我用以下思路得出答案A,请帮忙看下为什么错,谢谢!NO.PZ2016031002000031 问题如下 The following spot anforwarrates have been given: Current 1-yespot rate is 6%. One-yeforwarrate one yefrom toy is 8%. One-yeforwarrate two years from toy is 10%.What's the value of a 3-year, 10% annual-pay, $1000 pvalue bon A.$996. B.$1,055. C.$1,086. B is correct.考点bonvaluation解析通过现金流折现求和,可得债券价格为1055.21,故B正确。Bonvalue=1001.06+100(1.06)(1.08)+1100(1.06)(1.08)(1.1)Bontext{ }value=\\\frac{100}{1.06}+\frac{100}{(1.06)(1.08)}+\frac{1100}{(1.06)(1.08)(1.1)}\\Bonvalue=1.06100+(1.06)(1.08)100+(1.06)(1.08)(1.1)1100=$1055.21 如题,老师我的算法是(1+y)三次方=(1+6%)(1+8%)(1+10%),算出来y=7.98% 然后n=3 pmt=100 FV=1000,算出来pv=1052,请问老师这种方法错在哪里呢?谢谢!

为什么不能 (1+S3)3次方 = (1+S1)*(1+1y1y)2次方*(1+2y1y)3次方 S3=18.06% 最后用计算器 N=3 I/Y=18.06 PMT=100 FV=1000 算PV呢 谢谢
