elsewhere if it had not been invested in the business. Therefore, an accountant’s estimate of total cost will be

191. Bob Edwards owns a bagel shop. Bob hires an economist who assesses the shape of the bagel shop’s average
total cost curve as a function of the number of bagels produced. The results indicate a U-shaped average total
cost curve. Bob’s economist explains that ATC is U-shaped for two reasons, the first being the existence of
diminishing marginal product, which causes it to rise. What would the second reason be? Assume that the
marginal cost curve is linear. (Hint: The second reason relates to average fixed cost)
ANSWER: Average fixed cost always declines as output rises because fixed cost is getting spread over a larger
number of units, thus causing the average total cost curve to fall.

explicit and implicit costs are included as opportunity costs.

~ANSWER:
An accountant would not include the forgone interest income that the money could have earned
elsewhere if it had not been invested in the business. Therefore, an accountant’s estimate of total cost will
be less than an economist’s.

The total cost curve will increase at an increasing rate, or in other words, the total cost curve gets steeper
as the amount produced rises.
TYPE: S KEY1:D SECTION:2 OBJECTIVE: 2 RANDOM:Y
190
~ANSWER:
Diminishing marginal product causes the marginal cost curve to rise.
TYPE: S KEY1:D SECTION:3 OBJECTIVE: 4 RANDOM:Y
191
~ANSWER: Average fixed cost always declines as output rises because fixed cost is getting spread over a
larger number of units, thus causing the average total cost curve to fall.
TYPE: S KEY1:D SECTION:3 OBJECTIVE: 3 RANDOM:Y
192
~ANSWER:
When average total cost curve is falling it is necessarily above the marginal cost curve. If the average total
cost curve is rising, it is necessarily below the marginal cost curve.
