The full effects of decisions made today about many environmental policies -including climate change and nuclear waste- will not be felt for many years. For issues with long-term ramifications, analysts often employ discount rates to compare present and future costs and benefits. This is reasonable, and discounting has become a procedure that raises few objections. But are the methods appropriate for measuring costs and benefits for decisions that will have impacts 20 to 30 years from now the right ones to employ for a future that lies 200 to 300 years in the future? This landmark book argues that methods reasonable for measuring gains and losses for a generation into the future may not be appropriate when applied to a longer span of time. Paul Portney and John Weyant have assembled some of the world's foremost economists to reconsider the purpose, ethical implications, and application of discounting in light of recent research and current policy concerns. These experts note reasons why conventional calculations involved in discounting are undermined when considering costs and benefits in the distant future, including uncertainty about the values and preferences of future generations, and uncertainties about available technologies. Rather than simply disassemble current methodologies, the contributors examine innovations that will make discounting a more compelling tool for policy choices that influence the distant future. They discuss the combination of a high shout-term with a low long-term diescount rate, explore discounting according to more than one set of anticipated preferences for the future, and outline alternatives involving simultaneous consideration of valuation, discounting and political acceptability.

In this thesis, Orlando Zaddach applies a discounting scheme derived by Krysiak (2010) in the latest DICE model and presents its implications for optimal climate policy. Furthermore, he carries out a one-factor-at-a-time (OFAT) sensitivity analysis to check the discounting scheme for robustness. It turns out that the proposed discounting scheme fails in incorporating consumer sovereignty and intergenerational equity sufficiently.

Abstract: The social discount rate measures the rate at which a society would be willing to trade present for future consumption. As such it is one of the most critical inputs needed for cost-benefit analysis. This paper presents estimates of the social discount rates for nine Latin American countries. It is argued that if the recent track record in terms of growth in the region is indicative of future performance, estimates of the social discount rate would be in the 3-4 percent range. However, to the extent that the region improves on its past performance, the social discount rate to be used in the evaluation of projects would increase to the 5-7 percent range. The paper also argues that if the social planner gives a similar chance to the low and high growth scenario, the discount rate should be dependent on the horizon of the project, declining from 4.4 percent for a 25-year horizon to less than 4 percent for a 100-year horizon.
