问题如下:
Economic data of a country is showed below:
According to the economic data, which of the three counties most likely rely on the capital deepening?
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:先写出变形公式:
Growth rate of labor productivity= Growth rate of TFP+ Growth rate of capital deepening(假设劳动力恒定不变)
capital deepening%=△y/y-△T/T
X=2.6-0.8=1.8
Y=1.8-1=0.8
Z=1-(-0.1) =1.1
老师,这道题的alpha去哪里了?为啥不考虑alpha,我看提问里的解答说是人均所以不考虑,怎么看出来的是人均?而且人均为啥就不需要alpha了?提问里还有一个提问,说是用另一个公式Y=T*K^a*L^(1-a),解析又说缺少alpha?这是咋回事呢?
