"Fly-by-Night" Firms and the Market for Product Reviews
研究了第三方信息提供如何影响信息不对称和声誉形成市场中的价格与供给，发现降低信息成本会提高优质企业利润、降低新企业价格并减少劣质企业。
This paper presents a model that permits third-party information provision in a market characterized by information asymmetries and reputation formation. The model is used to examine how the market for information provision affects prices and supply in the primary market. They find that decreasing the cost of providing and using information (1) increases, rather than decreases, the margins received by reputable service firms; (2) decreases the price of new, untested service firms (so reputation is more costly to build); and (3) leads to more high-quality firms and less " fly-by-night" firms.
