AbstractWe study the problem of aggregating discounted utility preferences into a social discounted utility preference model. We use an axiom capturing a social responsibility of individuals’ attitudes to time, called consensus Pareto. We show that this axiom can provide consistent foundations for welfare judgments. Moreover, in conjunction with the standard axioms of anonymity and continuity, consensus Pareto can help adjudicate some fundamental issues related to the choice of the social discount rate: the society selects the rate through a generalized median voter scheme.

Ramsey Rule

The economic values of investing in long-term public projects are highly sensitive to the social discount rate (SDR). We surveyed over 200 experts to disentangle disagreement on the risk-free SDR into its component parts, including pure time preference, the wealth effect, and return to capital. We show that the majority of experts do not follow the simple Ramsey Rule, a widely used theoretical discounting framework, when recommending SDRs. Despite disagreement on discounting procedures and point values, we obtain a surprising degree of consensus among experts, with more than three-quarters finding the median risk-free SDR of 2 percent acceptable.

Climate Damages

The debate on the economics of climate change has focused primarily on the choice of the social discount rate, which plays a key role in determining the desirability of climate policies given the long-term impacts of climate damages. Discounted utilitarianism and the Ramsey Rule dominate the debate on discounting. The chapter examines the appropriateness of the utilitarian framework for evaluating public policies. More specifically, it focuses on the risky dimension of climate change, and on the failure of utilitarianism in expressing both concerns for the distribution of risks across the population and concerns for the occurrence of catastrophic outcomes. The chapter shows how a shift to the prioritarian paradigm is able to capture those types of concerns, and briefly sketches the main implications for the choice of the social discount rate.
