Why is the use of discount rate in cost-benefit analysis (CBA)? May 19, 2013 / in FAQ - Economic Terms for Flood Management / by APFM The use of discount rate has become an integral part of CBA because a high discount rate tends to give a lower value to benefits which accrue after longer periods and result in giving more attention to the interests of future generations.
