问一道题:NO.PZ2016010802000109 [ CFA I ]

问题如下图:

选项:

A.

B.

C.

解释:生产下降导致原材料价格下跌,这里的原材料是能源?还是能源以外的材料? 

还有,为什么要假设除非政府出手,否则ad不发生变动?长期生产萎缩导致需求下降不行吗?解答里面说的变动都是ad向右移动,是增加。为什么不考虑ad下降??

3 个答案

嗨,努力学习的PZer你好:


如上所述所有的影响AD平移的因素都应该使得AD向右平移,也就是增加,而不会反方向操作。否则就不符合一国当局的发展经济的初衷。

嗨,从没放弃的小努力你好:


政府干预肯定是要拉动总需求,而不是减少总需求,因为总供给下降,总需求再下降,那么经济就大步后退,这个经济体就会面临崩溃。


-------------------------------
加油吧,让我们一起遇见更好的自己!
