不需要先例就可以知道这种宣布会有影响的,跟在哪个工业无关。有足够多的empirical evidence has foundthe effect significant.
A monopoly possesses “monopoly rent”, giving it an tremendous advantage to set very high prices, control the market share. Taking that away eliminates the rent, shrinks profit margin... On the other hand, it increases competition and lower consumer price in that industry. 这么大的事,对它的股票不会有影响吗?
It would be interesting to see how this one unfolds ~
我自己的401K也是有不少亚马逊的 :)
