在生产哪种上面机会成本越低,就生产哪种商品.这个我没有理解.既然是比较优势,是不是应该横向比呢? 比如一个公司A 一个劳动力可以生产X 10个, B可以生产9个. 那么明显A的每单位成本更低啊? 不是吗? 如果按照老师说的算机会成本, 对于A公司, Y=2X, B公司Y=3X,就得出A公司生产X,那么逻辑上是不是有问题? 因为A和B每单位X的成本还不一定啊,怎么可以直接对比呢?
已回答在reading 25中 480页对于active risk的原版书有四句话,请老师详细解释下: ■ high net exposure to a risk factor will lead to a high level of active risk, irrespec- tive of the level of idiosyncratic risk; ■ if the factor exposure is fully neutralized, the active risk will be entirely attributed to Active Share; ■ the active risk attributed to Active Share will be smaller if the number of securi- ties is large and/or average idiosyncratic risk is small; and ■ the level of active risk will rise with an increase in factor and idiosyncratic vola- tility
