READING 23 有兴趣去看

brightcool, goal-based investing 那道题,为什么不是regret呢? 书上讲goal-based那段就是用的regret 而不是mental 啊?

goal based = mental accounting

书上说mental accounting 是risk profiling会遇到困难的原因,而没有说是behavriou bias啊? 相反,在后面具体分析behaviour bias的时候提到了regret. 如果题目问的是behaviour bias, regret这个选项会不会更好?

real after tax required return:     209,670/4,350,000=4.82%

 

nominal after tax required return: 4.82+3=7.82%

我觉得最后不应该加3%, 算出的4.82%就是norminal rate. 原因是在计算living expense 时,已经考虑3%的inflation 了. outflow: living expense:      -110,000(cant remember the number)*1.03=xxxxx. brightcool 请来讨论一下. 如果加上3% 就意味着living expense 实际上被inflate 了两次

这个我告诉你，肯定要加。题目里面要求protect purchasing power.一开始的living expense加3%，你算出来的return只是cover了living expense的inflation。但是要求你不仅是要cover living expense，还要保护本金

倒霉,开始都加了3%,最后改掉了
