Milton Friedman 【Price Theory】
引用“Consider the case of a monopolist. Without any knowledge of his cost curves, one can immediately conclude that he never would be operating in the inelastic protion of his demand curve. In such a portion, the reciepts would be less than at a higher price, while total costs would clearly be no less, since it can in general not cost more to produce a smaller quantity than a large (one could always produce the smaller quantity by producing the larger and disposing of the excess). However, if one were to choose which industry to monopolize, he would choose one for which the demand curve was highly inelastic at the competitive price. Once a successful monopoly had been established, price would be raised so as to operate in the elastic portion of the demand curve (the exact point in the elastic region will, of course, depend on cost conditions).”

为什么选择需求曲线高度缺乏弹性的行业？

顶起来了。。。。。。。

弹性小提高价格需求不会减少很多，所以利润会增加

这个东西我垄断，而且你非卖不可。  这还不好吗？

y axis is price, x axis is quantity.
   draw the demand curve or just the demand line.
the mid-point of the D line is elasticity=1
the part above this point is elasticty<1, that is, inelasticity.
then u can randomly choose two point at this part of line.
u can find that, price will change alot with a smaller change in quantity.
  
thats my inteprelation... i am not sure i am doing that by the right way but i hope i may somehow inspire u .... lol

我现在懂了~
谢谢各位老师~

在竞争价格的时候需求非常缺乏弹性，那么从竞争价格向垄断价格（高于竞争价格）的运动（提高价格）带来的是总收入的提高，垄断才有意义。
所以“ if one were to choose which industry to monopolize, he would choose one for which the demand curve was highly inelastic at the competitive price. ”

原来是这么理解的，我明白了
