Theory Mathematical Model Econometric Model As income increases‚ consumption also increases‚ but not as much as income. yi = f ( xi ) = β0 + β1xi y i = f ( x i ) = β0 + β1x i +

Question1 Equation1 We are interested in investigating the relationship between income among countries in trade liberalization period and not in trade liberalization period. This equation 1 accommodates different intercepts and slopes for years after and before trade liberalization. Sigma‚ is the standard deviation of the natural logarithm of real per worker income and t for year. Dr is dummy-variable regressor or an indicator variable‚ is coded 1 for all years after the trade liberalization

Let’s relax this assumption and allow the covariance between Xi and ui to be dierent from zero. Our problem here is that ui is not observed. Doing OLS
