Sequential Preference Revelation in Incomplete Information Settings
研究了在策略证明且非霸道的分配规则下，序贯偏好揭示如何导致代理人有意不诚实，并提供了保证均衡结果与诚实结果福利等价的条件。
Strategy-proof allocation rules incentivize truthfulness in simultaneous move games, but real world mechanisms sometimes elicit preferences sequentially. Surprisingly, even when the underlying rule is strategy-proof and nonbossy, sequential elicitation can yield equilibria where agents have a strict incentive to be untruthful. This occurs only under incomplete information, when an agent anticipates that truthful reporting would signal false private information about others’ preferences. We provide conditions ruling out this phenomenon, guaranteeing all equilibrium outcomes to be welfare-equivalent to truthful ones.
