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
Growth rate in potential GDP=long-term growth rate of labor force+long-term growth rate in labor productivity,即Y变动率=y变动率+L变动率。那么,Y即potential GDP,难道不是等于output?
若不是,那么最后一列的ouput应该用什么来进行表示,或者在公式中如何体现?直接是actual GDP或者GDP?
