Answer:
A) the formula to calculate modified duration of bonds:
modified duration = [1 - (1 + y)⁻ⁿ] / y
modified duration = [1 - (1 + 6%)⁻³] / 6% = 2.673 years
if you want to determine the Macaulay duration = modified duration x (1 + yield) = 2.673 years x 1.06 = 2.833 years
B) modified duration = [1 - (1 + 10%)⁻³] / 10% = 2.487 years
if you want to determine the Macaulay duration = modified duration x (1 + yield) = 2.487 years x 1.1 = 2.736 years
a. The duration should be 2.833 years.
b. The duration should be 2.736 years.
- The calculation is as follows:
Modified duration = [1 - (1 + y)⁻ⁿ] ÷ y
= [1 - (1 + 6%)⁻³] ÷ 6%
= 2.673 years
Macaulay duration = modified duration × (1 + yield)
= 2.673 years × 1.06
= 2.833 years
B) modified duration = [1 - (1 + 10%)⁻³] ÷ 10%
= 2.487 years
Macaulay duration = modified duration × (1 + yield)
= 2.487 years × 1.1
= 2.736 years
