3. [Points: 5+5] You have collected data for 104 countries to address the difcult questions of the determinants for differences in the standard of living among the countries of the world. You recall from your macroeconomics lectures that the neoclassical growth model suggests that output per worker (per capita income) levels are determined by, among others, the saving rate and population growth rate. To test the predictions of this growth model, you run the following regression: RelPersInc = 0.046 5.869 xn + 1.399 x+ 0.055 xEduc, R2=0.775, MSE = 0.1377 where RelPersinc is GDP per worker relative to the United States, n is the average population growth rate, 1980-1990, swig is the average investment share of GDP from 1960 to1990 {remember investment equals saving}, and Educ is the average educational attainment in years for 1985. Brazil has the following values in your sample: m = 0.40, n = 0.021, s35: 0.169, Educ = 3.5. (al.Does vour equation overpredict or underpredict the relative GDP per worker? Explain why?
