Some Pitfalls of Practical Benefit-Cost Analysis

Abstract

Practitioners of benefit-cost analysis face many difficulties. Despite the best training, guidance, and intentions, practitioners can stumble: actual benefit-cost analysis is hard and mistakes get made. Over the years, I have collected the mistakes I have seen in actual benefit-cost analyses. Many of the same mistakes occur over and over: the pitfalls of practical benefit-cost analysis. In this paper, I describe common pitfalls and suggest ways to avoid them.
