Evidence Games: Truth and Commitment
研究了知情代理人向不知情委托人披露可验证证据的博弈,比较了事后奖励与事前承诺奖励两种机制,发现特定条件下两者结果相同。
An evidence game is a strategic disclosure game in which an informed agent who has some pieces of verifiable evidence decides which ones to disclose to an uninformed principal who chooses a reward. The agent, regardless of his information, prefers the reward to be as high as possible. We compare the setup in which the principal chooses the reward after the evidence is disclosed to the mechanism-design setup where he can commit in advance to a reward policy, and show that under natural conditions related to the evidence structure and the inherent prominence of truth, the two setups yield the same outcome.
