T. ZWANE is used to address possible endogeneity bias due to reverse causation between earnings and education. Aft er controlling for endogeneity, we found that an additional year of education increased an individual's earnings by 37.8 % in the full sample. Interestingly, the coeffi cient of education was found to be positive and statistically signifi cant in both samples (urban and rural), reinforcing the results of the full sample. However, despite the coeffi cient of years of education being similar in direction (positively associated to earnings) across all samples, our results show that the education impact on individual earnings was higher in absolute values in urban areas. Th us, the 44.4 % increase of returns to education in the urban subsample was signifi cantly higher than the increase of 33 % observed for the rural subsample. Th ese results were to be expected, given the fact that South Africa is still battling the impact of the institutionalised policies of apartheid. In addition, we found that household size, head of household's age and whether the head of household was married were important factors positively infl uencing earnings in both territorial subsamples. Th e policy implications derived from our empirical results suggest that the government should invest more heavily in academic infrastructure, particularly in rural areas where the poor live, so as to improve the educational attainment in those areas.
