论溢价机制与消费者福利

A Theory of Premium System and Consumer Welfare

均衡价格一质量模型为建立信誉企业的溢价机制提供了基本的理论框架。但其赖以建立的信誉形成理论是以最简单的信誉调节模式为立论基础,在实际应用中尚有疏漏。本文以此为依据,补充了两种信誉调节的情形,并由此部分修正了受其影响的均衡p(q)模型,从理论上说明了信息技术改善及最低质量标准改变时的消费者福利状况。

Equilibrium price——quality schedule provides a basic framework for the construction of the premium system of reputation firms. While the underlying theory of reputabrion formation is based on the reputation adjustment mode, there exist some careless omissions in practice. This paper presents two brand-new reputation adjustment conditions and partially modifies p (q) model. It gives consumer welfare status in theory in terms of the improvement of information and the change of minimum quality standards.
