Delegated Expertise, Authority, and Communication
研究了决策者依赖专家获取信息时，委托决策与沟通建议两种方式的优劣，发现当沟通能使专家获取对双方同等有用的信息时，沟通优于委托。
A decision maker needs to reach a decision and relies on an expert to acquire information. Ideal actions of expert and decision maker are partially aligned and the expert chooses what to learn about each. The decision maker can either get advice from the expert or delegate decision making to him. Under delegation, the expert learns his privately optimal action and chooses it. Under communication, advice based on such information is discounted, resulting in losses from strategic communication. We characterize the communication problems that make the expert acquire information of equal use to expert and decision maker. In these problems, communication outperforms delegation.
