e. How would the price of the bond be affected by changing the going market interest rate? (Hint: Conduct a sensitivity analysis of price to changes in the going market interest rate for the bond. Assume that the bond will be called if and only if the going rate of interest falls below the coupon rate. That is an oversimplification, but assume it anyway for purposes of this problem 8% Nominal market rate, r: Value of bond if it's not called Value of bond if it's called The bond would not be called unless rscoupon We can use the two valuation formulas to find values under different r's, in a 2-output data table, and then use an IF statement to determine which value is appropriate Value of Bond If: Not called Called Actual value, considering $0.00call likehood: Rate, r$0.00 0% 2% 4% 6% 8% 10% 12% 14% 16%
