这题答案里为何假设劳动力恒定不变?

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

这题为何假设劳动力恒定不变?难道不应该减去题目表格里的labor force growth rate作为劳动力变化率吗?

嗨,爱思考的PZer你好:

Hello,亲爱的同学!

这道题是使用劳动生产率进行计算的。

劳动生产率是指人均产出,已经人均了,就和劳动力数量有多少,没有关系了。


劳动生产率,约等于,资本 + 技术。
