老师好 百题case 2 第三题 文章中提到$15,000的statutory allowances 这个限制条件为什么没用？至少这部分的gift不用被tax吧？为什么答案里这部分也算tax了 感觉分子gift应该分两部分 缴税（1-tg)*85% + 不交税 就 *1 然后 再乘以 （1+rg(1-t))^20； 然后第四题其余两个选项为什么不对？谢谢

您好，能帮忙讲讲这道课后题的三个选项吗？谢谢

课后题19页8题讲一下解答内容怎么写

R27第31题，Aspen的描述中是不是还有另外一个问题，“We pursue a passive investment strategy, which seeks to identify and exploit structural inefficiencies through identifying mispricings created by loss aversion”这里mispricings created by loss aversion 应该是behavioral inefficiencies 吧？书上说：“Behavioral inefficiencies are perceived mispricings created by the actions of other market participants, usually associated with biases, such as trend following or loss aversion.

Structural inefficiencies are perceived mispricings created by external or internal rules and regulations. These inefficiencies can be long lived and assume a continuation of the rules and regulations rather than a convergence.”
