产品质量内部性问题的政府管制

Product Quality Internalities and Government Regulation

文章引入了对产品质量的分析,将产品质量和数量作为并列的因素进行考察,着重分析了产品质量的内部性问题,并进一步提出了单纯的较大的交易成本和单纯的不对称信息,都不能解释产品质量内部性问题产生的根源,与信息不对称紧密联系的较大的交易成本才是其根源。如何降低这种交易成本就成为政府对产品质量内部性进行管制,提高消费者福利水平的管制重点。

This paper introduces the analysis of product quality, taking product quality and quantity as the parallel analytical economic factors. Then the paper focuses on the Internalities of product quality, advancing that the pure information asymmetry and the pure high transaction costs cannot explain the source of the Intemalities of product quality. Asymmetric information should be closely linked with the high transaction costs, which is its fundamental reason. How to reduce the transaction costs is the key to regulating Product Quality Internalities and improving the level of consumer welfare.
