看了各种提问,越看越糊涂

问题如下:

Economic data of a country is showed below

According to the economic data which of the three counties has the highest growth rate of potential GDP:

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growth rate of potential GDP= growth rate of labor force + growth rate in labor productivity

X=2.1+2.6=4.7

Y=1.5+1.8=3.3

Z=0.6+1=1.6

如果 growth rate of output = ΔY/Y

那么就应该是 growth rate of output = Δy/y + ΔL/L(这个是助教老师在2021年12月的回复);


但老师现在又说 ΔY/Y是GDP增长率,potential ΔY/Y是growth of potential GDP


所以 在原本的公式中,什么是growth rate of potential GDP,什么是 growth rate of output ?

计算公式又是怎么样的呢?

嗨,从没放弃的小努力你好:


结合本题,就只有growth rate of potential GDP? growth rate of output 是个干扰项?

growth rate of output 是个干扰项。理解正确

嗨,爱思考的PZer你好:


growth rate of potential GDP是指潜在增长率。取决于,劳动力、资本积累、技术

growth rate of output 是某一年的增长率。取决于,消费、投资、政府开支、净出口,C + I+ G + X-M


同学可能分不清这两个GDP的概念,老师画一张图同学就清楚了:
