在本文中，我们推广了帕累托效率的概念，使其适用于环境中的内生种群。提出了两个效率的概念：-效率和-效率.这两个概念的不同之处在于它们如何对待未出生的潜在代理人。我们发现，这些概念是密切相关的帕累托效率的概念时，生育率是外生的。我们证明了Barro-Becker型生育率选择模型的第一福利定理的一个版本，并讨论了如何推广这一结果。最后，我们研究的例子中，生育率的决定是没有效率的均衡设置，我们把它们分为设置中出现的家庭内部和设置中出现的家庭之间的效率低下。
In this paper, we generalize the notion of Pareto efficiency to make it applicable to environments with endogenous populations. Two efficiency concepts are proposed: -efficiency and -efficiency. The two concepts differ in how they treat potential agents that are not born. We show that these concepts are closely related to the notion of Pareto efficiency when fertility is exogenous. We prove a version of the first welfare theorem for Barro-Becker type fertility choice models and discuss how this result can be generalized. Finally, we study examples of equilibrium settings in which fertility decisions are not efficient, and we classify them into settings where inefficiencies arise inside the family and settings where they arise across families.
