规模经济

NO.PZ2016010801000025

问题如下:

Healthy Co. is a factory which producing health care products. The long-run average total cost is $15 per unit and total output is 500 units. The manager plans to increase the total output to 600 units. After some calculation, it is expected that the long-run average total cost will increase to $18. Which of the following description about Healthy Co. is most appropriate?

选项:

A.

Healthy Co. is experiencing the constant returns to scale.

B.

Healthy Co. is experiencing the diseconomies of scale.

C.

Healthy Co. is experiencing the economies of scale.

解释:

B is correct.

When the scale of the business increases (at 600/500-1=20%), the average unit costs increases (at 18/15-1=20%) as well. An upward-sloping long-run average total cost curve means diseconomies of scale.

考点:规模经济。

解析:产出上涨了600/500-1=20%,平均销售成本也上涨了18/15-1=20%

注意到平均单位成本的上涨就意味着企业运行在规模不经济的阶段。

题目说的是计划增产,通过计算如果增产那么单位成本就会增加。

也就是当前已经是处于规模经济阶段了,如果按计划增产,就会进入规模不经济啊。不是吗?

嗨,努力学习的PZer你好:

Hello,亲爱的同学~

产出上涨了600/500-1=20%,平均销售成本也上涨了18/15-1=20%

意思是,产出上涨会引起成本是上升。

根据规模不经济的定义,现在已经处于规模不经济的阶段了。

如果按照计划增产,依然是规模不经济。现在应该减产才对。


因此选B,现在正在经历规模不经济。

单位成本都是33.3,500/15,600/18,单位成本不变不应该是规模经济吗
