Private and social discount rate
The US government uses a variety of discount rates but something around 7% is what the US Office of Management and Budget (OMB) recommends for a pretax rate of return on private investments. In the United Kingdom, HM Treasury fixes the social discount rate for the public sector at 3.5%. Calculation Private & Social Discount Rates. SOCIAL Risk Free Cost of Capital = the rate of return that is earned when there is absolutely no risk of earning more or less than the expected return. SOCIAL Risk Premium = amount required to compensate capital owners for potential differences between expected and actual returns. Social Discount Rate in Theory There is a body of theoretical literature on the choice of SDR. Theory maintains that, if there was a single capital market that was perfectly competitive, there will be one interest rate that prevails, and this one interest rate would equate marginal time preference of savers with the marginal productivity of capital. Problems arise when aggregating individual Ramsey discount rate functions into a social discount rate function that would serve as a basis for an SDR. Using the opportunity cost of capital would be better described as a method of obtaining an SDR than as a rationale for discounting. The Social Discount Rate Andrew Caplin and John Leahy∗ January 2004 Abstract What discount rate should be applied to social investments?

social discount rate would be around 3.5-4 percent. To the extent that the region improves on its past performance, which admittedly has been quite dismal and therefore may bias the results, the social discount rate to be used in the evaluation of future projects would increase. In this regard, estimates in the 5-6 percent would be more appropriate.
