预期理论下一个纠正消费外部性的新视角

A New Perspective of Correcting Consumption Externality under Expectation Theory

消费外部性的存在,不论是正外部性还是负外部性,其结果都使资源达不到帕累托最优状态,导致整个国民收入减少,从而整个社会福利也相应的减少。借助预期理论,设计一种解决消费外部性的理论机制,可以进一步细化消费外部性中正负外部纠正机制,并可以为纠正消费外部性措施的发展提供一个新的理论视角。

The existence of consumption externality, either positive or negative, causes that resources cannot reach Pareto optimal state and that the whole national revenue reduces, correspondingly, the whole social welfare decreases. By means of expectation theory, we can design a theory to solve consumption externality, further refine positive and negative external eorreetion meehanism of eonsumption externality, and provide a new perspective for developing a correcting consumption externality.
