Crime, Intimidation, and Whistleblowing: A Theory of Inference from Unverifiable Reports
研究委托人如何利用举报人的不可验证信息来干预代理人行为，发现过度依赖信息会堵塞举报渠道，因此政策设计必须对信息进行模糊处理。
Abstract We consider a game between a principal, an agent, and a monitor in which the principal would like to rely on messages by the monitor (the potential whistleblower) to target intervention against a misbehaving agent. The difficulty is that the agent can credibly threaten to retaliate against the monitor in the event of an intervention. In this setting, intervention policies that are responsive to the monitor’s message provide informative signals to the agent, which can be used to target threats efficiently. Principals that are too responsive to information shut down communication channels. Successful intervention policies must therefore garble the information provided by monitors and cannot be fully responsive. We show that policy evaluation on the basis of non-verifiable whistleblower messages is feasible under arbitrary incomplete information provided policy design takes into account that messages are endogenous.
