为避免每个牧民只考虑自身的利益,而不顾及完全利己行为对他人带来的影响,致使公共草地过度放牧,最终导致每个牧民都得不偿失的“公地悲剧”现象,将Marco和Morgan的轻微利他博弈均衡理念植入公地悲剧模型之中进行研究。结果表明:如果每个牧民均表现出轻微利他的有限理性行为,则每个牧民都受益;当牧民轻微利他的程度不一致时,利他程度弱些的牧民比利他程度强些的牧民相对利润高。
為避免每箇牧民隻攷慮自身的利益,而不顧及完全利己行為對他人帶來的影響,緻使公共草地過度放牧,最終導緻每箇牧民都得不償失的“公地悲劇”現象,將Marco和Morgan的輕微利他博弈均衡理唸植入公地悲劇模型之中進行研究。結果錶明:如果每箇牧民均錶現齣輕微利他的有限理性行為,則每箇牧民都受益;噹牧民輕微利他的程度不一緻時,利他程度弱些的牧民比利他程度彊些的牧民相對利潤高。

In order to overcome the tragedy of the commons in public resource management, i.e. when each herder only considers his own interests regardless of the impact on others, it results in overgrazing of the public grassland, and eventually brings more loss than gain to each herder, this paper brings in the concept of slightly altruistic equilibrium raised by Marco and Morgan. It is found that if all herders show slight altruism with bounded rationality, the results are good for each herder, and that herders with weaker degree of slight altruism have higher profits than those with stronger degree.
