alpha没有给出,怎么计算capital deepening?

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

 yΔy=TΔT+kαΔk ,没有alpha,capital deepening (increasing capital per worker)?

嗨,努力学习的PZer你好:


同学你好,是包含的可以看下讲义106页,尽管公式里面有alpha但是文字表述里面完全没有表述alpha,是因为包含在capital deepening里面的。

就算太阳没有迎着我们而来,我们正在朝着它而去,加油!

嗨,从没放弃的小努力你好:


同学你好,这个题目的alpha是算进了capital deepening里面的了哦,细心看一下讲义,里面也是没有alpha的

----------------------------------------------
虽然现在很辛苦,但努力过的感觉真的很好,加油!
