Ct t X t , N NPV = t=1 tX t t (1 + i ) - I0 (13.3) and (13.2’) 3 13.3 Certainty equivalent method CAPM E( Ri ) = R f + (E( Rm ) - R f ) ( Xi im ) 2m = R f + (E( R m ) - R f ) Cov ( X i , R m ) ; Vi Vi Vi : market value of firm i Multiply V and rearrange the equation above, we can have Equation (13.4) V i= 0 i V = 2 [E( )] [Cov ( , )]/ R R X R m f i m m Xi Rf 0 2 0 [E( ) ] [Cov ( , )]/ R R X R m f i m m Xi Rf (13.4) (13.4’) (13.2’’) NPV Vi 0 I 0 If Rf = 10%, E(Rm) = 15%, X = $300, I0 =$2,000, Bj = 0.80, m=0.02, 0 then Cov ( X i , Rm) = (080)(0.02)(2,000) = 32, and from Eq. (13.4′) we have 2 V 0 i 300 - [(0.15 - 0.10)(32)] / 0.02 300 - (2.5)(32) 220 = $2, 200. 0.10 0.10 0.10 4 13.4 The relationship of the risk-adjustment discount rate method to the certainty equivalent method N NPV = t=1 tX t Xt Xt - , = = PV I t 0 t t t (1 + i ) (1 + r t ) (1 + r t ) (13.5) and (13.6) (1 + i )t (1 + i )t+1 , t+1 = t= t (1 + r t ) (1 + r t+1 )t+1 rt = 1+ i 1/ t t - 1, r t+1 = 1+ i 1/(t+1) t+1 -1 (13.7) and (13.8) (13.9) and (13.10) Under the Arrow (1971) and Pratt (1964) risk-aversion framework, α can be derived as E(z) - U ( X E ( z ) ) EU [ X ( Ez )], E ( z ) E ( z ), = E(z) Where E( z ) = Actuarial value of risk; X is asset; and U′ (X) and U′(X) are second and first derivatives with respect to utility function U(x) and (risk _ premium) 1 z2 [U ''( X ) ] 2 U '( X ) 5 13.4 The relationship of the risk-adjustment discount rate method to the certainty equivalent method Example 13.1 We assume that investors retain the same attitude toward risk over time, that is, α1 = α2 = α3 = 0.8. Then the risk-adjusted discount rate for the three periods is: r1 = (1 + 0.06) - 1 = 0.325, 0.8 r2 = (1 + 0.06) - 1 = 0.185, 1/2 (0.8 ) r3 = (1 + 0.06) - 1 = 0.142. 1/3 (0.8 ) Therefore the risk-adjusted rate decreases over time. Example 13.2 In the capital-budgeting process, we usually apply a constant riskadjusted discount rate to each period’s cash flows, r1 = r2 = r3. Assuming that this constant value is 0.185, we have: 1 = (1 + 0.06) = 0.8945; (1 + 0.185) 2 1 + 0.06 ] = 0.80; 2= [ 1 + 0.185 3 1 + 0.06 = [ ] = 0.716, 3 1 + 0.185 and we see that the value of the certainty equivalents will decrease over time. 6 13.5 Three other related stochastic approaches to capital budgeting 13.5.1 The Statistical Distribution Method ~ N Ct + S n Ct Sn NPV = I0 NPV = + - I 0, t N t N (1 + k ) (1 + k ) t=1 (1 + k ) t=1 (1 + k ) ~ N (13.11) and (13.12a) 1/2 + Cov ( , ) ( t) (13.12b) ] w w C C t t 2t N NPV [ t=1 N 2 t (1 + k ) N =1 t=1 Cov(Ct, Cτ) = ρτt στ σt, If the cash flows are mutually independent, then Eq.

NPV = N 2 yt m N (h) zt 2 ) +( t 2t t=1 (1 + k ) h 1 t=1 (1 + k ) (13.14) The derivation of Equation (13.14) is as follows Assume the net cash flow at time t, Xt, is related to the sources as follows X t Yt Zt (1) Zt (2) ... Zt ( m ) where Yt ,Zt (1) ,...Zt ( m ) follow normal distribution. The random variables for Yt are mutually independent while the random variables for Zt (1) ,...Zt ( m ) are perfectly correlated 8 2Xt N 2 NPV =[ t=1 (1 + k ) N N Cov ( X , X t ) ] t (1 + k ) (1 + k ) +2 2t =1 t=1 where 2Xt Yt2 2Z (1) 2Z ( 2 ) ... 2Z ( m ) t t t Cov ( X , X t ) Cov (Y Z (1) Z (2) ...

Depending on the correlation of the cash flows and the number of possible outcomes, they will all yield meaningful results. Simulation was introduced as a tool to deal with those situations in which the most uncertainty existed. Also discussed were various means of forecasting cash flows, most notably the product life-cycle approach. The emphasis in the later portion of the chapter was on the effects inflation has on the ability to forecast cash flows and on the appropriate discount-rate selection. We stress the importance of this factor as its nonrecognition can lead to disastrous results. In addition, we touched upon more theoretical issues by attempting to apply the CAPM, which created problems, but the basic approach is still applicable. 30 13.8 Summary and concluding remarks Lastly we investigated some of the more generalized meanvariance pricing frameworks and found that they were essentially equivalent. The application of these approaches is much the same as that of the CAPM, and further supports the increasing use of this technique in dealing with a very large, if not the largest problem area in applied finance theory, capital budgeting under uncertainty. The concepts, theory, and methods discussed in Chapters 12 and 13 are essentially based upon a myopic view of capital budgeting and decision making. This weakness can be improved by using Pinches’ (1982) recommendations. Concern should be given to how capital budgeting actually interfaces with the firm’s strategic positioning decision: to deal with risk effectively; to improve the control phase; and to take advantage of related findings from other disciplines. A broader examination of the capital-budgeting process, along with many effective business/academic interchanges, can go a long way toward improving the capital-budgeting process. 31 Appendix 13A.
