The Nash counterfactual considers the question: what would happen were I to change my behaviour assuming no one else does. By contrast, the Kantian counterfactual considers the question: what would happen were everyone to deviate from some behaviour. We present a model that endogenizes the decision to engage in this type of Kantian reasoning. Autonomous agents using this moral framework receive psychic payoffs equivalent to the cooperate-cooperate payoff in Prisoner’s Dilemma regardless of the other player’s action. Moreover, if both interacting agents play Prisoner’s Dilemma using this moral framework, their material outcomes are a Pareto improvement over the Nash equilibrium.

普遍化与我们：内生博弈论道义论

纳什反事实考虑了一个问题：假设没有其他人这样做，我会改变我的行为会发生什么。相比之下，康德反事实考虑的问题是：如果每个人都偏离某些行为会发生什么。我们提出了一个模型，该模型将参与这种康德推理的决定内生化。使用这种道德框架的自主代理会收到相当于囚徒困境中合作-合作收益的心理收益，而不管其他玩家的行为如何。此外，如果两个相互作用的主体都使用这个道德框架来玩囚徒困境，那么他们的物质结果就是对纳什均衡的帕累托改进。
