Human Capital Gini coeffic<br />
Figure 1: Human Capital Inequality and Average Fertility Rates<br />
inequality may affect growth not only through a discouraging effect on physical<br />
capital investment rate but also through a positive correlation with the fertility<br />
rate, in Table 7 the investment and fertility rates are exclu<strong>de</strong>d from the set of<br />
explanatory variables. As a result, the coefficient of the human capital Gini<br />
in<strong>de</strong>x in all estimated equations is negative and statistical significant. Column<br />
(1) of Table 7 displays the long-term results in the OLS cross-section estimation<br />
where, controlling for other variables, the coefficient of the human capital Gini<br />
in<strong>de</strong>x collects the effect of an increase in human capital inequality in 1960 over<br />
the average growth rate in the subsequent 25 years. Un<strong>de</strong>r the presence of<br />
country-specific effects the coefficients of the OLS estimations are inconsistent,<br />
for this reason column (3) shows the results of the fixed effect mo<strong>de</strong>l, which<br />
also reports a negative and statistically significant coefficient for the human<br />
capital Gini in<strong>de</strong>x. However, the presence of the lagged <strong>de</strong>pen<strong>de</strong>nt variable<br />
as an explanatory variable makes the fixed effect mo<strong>de</strong>l also inconsistent. In<br />
addition, most of the explanatory variables should be treated as endogenous<br />
since their coefficients may indicate a problem of reverse causation. Columns<br />
(4) and (5) display the results of the first differences and system generalized<br />
Since the initial human capital Gini coefficent may be picking up the level of <strong>de</strong>velopment<br />
of the country, we also run a regression controlling for the initial income per capita. The<br />
coefficient of the human capital Gini in<strong>de</strong>x in this regression continues being positive and<br />
statistically significant with a value of 3.402 and a robust standard error equal to 0.590, the<br />
R 2 is 0.729.<br />
