Intergenerational Population Ethics

Abstract

This paper characterizes a novel class of welfare criteria for settings with endogenous population. The core innovation is to treat parents’ fertility preferences as ethically relevant, deferring to them on the quality--quantity trade-off under conditions of equality. The resulting family of criteria generalizes discounted utilitarianism by reconciling respect for parents' fertility preferences with equity across generations. These criteria resolve long-standing normative dilemmas that afflict existing approaches to population ethics, such as total and average utilitarianism. After formal characterization, I illustrate the criterion in stylized examples and a Barro–Becker environment.
