讲座题目：Strategic Sampling from Manipulable Data
讲座摘要：We consider a game played by a decision maker （she） and a data manipulator （he）. The decision maker samples data sequentially to learn a binary state, either high or low, and decides when to stop and take an action to match the state. The data manipulator can manipulate the data that the decision maker samples from and prefers the high action independent of the state. Both sampling and manipulating are costly. We characterize the unique Markov perfect equilibrium. In equilibrium, the data manipulator alternates between fully manipulating the data until the decision maker stops sampling and not manipulating at all. The decision maker consistently performs worse compared to a scenario without manipulation, while the manipulator does not necessarily benefit from the manipulation. Additionally, under manipulation, the decision maker may prefer static sampling to sequential sampling, in sharp contrast to the superiority of sequential sampling in the absence of manipulation.
