What is CBA?

Cost Benefit Analysis (CBA) is an appraisal method that provides analysis of social gains and losses that could arise from a project. The origins of CBA, arguably, date back to Dupuit (1844). Subsequent developments in cost-benefit analysis techniques were introduced in the U.S. by the U.S. Army Corp of Engineers. A consistent framework was developed through the US Rivers and Harbor Act of 1902 (Hammond, 1966).
