Question 1

What happens to average total cost when a firm experiences diseconomies of scale?

Accepted Answer

When a firm experiences diseconomies of scale, average total cost rises as output increases. This occurs because costs grow disproportionately faster than output. For example, if a car manufacturer doubles production but triples costs, the average total cost per unit increases, causing the long-run average total cost curve to slope upward.

Question 2

Why do larger firms face coordination and quality challenges that increase costs?

Accepted Answer

As firms expand, managing a larger workforce becomes more difficult, requiring additional executives and increasing overhead costs. Ensuring consistent quality at higher output levels becomes increasingly complex and costly. Bureaucratic layers slow decision-making, and employees focus more on following protocols than discovering efficient innovations, all driving costs upward.

Question 3

How does the long-run average cost curve shape reflect different economies of scale?

Accepted Answer

The long-run average cost curve is U-shaped. Initially, firms experience economies of scale with falling average costs. Then, average costs remain constant during constant economies of scale. Finally, at very high output levels, diseconomies of scale cause average costs to rise, creating the characteristic U-shape.

Question 4

What is the difference between diseconomies of scale and constant economies of scale?

Accepted Answer

Diseconomies of scale occur when costs increase disproportionately with output, raising average total cost. Constant economies of scale occur when long-run average total cost remains constant as output increases. For example, a shipping firm with independent ships experiences constant economies of scale because per-unit costs stay the same despite fleet expansion.

Question 5

How do bureaucratic processes contribute to diseconomies of scale?

Accepted Answer

Additional approval layers in larger organizations slow decision-making and increase costs. Employees become focused on adhering to protocols rather than finding innovative, more efficient ways of working. This reduced focus on efficiency and innovation drives up operational costs as the firm expands.

Question 6

What is the defining characteristic of diseconomies of scale?

Accepted Answer

Diseconomies of scale occur when doubling output requires more than doubling costs, causing per-unit costs to increase. This disproportionate cost increase is the opposite of economies of scale and results in an upward-sloping long-run average total cost curve at higher production levels.

Question 7

How does firm expansion affect departmental coordination and decision-making speed?

Accepted Answer

As firms expand, coordinating between various departments becomes increasingly complex. More executives must be hired to manage the larger organization, increasing costs. Additional bureaucratic approval layers slow response times, preventing quick decision-making and reducing the firm's ability to adapt efficiently to market changes.
