Why Don’t People Trust Experts?
研究了信任品市场中专家与消费者之间的利益冲突,通过扩展模型解释了在消费者不了解专家成本函数时,均衡状态下普遍存在的消费者被不当对待现象。
Credence goods such as health care, legal and financial services, and auto repair create a conflict of interest by requiring experts to diagnose and provide services to uninformed consumers. Mistreatment of consumers appears widespread empirically, but a simple explanation for mistreatment under realistic assumptions has proved elusive. I generalize Uwe Dulleck and Rudolf Kerschbamer’s credence-good model to incorporate the highly realistic assumption that consumers do not observe experts’ cost functions. The model guarantees equilibrium mistreatment in a wide range of price-setting and market environments. The model also yields testable implications regarding the nature of mistreating firms and the direction of mistreatment.
