What characterizes scale economies?

• A. Per-unit costs rise with volume.
• B. Per-unit costs decline with volume; followers must match the leader's price while having higher costs, making catch-up economically prohibitive.
• C. Costs stay constant as volume increases.
• D. They only apply to hardware industries.

Answer: (B)

Scale economies occur when increasing output lowers the average cost per unit. This happens because fixed costs can be spread over more units and operational processes often become more efficient as volume grows. The best answer captures this cost-advantage dynamic and the strategic consequence: as a leader operates at a large scale, it can price more aggressively, and entrants trying to catch up must reach similar scale while still incurring higher costs per unit, making competitive convergence economically prohibitive. In short, per-unit costs fall with volume, which is the hallmark of economies of scale. Other patterns—costs rising with volume, costs staying the same, or scale effects limited to specific industries—do not describe this phenomenon.
