The Social Discount Rate Andrew Caplin and John Leahy∗ January 2004 Abstract What discount rate should be applied to social investments? It is standard to use the market interest rate, thereby respecting private preferences. We show that application of this “revealed preference” criterion rests on faith, not logic. This paper surveys theories and practices in the choice of the social discount rate for cost–benefit analysis of public projects. Choosing an appropriate rate is also highlighted by recent debates on the economics of climate change. The fact that private discount rates are likely to exceed the social rate of discount would tend to imply that the level of investment would be lower if a private discount rate is used instead of a social discount rate. A simple example suffices to illustrate the point. Suppose in year 0 an investment project could be undertaken for a cost of 100. associated rates apply. We distinguish between a social-welfare-equivalent discount rate appropriate for determining whether a given policy would augment social welfare (according to a postulated social welfare function) and a finance-equivalent discount rate suitable for determining whether the policy would offer a potential Pareto improvement. 1 .
