题目:        专家市场中的有效责任设计

Title       Efficient Liability in Expert Markets

主讲人:     张锦

Presenter:  Jin Zhang

摘要 (Abstract)

文章研究了专家市场中有效责任的设计。给客户提供专业服务的专家有可能产生逆向选择行为(提供“错误”的服务)或者道德风险问题(专家努力不足)。我们在文章中讨论在某些责任安排下,当价格加成足够接近时,专家会根据已有信息提供有效的服务。并且在有效的责任设计下,专家会投入最优的努力水平。但是,价格设计必须满足最低要求,否则在最大化消费者福利的目标函数下有效结果会被破坏。

We study the design of efficient liability in expert markets. An expert, who can provide treatments for a consumer's problem, may misbehave in two ways: prescribing the "wrong" treatment or failing to exert proper effort to diagnose the problem. We show that under a range of liabilities, the expert will choose the efficient treatment based on his information if the price margins are close enough. Furthermore, a well-designed liability rule can motivate the expert to also exert diagnosis effort efficiently. However, efficiency may be undermined if payments to the expert are set to maximize consumer surplus without certain minimum-price constraint.
