EAR都是用离散复利计算吗,讲义上在哪有介绍

NO.PZ2016082402000001

问题如下:

An investor buys a Treasury bill maturing in one month for $987. On the maturity date the investor collects $1,000. Calculate effective annual rate (EAR).

选项:

A.

17.0%

B.

15.8%

C.

13.0%

D.

11.6%

解释:

ANSWER: A

The EAR is defined byFVPV=(1+EAR)T\frac{FV}{PV}={(1+EAR)}^T . So (FVPV)1T1{(\frac{FV}{PV})}^\frac1T-1  EAR =  . Here, T = 1/12. So, EAR =   (1,000987)121=17.0%\;{(\frac{1,000}{987})}^{12}-1=17.0\%

这是以前的练习题,由于目前原版书和讲义里都找不到这个点了,我觉得按以前出现的例题用离散就行,而且考试时候不会有歧义选项的。

同学你好,这个讲义里没写,原版书里也没写,应该是早期的原版书的内容,不过这种一般都是离散着来的,毕竟截取的是1/12年。用连续和用离散的误差也不会影响考试做题的。
