Project Description
Summary:
View help for Summary
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.

Because our survey aimed at disentangling the determits of the long-term Social Discount Rate, we restricted our sample to scholars who have been involved with these complex issues. For the purposes of this paper, an individual is deemed to be a potential 'expert' if he or she is a (co-)author of at least one pertinent publication in the field of (social) discounting in a leading economics journal. A publication is deemed to be 'pertinent' if it was published between January 2000 and March 2014 and, according to the Google Scholar engine, included at least one of the terms 'social discounting', 'social discount rate' or 'social discount factor'. We correct for scholars with multiple publications, and discarding papers that did not pass a weak relevancy test.
