In A Treatise of Human Nature, Hume argues that morality pertains primarily to character, and that actions have moral content only to the extent that they signal good or bad character. I formalize his signalling theory of moral/immoral actions using simple game-theoretic models. Conditions exist under which there is a separating equilibrium in which actions do indeed credibly signal character, but conditions also exist in which there is only a pooling or semi-separating equilibrium. A tradeoff is identified between the signalling value of actions, and the consequentialist goal of incentivizing all character types to choose beneficial actions.

性格特征：休谟道德与不道德行为理论的信号模型

在人性论休谟认为，道德主要与品格有关，行为只有在表明品格好坏时才具有道德内容。我使用简单的博弈论模型形式化了他的道德/不道德行为信号理论。在存在分离平衡的条件下，行动确实可靠地表明了特征，但也存在仅存在汇集或半分离平衡的条件。在行动的信号价值和激励所有角色类型选择有益行动的结果主义目标之间进行权衡。
