Answer: c. greater because interest rate changes have a greater impact on distant cash flows than near-term cash flows.
Step-by-step explanation:
Interest rate changes have a greater impact on distant cashflows because those cashflows will be exposed to the interest rates for longer. This means that they will be subjected to more discounting than a cashflow that is due in one year which would be subject to only a single year of discounting.
For instance, assume the required rate of return for two investments is 10%. One investment yields $10,000 in 20 years and another yields $10,000 in 2 years .
The present value of both are:
= 10,000 / (1 + 10%)²⁰ = 10,000 / ( 1 + 10%)²
= $1,486.43 = $8,264.46
Notice the difference. The longer term investment was more exposed to interest rate effects.
