a. Use a spreadsheet to calculate the durations of the two bonds in Spreadsheet 16.1 if the annual interest rate increases to 12%. Why does the duration of the coupon bond fall while that of the zero remains unchanged? (Hint: examine what happens to the weights computed in column F.)
b. Use the same spreadsheet to calculate the duration of the coupon bond if the coupon was 12% instead of 8% and the semiannual interest rate is again 5%.
Explain why duration is lower than in Spreadsheet 16.1. (Again, start by looking at column F.)
a. Footnote 5 presents the formula for the convexity of a bond. Build a spreadsheet to calculate the convexity of a 5-year, 8% coupon bond making annual payments at the initial yield to maturity of 10%.
b. What is the convexity of a 5-year zero-coupon bond?
