The Neoclassical Growth Model Predicts That for Identical Savings Rates $\widehat { g 6090 } = \widehat { \beta _ { 0 } } + \widehat { \beta _ { 1 } } \times \operatorname { RelProd } _ { 60 }$

Essay

The neoclassical growth model predicts that for identical savings rates and population growth rates, countries should converge to the per capita income level. This is referred to as the convergence hypothesis. One way to test for the presence of convergence is to compare the growth rates over time to the initial starting level, i.e., to run the regression $\widehat { g 6090 } = \widehat { \beta _ { 0 } } + \widehat { \beta _ { 1 } } \times \operatorname { RelProd } _ { 60 }$ , where $g 6090$ is the average annual growth rate of GDP per worker for the 1960-1990 sample period, and $\operatorname { RelProd } _ { 60 }$ is GDP per worker relative to the United States in 1960. Under the null hypothesis of no convergence, $\beta _ { 1 } = 0 ; H _ { 1 } : \beta _ { 1 } < 0$ , implying ("beta") convergence. Using a standard regression package, you get the following output: Dependent Variable: G6090
Method: Least Squares
