Intertemporal Population Ethics: Critical-Level Utilitarian Principles
在人口规模、个体寿命、出生时间等变化的跨期模型中，通过“死者效用独立性”公理刻画了临界水平广义功利主义规则，并证明跨期福利主义环境下社会贴现被排除，适合关注人口伦理与社会评价的学者。
"This paper considers the problem of social evaluation in a model where population size, individual lifetime utilities, lengths of life, and birth dates vary across states. In an intertemporal framework, we investigate principles for social evaluation that allow history to matter to some extent. Using an axiom called independence of the utilities of the dead, we provide a characterization of critical-level generalized utilitarian rules. As a by-product of our analysis, we show that social discounting is ruled out in an intertemporal welfarist environment. A simple population-planning example is also discussed."
