Some Refinements of Nash Equilibria of Large Games
为大博弈引入了完美均衡、适当均衡和持久均衡的概念，证明每个大博弈至少存在一个完美均衡和适当均衡，并给出一个持久均衡可能不存在的例子。
The notions of perfect, proper, and persistent equilibria for large games are introduced. It is shown that every large game has at least one perfect and proper equilibrium. An example is given to show that a persistent equilibrium may fail to exist in a game. Journal of Economic Literature Classification Number: C79.
