A Note on Quality Disclosure and Competition
研究了产品差异化程度如何影响双寡头企业披露质量信息的动机，发现披露成本高低决定了差异化是促进还是抑制信息披露。
Abstract Competitive pressure is lower in markets where goods are more differentiated. I analyze how a change in the degree of horizontal product differentiation affects the incentives of duopolists to disclose quality information. If disclosure is costly, then a firm discloses high qualities but conceals low qualities in equilibrium. The higher the disclosure cost, the higher the equilibrium threshold below which firms conceal quality information. I show that the effect of product differentiation on quality disclosure depends on the cost of disclosure. For low (high) disclosure costs, a firm discloses more (respectively, less) quality information if goods become more differentiated.
