An economic forecasting firm has estimated the following equation from historical data based on the neoclassical growth model:
Potential output growth = 1.5 + 0.72 × Growth of labor + 0.28 × Growth of capital
The coefficient on the growth rate of labor (0.72) in this equation is best interpreted as:
选项：
A.the labor force participation rate.
B.the marginal productivity of labor.
C.the share of income earned by labor.
解释：
C is correct.
In the standard Solow growth accounting equation, the coefficient on each factor’s growth rate is its share of income.
考点：柯布道格拉斯函数的变形表达式
解析：本题直接考察1-α的定义，它代表劳动力对于总收入（总产出）的贡献占比。
啥意思呢0.72
