Correcting for Hubris in Project Appraisal

Behavioral finance research stresses the prevalence of overconfidence in capital budgeting practices. To remedy this shortcoming, specifically the upward bias in cash flow forecasts, the extant literature emphasizes the reduction of such forecasts. This paper considers the conditions under which a different adjustment is warranted, namely, an upward correction in the hurdle rate employed to evaluate the project. It is argued here that if adverse events can have a long-term, versus a merely transitory, deleterious effect on the project's cash flows, the second adjustment is appropriate.
