An ordinal solution to King Solomon’s dilemma
研究了当部分人知道合法所有者而其他人不知道时，如何通过两阶段信息传递机制解决所有权争议，该机制仅依赖偏好的序数性质就能实现真实披露。
This paper examines mechanisms that can resolve ownership disputes when some agents know who the legitimate owner is, but others do not. The mechanism proposed is called “Solomonic” because it resolves the biblical dispute facing King Solomon over the true mother of a baby. It involves two stages of messages (claims) and yields truthful revelation using only ordinal restrictions on preferences.
