Quality Disclosure and Product Selection*
研究了当新进入者需要零售商接纳时，高质量进入者会提前披露质量信息，而中等质量者可能选择不披露；强制披露虽只让高质量者进入，但可能损害消费者福利。
If entry requires accommodation by retailers, an incumbent manufacturer may transfer profits to retailers to maintain his dominant position. We show that such an incentive to transfer will induce a high‐quality entrant to disclose quality information prior to entry. Interestingly, retailers will accommodate not only a high‐quality entrant but also an intermediate‐quality entrant who chooses not to disclose. If disclosure is mandatory, however, only a high‐quality entrant can enter the market. Therefore, mandatory disclosure may be excessive in terms of consumer welfare.
