问一道题:NO.PZ2016010801000129

问题如下:

Due to significant economic change, the economy in long-run full-employment equilibrium will be affected due to an increase in aggregate demand. Which of the following statements about the effects in the short run is correct?

选项:

A.

The price level and real GDP will increase.

B.

The price level and real GDP will decrease.

C.

Only GDP will increase.

解释:

A is correct. There is a movement along the short-run aggregate supply curve, which increase the price level and real GDP at the same time.

考点:总需求

解析:短期总需求的提高,会同时提高价格水平和实际GDP产量。

题目里说的是long-run full-employment equilibrium,LRAS线应该是一条垂直的线吧,那么AD的向右SHIFT是不是只影响价格,而不影响GDP

同学你好,AD的变化沿着SAS移动最终达到新的LAS,新的LAS对应的price level 和GDP都增大

嗨,从没放弃的小努力你好:


同学你好,这道题之前老师也给过解答:

因为SAS是向右上方倾斜的,所以如果las向右移动,price level 和GDP都会增加,请知悉

虽然现在很辛苦,但努力过的感觉真的很好,加油!

请问为什么LAS也会跟着移动呢?不是AD沿着AS向右移动就好了吗?

请问老师我以下思路错在哪里 aggregate manincrease,根据A线,则price下降,在SRAS的曲线上move along,则price和reg都下降。
