13. 5.4 Theories of the term structure and their applications FN = (N)(YTMN) - (N - 1)(YTMN-1)(5.16′) Using figure 5.1 if YTM2=0.0487 and YTM1 =0.0491, then the forward rate for year 2 cab be calculated in terms of either eq.(5.16) or eq.(5.16’). eq.(5.16) F2 = (2)(0.0487) - (1)(0.0491) = 0.0483 eq.(5.16’) For the further information, please see chapter 15 of the book entitled “Investments” by Bodie, Kane, and Marcus, 9th ed.

15. 5.5 Interest rate, price-level changes, and components of risk premium • Imperfect-foresight case • Perfect-foresight case

16. 5.5 Interest rate, price-level changes, and components of risk premium (5.19) where =Annual rate of change in the GNP deflator; Y* = Level of real GNP; = Rate of change in real GNP; = Average change in the real money stock (nominal money stock deflated by the GNP deflator); Both equations (5.16) and (5.19) can be used to forecast future interest rate

17. 5.5 Interest rate, price-level changes, and components of risk premium (5.20) when Rt = Nominal rate of return in period t, Bt = Price of the bill in period t - 1, and Bt-1 = the price of the bill period t - 1.

18. 5.5 Interest rate, price-level changes, and components of risk premium (5.21) (5.22) Equation (5.22) can be rewritten as (5.22’) This equation is referred to Fisher effect.

20. 5.6 Three hypotheses about inflation and the value of the firm: a review • The debtor-creditor hypothesis • Economic theory suggests that unanticipated inflation should redistribute wealth from creditors to debtors because the real value of fixed monetary claims falls. • The tax-effects hypothesis • Since depreciation and inventory tax shields are based on historical costs, their real values decline with inflation. This, in turn, reduces the real value of the firm. • Operating-income hypothesis • According to the traditional view of economics, wealth transfers caused by general inflation are due primarily to those effects discussed above. We will discuss this hypothesis in chapter 6 eq. (6.8a) on page 192.

21. 5.7 Summary and concluding remarks In this chapter we have examined several concepts that will be of importance later. Determination of appropriate interest rates and risk premiums is very important in capital budgeting (Chapters 12 and 13), leasing (Chapter 14), and cost of capital determinations (Chapter 11). The mathematical concepts of arithmetic, geometric, and mixed means will also be important for estimating growth of dividends (Chapter 16) and financial planning and forecasting (Chapters 22 and 23). A basic understanding about the relationships between various types of risks (inflation, liquidity, and default) will be necessary for analyzing alternative risk premiums in financial analysis, planning, and forecasting.

34. Appendix 5B. Taylor-series expansion and its applications to rates-of-return determination (5.B.18) (5.B.20) (5.B.21) By using Taylor-series expansion, the relationship between HPR (y) with lognormal distribution and HPYc (x) with lognormal distribution can be shown as follows (5.B.22)

35. Appendix 5B. Taylor-series expansion and its applications to rates-of-return determination (5.B.22) (5.B.23) By using Taylor-series expansion, in the short time horizon, the discrete holding-period yield will equal to continuous holding-period yield.
