Information Spillovers in Experience Goods Competition
研究了体验品市场中，消费者试用产品后对类似产品的信息溢出如何影响企业定价和竞争利润，发现企业可能通过高价吸引知情消费者获利，即使产品在试用前难以区分。
Trialing an experience good allows consumers to learn their value for the sampled good and also informs beliefs about their value for similar products. These demand-side information spillovers across products create a relatively well-informed group of potential future consumers for rival firms. When both switching consumers and repeat buyers are profitable, firms face reduced incentives to set a low initial price to attract inexperienced consumers. Switchers and repeat buyers are more likely to be profitable in new product categories that build on major innovations and when firms can price discriminate based on purchasing history. We suggest that competing products and services arising from new innovations often have demand-side information spillovers from any product trial and are, hence, settings where competing firms can make overall profits even when selling products that consumers perceive to be indistinguishable prior to initial trial.
