问题如下:
2. Based upon Exhibit 1, capital deepening as a source of growth was most important for:
选项:
A.
Country A.
B.
Country B.
C.
Country C.
解释:
A is correct.
The associate economist can measure the effect of pure capital deepening by measuring the difference of the growth rates of labor productivity and total factor productivity (TFP). The larger the difference, the more important capital deepening is as a source of economic growth. From 2000–2010, Country A’s labor productivity grew by 2.4% per year, of which 0.6% came from TFP growth and 1.8% from capital deepening (2.4% – 0.6% = 1.8%).
考点:Cobb-Douglas production function 的变形公式
解析:先写出变形公式:
一国人均产出也就是劳动效率的增加来自于两个方面:资本深化以及技术的进步
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
最后计算结果是A国的数值最高(2.4% – 0.6% = 1.8%).这就表明A国对于资本深化最依赖,资本深化对于该国经济增长的贡献最大。
根据第一个函数 我的理解是,人均产出(y)是取决于资本深化和 科技进步。很明显 科技 和人均资本之间是相乘的关系,答案写相减 我没看懂是啥意思。 而且 为什么不能用 growth in gdp- growth in tfp - growth in labor productivity 得到 资本深化, 题目也没有明确说 growth in labour productivity 是人均 per ca[pita 呀
