that people prefer consumption today to future consumption, and that invested capital is productive and provides greater consumption in the future. Properly applied, discounting can tell us how much future benefits and costs are worth today. Social discounting, the type of discounting discussed in this chapter, is discounting from Discounting Formula primarily converts the future cash flows to present value by using the discounting factor. Discounting is a vital concept as it helps in comparing various projects, and alternatives that conflict while making decisions since the timeline for those projects could be different. The welfare of future generations barely influences the outcome of such a rule when constant socially efficient discount rates are used for all time. The deleterious effects of exponential discounting ensure that projects that benefit generations in the far distant future at the cost of those in the present are less likely to be seen as efficient, even if the benefits are substantial in future value terms. The concept of discounting is central to economics, since it allows effects occurring at different future times to be compared by con-verting each future dollar into a common currency of equivalent presentdollars.Becauseof thiscentrality,thechoiceofanappropriate discount rate is one of the most critical issues in economics. It is an Economic theory predicts that reduced life expectancy should increase discounting of the future, yet empirical evidence on this point has been scarce, to date. 20 Some of our findings are consistent with this prediction including the increase in impatience with age, and the decrease in impatience for individuals with bequest motives and thus, effectively, a longer time horizon. Some of the other findings are less consistent, specifically the lack of a significant relationship between time Behavioral economists refer to this psychological quirk as hyperbolic discounting. Hyperbolic Discounting and Decisions Put simply, we “discount” things that will happen far in the future as being less important than those things occurring right now. Calculations for discounting are straightforward: for each year (n) in the future the value of costs or benefits is multiplied by (1/(1 + D) n) where D is the discount rate . Higher discount rates or longer delays produce lower net present value. A constant discount rate produces values that decline exponentially with time.
