Strategic capital investment decisions are crucial to a business firm. The
decision to invest in privately financed infrastructure projects requires c
areful consideration, because they are exposed to high levels of financial,
political, and market risks. The project appraisal methods should incorpor
ate analysis of these risks. A number of capital-investment decision method
s can take risks into account, but each of them focuses on different factor
s and has its limitations. Thus, a more vigorous method is needed. A system
atic classification of existing evaluation methods shows that it is possibl
e to develop a new method-the net-present-value-at-risk (NPV-at-risk) metho
d-by combining the weighted average cost of capital and dual risk-return me
thods. The evaluation of two hypothetical power projects shows that the NPV
-at-risk method can provide a better decision for risk evaluation of, and i
nvestment in, privately financed infrastructure projects.
