问题如下:
A perpetual bond is a financial product that pays the same amount of money over an infinite period of time. Assume each month it pays $60, and the annual discount rate of 4% compounded monthly. The present value of this bond is:
选项:
A.$15,00
B.$18,000
C.undetermined
解释:
B is correct. The present value of a perpetuity is PV=A/r= $60/(4%/12)=$18,000.
题目中给出条件Assume each month it pays $60,就是说这个条件下,payment已经是按月度的了,与后面的y是一样的付息频率(按月),那为什么y还要除以12?我理解是直接用60/0.04就可以了。求老师解答。
