在这项研究中,我们开发了一个模型的社会选择彩票,人们的心理特征是可变的,他们的喜好可能是不完整的,不完整或嘈杂的人际比较的幸福是可能的。形式上,我们假设个人偏好描述的冯诺依曼-摩根斯坦(vNM)的偏好顺序的空间彩票的心理物理状态;社会规划者必须构建一个vNM的偏好顺序彩票社会状态。首先,我们考虑一个模型,其中个人vNM偏好顺序是不完整的(因此不是所有的人际比较都是可能的)。然后,我们考虑一个模型,其中的个人vNM偏好顺序是完整的,但未知的规划,因此建模的随机变量。在这两种情况下,我们得到了一个功利主义的社会福利函数的特征。
In this study, we develop a model of social choice over lotteries, where people’s psychological characteristics are mutable, their preferences may be incomplete, and incomplete or noisy interpersonal comparisons of well-being are possible. Formally, we suppose individual preferences are described by a von Neumann-Morgenstern (vNM) preference order on a space of lotteries over psychophysical states; the social planner must construct a vNM preference order on lotteries over social states. First, we consider a model where the individual vNM preference order is incomplete (so not all interpersonal comparisons are possible). Then, we consider a model where the individual vNM preference order is complete, but unknown to the planner, and thus modelled by a random variable. In both cases, we obtain characterizations of a utilitarian social welfare function.
