When does a firm disclose product information?
研究企业如何选择价格和产品信息披露策略，给出了完全披露成为唯一均衡结果的充要条件，适用于不同质量产品和水平匹配异质性。
A firm chooses a price and the product information it discloses to a consumer whose tastes are privately known. We provide a necessary and sufficient condition on the match function for full disclosure to be the unique equilibrium outcome whatever the costs and prior beliefs about product and consumer types. It allows for products with different qualities as well as some horizontal match heterogeneity. With independently distributed product and consumer types, full disclosure is always an equilibrium and a necessary and sufficient equilibrium condition is that all firm types earn at least the full‐disclosure profit.
