CFA考試中是需要考生掌握一定的知識(shí)的,考生在備考CFA一級(jí)中考試題做的如何?是不是掌握的很多知識(shí)呢?今天一起看看這道CFA考試題是怎么做的?

A profit maximum is least likely to occur when:

A average total cost is minimized

B marginal revenue equals marginal cost

C the difference between total revenue and total cost is maximized


答案:

A is correct. The quantity at which average total cost is minimized does not necessarily correspond to a profit maximum.

解題思路

Profit=TR-TC; ①當(dāng)兩者之差達(dá)到zui大值時(shí),說(shuō)明此時(shí)的profit為zui大值;②求導(dǎo)方法,TR'-TC'=0時(shí),此時(shí)profit達(dá)到zui大值,即MR=MC

易錯(cuò)點(diǎn)分析:

這道題不少同學(xué)都沒(méi)有看清least likely,zui后選擇錯(cuò)誤。選擇A是因?yàn)榕袛鄍rofit大小時(shí),不能單由cost判斷,還要考慮revenue和產(chǎn)量。Costzui低的時(shí)候,Revenue和產(chǎn)量可能同時(shí)比較小,如此總的Revenue就很低,那么利潤(rùn)也很低。
