非线性定价的福利再分配效应研究——基于非对称双寡头市场的分析

A Study of Welfare Redistribution Effect of Nonlinear Pricing:Based on An Analysis of the Asymmetric Duopoly Market

较之"线性定价","非线性定价"在社会福利方面的优势被现有理论反复证明。在肯定"非线性定价"方式能够改进社会总福利的同时,指出并不是每一个市场主体的福利水平都能够通过"非线性定价"方式得到改进。通过建立模型、计算和比较分析,提出了在上述两种情况下,"非线性定价"可能会对特定的市场主体产生"福利剥夺",从而出现福利再分配效应。

Compared with linear pricing, the advantages of nonlinear pricing in the area of social welfare have been proved repeatedly in the existing theory. While confirming that the nonlinear pricing can improve the social welfare, this paper points out that not all market entities can get a welfare improvement through nonlinear pricing. By establishing models to calculate and analyzes, we propose that ＂welfare deprivation＂ may be found in some specific market entities by the nonlinear pricing in the above mentioned two different kinds of situations, which may lead to the welfare redistribution effect.
