这道题为啥不是半年付息一次的，而是按照一年付息一次算呢，题目也没有明确说

问题如下：

The price of a three-year zero-coupon government bond is $85.16. The price of a similar four-year bond is $79.81. What is the one-year implied forward rate from year 3 to year 4?

选项：

A.

5.4%

B.

5.5%

C.

5.8%

D.

6.7%

解释：

ANSWER: D

The forward rate can be inferred from $P_4=\frac{P_3}{1+F_{3,4}}$, or${(1+R_4)}^4={(1+R_3)}^3(1+F_{3,4})$ . Solving, this gives $F_{3,4}=\frac{85.16}{79.81}-1=0.067$.
