标题： Private Experimentation, Data Truncation, and Verifiable Disclosure

摘要： 发送者通过一系列私人实验获得证据以说服接收者。发送者在选择实验时完全灵活，这取决于私人的实验历史。 发送者可以可信地披露每个实验的结果，但不能证明他是否披露了一切。 通过要求“持续披露”，我首先表明私人顺序实验问题可以重新表述为一个静态问题，在这个问题中，发送者选择一个单一信号来了解状态。 利用这一观察，我推导出均衡中被选信号的必要条件，然后识别这些信号所诱导的一组信念。 最后，我从受限于该集合的价值函数的凹化中刻画出发送者最优信号。 显示英文摘要

摘要： A sender seeks to persuade a receiver by presenting evidence obtained through a sequence of private experiments. The sender has complete flexibility in his choice of experiments, contingent on the private experimentation history. The sender can disclose each experiment outcome credibly, but cannot prove whether he has disclosed everything. By requiring `continuous disclosure', I first show that the private sequential experimentation problem can be reformulated into a static one, in which the sender chooses a single signal to learn about the state. Using this observation, I derive necessary conditions for a signal to be chosen in equilibrium, and then identify the set of beliefs induced by such signals. Finally, I characterize sender-optimal signals from the concavification of his value function constrained to this set.
