摘要: 本文在策略型利他博弈中假定参与人是利他的,基于此假设,引入具有偏好映射的利他博弈与利他广义博弈,并证明博弈模型中利他均衡的存在性定理。作为应用,我们在规范型博弈和不同广义博弈中给出利他均衡存在性结论。

关键词: 利他博弈, 利他均衡, 偏好映射, 外部性偏好

Abstract: In this paper, we assume that the players are altruistic in strategy-form games. Following the idea, we introduce the altruistic games and altruistic generalized games with preference correspondences, and prove the existence theorems of altruistic equilibria. As applications, we obtain the existence theorems of altruistic equilibria for normal-form games and generalized games.

Key words: altruistic game, altruistic equilibria, preference correspondence, external preference
