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: Country X.
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?
