Which of the following is NOT a mechanism by which economies of scale reduce average costs?

• A. Specialization.
• B. Fixed-cost dilution.
• C. Improved efficiency.
• D. Inefficiencies in production.

Answer: (D)

Economies of scale lower the average cost per unit as output grows. This happens mainly through specialization (workers or machines focus on specific tasks, boosting productivity), fixed-cost dilution (the same fixed costs are spread over more units, reducing cost per unit), and improved efficiency (better processes, automation, and learning reduce input needs per unit). The option describing inefficiencies in production does not reduce average costs; it tends to raise them by causing delays, errors, or bottlenecks. So, that choice is not a mechanism by which economies of scale achieve cost reductions.
