10. The Costs of Production
Average Total Cost: Short Run and Long Run
Multiple Choice
Why might a software company experience lower average costs as output expands?
A
High upfront development (fixed) costs are spread over many users while the marginal cost of distributing additional copies is very low, plus network effects and learning lower average cost.
B
Because marginal costs rise quickly with each additional user due to licensing and per-user fees, forcing average costs down.
C
Because fixed costs increase with output, and increasing fixed costs by itself lowers average cost per unit.
D
Because programmers face strong diminishing marginal returns that reduce average cost as more software is produced.
Verified step by step guidance1
Step 1: Understand the concept of average cost (AC), which is total cost (TC) divided by the quantity of output (Q), expressed as \(AC = \frac{TC}{Q}\).
Step 2: Recognize that in software production, there are high fixed costs (such as development and design) that do not change with the number of copies produced, and very low marginal costs (the cost of producing one more copy).
Step 3: Since fixed costs are spread over more units as output increases, the average fixed cost per unit decreases, which lowers the overall average cost.
Step 4: Consider additional factors like network effects, where the value and efficiency of the software increase as more users join, and learning effects, where production and distribution become more efficient over time, both contributing to lower average costs.
Step 5: Contrast this with scenarios where marginal costs rise quickly or fixed costs increase with output, which would not lead to lower average costs; thus, the key reason is the spreading of high fixed costs over many users combined with low marginal costs.
