In the academic literature and professional practice, there are a number of alternative and apparently competing methods for valuing risky projects. In this paper, the authors compare and contrast three different approaches: risk-adjusted discount-rate analysis, opion pricing analysis, and decision analysis, focusing on the last two. They show that, in contrast to some of the claims made in the ‘real options’ literature, when both option pricing and decision analysis methods are correctly applied, they must give consistent results. The authors also explore ways in which option pricing and decision analysis methods can be profitably integrated. In particular, they show how option pricing techniques can be used to simplify decision analyses when some risks can be hedged by trading and, conversely, how decision analysis techniques can be used to extend option pricing techniques to problems with incomplete securities markets.
