1. Estimate the equation for per capita GDP growth derived from the Harrod-Domar model and provide a test statistic for the null hypothesis that the effect of population growth in the data is the same as what is predicted by the model.
2. Suppose the capital/output ratio in the economy is fixed and equal to 6. Based on the estimate you computed for Q1, can you reject that the coefficient on the savings/investment rate is equal to the model-implied coefficient at the 5% significance level?
3.Estimate the steady-state output per capita equation for the Solow model using the investment/savings rate and population growth. Assume that g+depreciation = 0.05, and remember to transform the variables in the data so they correspond to the objects in the Solow steady state equation. What is the coefficient on the investment rate?
4. Estimate the Solow model steady-state question like in the last question, only now include the log schooling enrollment rate as a control to capture "human capital." What is the coefficient on the savings/investment rate now?
5. What can we conclude from comparing the estimates from Q3 and Q4?
Question 5 options:
a | R squared increased when going from Q3 to Q4 which is the only thing we should think about when evaluating the model |
b | Adding human capital accumulation to the Solow model reduced the importance of measurement error in the investment rate |
c | Adding human capital accumulation to the Solow model improves the fit of the model in terms of the reasonablesness of the share of physical capital in output |
d | Human capital investment rate is likely to be negatively correlated with the physical capital savings/investment rate but positively correlated with output per capita |
