CFA備考中需要理解CFA知識,同時(shí)在做題檢驗(yàn)自己的學(xué)習(xí)成果,但是備考中不僅僅是需要做對CFA考試題,還需要考生能夠了解知道題的解題思路!

不知道你準(zhǔn)備的如何呢?和小編一起學(xué)習(xí)經(jīng)濟(jì)中的CFA考試題,看看你是不是能將這道CFA計(jì)算題做對呢?小編給你說CFA偏重基礎(chǔ)概念題,但是計(jì)算題也是有的哦!

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考試解題思路

這題主要考察以下兩個(gè)考點(diǎn),一個(gè)是是盈虧平衡點(diǎn)(breakeven point)。在完全競爭市場上,P=ATC是廠商的盈虧平衡點(diǎn)。而在P>ATC時(shí),利潤會吸引新廠商進(jìn)入。第二個(gè)考點(diǎn):單個(gè)廠商在完全競爭市場上均衡條件下有P =MR =MC=AC;根據(jù)此公式,本題聯(lián)立MC=AC 即可求出答案。

這就是CFA考試題需要了解解題思路哦!如果你在備考中需要相關(guān)的CFA考試題,這邊有CFA題庫可以幫助考生練習(xí)哦!
