QuestionAfter expanding into a new region, a manufacturing company established
local assembly lines and hired local staff. Two years later, the
company's sales had grown as expected, but its operating margin had
decreased from 16 to 13 percent. The company's situation is most likely
due to:
选项：
A.Not reaching its breakeven volume yet.
B.Experiencing diseconomies of scale.
C.Achieving its minimum efficient scale.
解释：
Solution
- Incorrect. The company's operating margin is positive, indicating that it is generating profits. Therefore, it is operating above its breakeven volume.
- Correct. The company is most likely experiencing diseconomies of scale. The duplication of costs in each location and the need to target different demographics have led to increased fixed costs, surpassing the growth in output and resulting in diseconomies of scale.
- Incorrect. The minimum point on the long-run average cost (LRAC) curve is referred to as the minimum efficient scale. Since the company's profits have decreased after the expansion, it is not yet operating at the least-cost point, and therefore, it has not achieved its minimum efficient scale.
• determine and interpret breakeven and shutdown points of production, as well as how economies and diseconomies of scale affect costs under perfect and imperfect competition
A不正确的。该公司的营业利润率为正，表明它正在产生利润。因此，它的运营高于其盈亏平衡量。
B正确的。该公司很可能正在经历规模不经济。每个地点成本的重复和需要以不同的人口为目标导致固定成本增加，超过了产出的增长，造成规模不经济。
C不正确的。长期平均成本(LRAC)曲线上的最小点称为最小有效规模。由于公司在扩张后利润有所下降，所以还没有达到最低成本点，也就没有达到最低效率规模。
为啥营业利润下降说明单位成本升高？
