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
Y 可以叫output,total production,potential GDP
ΔY/Y 可以叫growth of output,growth of total production,growth of potential GDP
y可以叫output per worker,labor productivity
这样理解对吗?
另外,Y、ΔY/Y 、y分别还有其他叫法吗?
