问题如下:

A return distribution of skilled managers that is highly distinct from the return distribution of unskilled managers, most likely implies a:

选项:

A.

highly efficient market.

B.

low opportunity cost of not hiring a skilled manager.

C.

high opportunity cost of not hiring a skilled manager.

解释:

C is correct.

When the two distributions are highly distinct, the unskilled managers are expected to significantly underperform the skilled managers, implying a high opportunity cost of not hiring the skilled managers. Efficient markets are likely to exhibit smaller differences of returns between skilled and unskilled managers.

老师,根据框架图,老师的意思是2类错误机会成本更高,2类错误是指雇佣了unskilled manager,那这道题解题思路怎么理解,这个地方很容易变不过来

嗨,从没放弃的小努力你好:


老师,根据框架图,老师的意思是2类错误机会成本更高,

2类错误的机会成本更高,理解正确。


2类错误是指雇佣了unskilled manager,

这里理解有误。根据框架图内容:

1类错误是指雇佣了unskilled manager 。

2类错误是指没有雇佣skill manager。


那这道题解题思路怎么理解,这个地方很容易变不过来

我们再看本题

熟练经理的回报分布与非熟练经理的收益分布非常不同,很可能意味着:

选项:

A.高效市场。

B 没有雇佣一个熟练的经理的低机会成本。

C 没有雇佣一位熟练的经理带来的高机会成本。


C选项的没有雇佣数量的基金经理,对应TypeII。

高机会成本也是TypeII的特征。

因此C选项正确。

没有雇佣到一个有能力的基金经理的机会成本不是很低吗? 因为影响不大,有很多人有能力,就意味着错过一个也不太影响,为啥B不对?
