Simple Bounds on the Value of a Reputation
用熵技术研究长期玩家面对一系列短期玩家的经典声誉模型，推导出长期玩家均衡收益的显式上下界。
We introduce entropy techniques to study the classical reputation model in which a long-run player faces a series of short-run players. The long-run player's actions are possibly imperfectly observed. We derive explicit lower and upper bounds on the equilibrium payoffs to the long-run player.
