社区居民收入具有异质性,在此条件下研究地方公共产品的供给问题,建立了一个Tiebout的改进模型,并与原模型进行了比较,得出了社区达到均衡的条件以及达到均衡后社区的结构特征上有别于Tiebout原模型的结论。

Several Changed Tiebout Models and Theoretical Interpretation

Tiebout models in former financial theory literatures were conducted on inherent presupposition,without taking into account the restriction on employment,and the income of the community residents was,therefore,of homogeneity and originated from dividend only. In view of its limiting nature of the homogeneity,a reformed Tiebout model was set up to study the supply of the local public products. A comparison between the two models showed that the reformed one was closer to the reality with fewer restrictive prepositions. Conclusions were drawn on the terms for community equilibrium and the community structure features after equilibrium,which proved to be different from that of the original Tiebout model.
