Does moral play equilibrate?
研究了部分道德动机的玩家在有限对称两人博弈中是否存在对称纳什均衡，分析了完全信息和不完全信息下的均衡存在条件，并用例子说明。
Abstract Some finite and symmetric two-player games have no (pure or mixed) symmetric Nash equilibrium when played by partly morally motivated players.The reason is that the “right thing to do” may be not to randomize. We analyze this issue both under complete information between equally moral players and under incomplete information between players of arbitrary degrees of morality. We provide necessary and sufficient conditions for the existence of equilibrium and illustrate the results with examples and counter examples.
