老师,这个是生产函数的第一个变形公式对吗?

问题如下:

2. Based upon Exhibit 1, capital deepening as a source of growth was most important for:

选项:

A.

Country A.

B.

Country B.

C.

Country C.

解释:

A is correct.

The associate economist can measure the effect of pure capital deepening by measuring the difference of the growth rates of labor productivity and total factor productivity (TFP). The larger the difference, the more important capital deepening is as a source of economic growth. From 2000–2010, Country A’s labor productivity grew by 2.4% per year, of which 0.6% came from TFP growth and 1.8% from capital deepening (2.4% – 0.6% = 1.8%).

考点Cobb-Douglas production function 的变形公式

解析先写出变形公式

一国人均产出也就是劳动效率的增加来自于两个方面:资本深化以及技术的进步

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

最后计算结果是A国的数值最高(2.4% – 0.6% = 1.8%).这就表明A国对于资本深化最依赖,资本深化对于该国经济增长的贡献最大。

上课讲的第一个变形公式是乘积形式y=T·k的阿尔法次方,这道题又进一步变形为加和的形式?

嗨,从没放弃的小努力你好:

是的。

劳动生产率增长率 = 技术增长率 + 资本增长率。

这个公式教材正文上没提到,但是课后题有了。就补充记忆一下。
