摘要
运用极小极大后悔原则的思想研究了不完全信息下的封闭投标机制,给出唯一的极小极大后悔投标策略.在此基础上,研究了其效率问题,分别给出了存在事后有效、相对事后有效和事后无效的极小极大后悔投标策略的充要条件;探讨了它与Bayesian-Nash平衡点集间的关系,从效率的角度将它们作了比较,发现在多数情形下。
In this paper, we study sealed bid mechanism with incomplete information by means of minmax regret rule. A unique minmax regret bid strategy is given, and its efficiency is analysed. Finally, efficiency of minmax regret bid strategy is compared with Bayesian Nash equilibrium's.We find that in many cases Beyesian Nash equilibrum is prefered to minmax Regret bid strategy.
