演講摘要 : A credence good is a product or service whose usefulness or necessity is better known to the seller than to the buyer. This information asymmetry often persists even after the credence good is consumed. The author proposes two new theories of expert cheating, suggesting that identifiable heterogeneities among customers can cause expert sellers to defraud their customers. According to these theories, cheating arises as a substitute for price discrimination, and experts cheat selectively. For instance, experts target high-valuation and high-cost customers. Finally, selective cheating may damage the communication of useful information from customers to experts and result in inferior services.
