这道题应该是用多阶段的剩余价值模型计算，为何在计算PVof terminal value时，分子上的1.608不用乘以persistent factor 0.7？
无论是李老师的方法还是书本上的公式
pv(ri)=ri*w/(1+r-w)=1.608*0.7/(1+0.1-0.7)啊，然后再折现。
问题如下图：
选项：
A. 
B. 
C.

这道题用的是书上的公式（如下）：分子是2015年的RI,所以计算的是2014年的PVRI,折现3年到计算现值。

这道题不能用RI4乘以折现因子0.7来得到RI5吗

请问这里这样理解有问题吗
maggie_品职助教 · 2019年03月08日
不可以啊，没有RIT-1=RIT*w这个公式，计算RI需要使用RI自己的公式即RI=(roe-r)*B=ni-b*r

不可以吗？李老师不是说这里的w就理解成1+g，那为什么不可以呢？经典题R32的第二个视频的4分40秒您看下，板书上也有写这个RIt=RI t-1*W的公式

嗯，抱歉，我把你的问题看错了，以为你问用RI2014去计算RI2015. RI从2015年开始递减，那么RI5=1.608*0.7,请见我下面的计算

终于懂了，谢谢。

刚自己又做了一遍，终于做对了。这题太恶心了，因为2015年的RI是单独的，从2016年才开始衰减。相当于三阶段

T不是应该代表进入到第二段时间的时间吗？这道题的T难道不应该是2015吗？跟2016又有什么关系呀？2.我理解的是，下面黑色打印的这个公式T-1对应的就是2014年，用RI 2015计算对应2014年年底的PVRI然后折3年回去（也就是老师的红字部分），这个没问题。但是老师的解析我看写的“如果要使用李老师的公式，则需要向后推导一年，计算出RI2016以后才可以使用，并且折现的PVRI就会落在2015年年末，需要和2015年的RI=1.608一起折现4年到0时刻，就可以获得和本题一样的答案了”。这跟2016年有什么关系呢？如果2016年的话，不应该是RI(T+1）吗？既然是红色公式再向后一期推导出来的
