Question

Choose the best answer for the following question:

How does a zero value discount rate affect the optimal rate of resource use over time?

A. Would lead to increased near term/current use as the current user cost decreases.

B. Would lead to equal per time period use as the current user cost is uniform over time.

C. Would lead to saving or postponement of use and drive up current user costs.

Answer 1

A zero-value discount rate would lead to equal per time period use as the current user cost is uniform over time. This is because, a value of discount rate greater than zero means that future value of an investment will be higher than what it is today. Similarly, present value of a future amount is lower today. However, when the discount rate itself is zero then user cost or user benefit shall be uniform over time.

Answer 2

Answer:

B. Would lead to equal per time period use as the current user cost is uniform over time.

Explanation:

• A zero discount rate means future benefits are valued equally to present benefits.

• This eliminates time preference, making the user cost (opportunity cost of using the resource now) the same across all periods.

• Thus, the optimal strategy is to use the resource evenly over time rather than overusing it now (A) or postponing it (C).

Key Concept:

• Discount rate = 0 → No preference for present over future → Balanced consumption
