In the allocation of capital to investment projects, it is unlikely that optimal decisions will be reached unless anticipated inflation is embodied in the cash-flow estimates. Often, there is a tendency to assume that price levels remain unchanged throughout the life of the project. Frequently this assumption is imposed unknowingly; future cash flows are estimated simply on the basis of existing prices. However, a bias arises in that the cost-of-capital rate used as the acceptance criterion embodies an element attributable to anticipated inflation, while the cash-flow estimates do not. Although this bias may not be serious when there is modest inflation, it may become quite important in periods of high anticipated inflation. The purpose of this note is to investigate the nature of the bias and how it arises.

3 We assume that no call feature exists on the instrument and that investors pay no taxes on dividends and capital gains.
4 In one study, Mundell, Robert, “Inflation and Real Interest,” Journal of Political Economy, LXXI (June 1963), pp. 280–283CrossRefGoogle Scholar, contends that nominal rates of interest may contain less than the full rate of anticipated inflation. The reason is that inflation may influence wealth variables in such a manner as to lower the real rate of interest.
5 Again, it is important to stress that we have assumed that the acceptance of the project does not alter the risk complexion of the firm as a whole.

10 Again, we have assumed that selection of the project will not affect the risk complexion of the firm as a whole.
11 If expected cash flows are expressed as a probability tree reflecting series of conditional probabilities over time, each possible future cash flow should embody an assumption with respect to the rate of future inflation. This rate should be treated as stochastic. The project then could be evaluated according to the expected value of net-present value and the standard deviation of the probability distribution of possible net-present values, where the risk-free rate is used as the discount factor. This risk-return approach can be extended to handle the marginal impact of a project on the expected value and standard deviation of the probability distribution of net-present values for the firm as a whole.
