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
看完老师们的解答,我发现自己对公式理解有误,我一直把公式里的Y当作output,但实际上Cobb-Douglas production function和那些变形公式里的Y都是potential GDP 是吗?真实的output不是用这些公式算的。
