不知道你准备的如何呢?和小编一起学习经济中的CFA考试题,看看你是不是能将这道CFA计算题做对呢?小编给你说CFA偏重基础概念题,但是计算题也是有的哦!

The demand schedule in a perfectly competitive market is given by P=93-1.5Q (for Q62)and the long-run cost structure of each company is:

Total cost: 256+2Q+4Q2

Average cost: 256/Q+2+4Q

Marginal cost: 2+8Q

New companies will enter the market at any price greater than:

A 8

B 66

C 81

答案:

B is correct. The long-run competitive equilibrium occurs where MC=AC=P for each company. Equating MC and AC implies 2+8Q=256/Q+2+4Q.

Solving for Q gives Q=8. Equating MC with price gives P=2+8Q=66. Any price above 66 yields an economic profit because P=MC>AC, so new companies will enter the market.


CFA考试解题思路

这题主要考察以下两个考点,一个是是盈亏平衡点(breakeven point)。在完全竞争市场上,P=ATC是厂商的盈亏平衡点。而在P>ATC时,利润会吸引新厂商进入。第二个考点:单个厂商在完全竞争市场上均衡条件下有P =MR =MC=AC;根据此公式,本题联立MC=AC 即可求出答案。

这就是CFA考试题需要了解解题思路哦!如果你在备考中需要相关的CFA考试题,这边有CFA题库可以帮助考生练习哦!
