为什么用的是△y/y,而不是△Y/Y?

NO.PZ2018091706000020

问题如下:

Economic data of a country is showed below:

According to the economic data, which of the three counties most likely rely on the capital deepening?

选项:

A.

Country X.

B.

Country Y.

C.

Country Z.

解释:

A is correct.

考点Cobb-Douglas production function 的变形公式

解析先写出变形公式

Growth rate of labor productivity= Growth rate of TFP+ Growth rate of capital deepening假设劳动力恒定不变

capital deepening%=y/y-T/T

X=2.6-0.8=1.8

Y=1.8-1=0.8

Z=1-(-0.1) =1.1

为什么用的是△y/y,而不是△Y/Y?△y/y是labor productivity的growth rate而△Y/Y是Potential GDP的,那为什么不用大写的这个Y呢?

嗨,努力学习的PZer你好:


为什么用的是△y/y,而不是△Y/Y?、

Hello,亲爱的同学~

△y/y是指人均GDP增长率,人均GDP增长率也就是劳动生产率。

△Y/Y是指总的GDP增长率。


本题公式为:

Growth rate of labor productivity= Growth rate of TFP+ Growth rate of capital deepening

Growth rate of labor productivity是人均,要用△y/y表示。


△y/y是labor productivity的growth rate而△Y/Y是Potential GDP的,那为什么不用大写的这个Y呢?

如果使用大写,则表示总的GDP增长率。

potential GDP增长率(△Y/Y) =  人均potential GDP增长率(△y/y)+ labor force growth rate
