Which concept describes lower average costs due to larger production volumes?

• A. barriers to entry
• B. external diseconomies of scale
• C. economies of scale
• D. diseconomies of scale

Answer: (C)

Lower average costs as output increases describe economies of scale. This happens because spreading fixed costs—like rent, machinery, and management overhead—over more units reduces the cost per unit. In addition, producing larger quantities can bring operational advantages, such as more efficient use of machinery, specialization of labor, and bulk purchasing of materials, all of which can push average costs down as volume grows. Barriers to entry are about obstacles that prevent new competitors from entering a market, not how costs change with production volume. Diseconomies of scale occur when growing too large raises average costs, often due to coordination problems or inefficiencies. External diseconomies of scale refer to costs caused by external factors (like congestion or higher input prices) as industry size expands. So the concept describing lower average costs from larger production volumes is economies of scale.
