Child migration in the region has many contradictory aspects, as reported in the feature article of this bulletin. On the positive side, there are better educational opportunities in countries of destination and, in countries of origin, greater well-being thanks to remittances; greater protection gained by migrating away from situations of violence and social risk; and new horizons for broadening life experiences. On the negative side, there are precariousness and heightened family environment risks when the parents migrate and the children are left behind in the care of others; exposure to abuse and violation of rights during migratory processes; and possibly lower citizen status in receiving countries.

This article analyses the trend of unfair inequality in Brazil (1995-2009) using a nonparametric approach to estimate the income function. The entropy metrics introduced by Li, Maasoumi and Racine (2009) are used to quantify income differences separately for each effort variable. A Gini coefficient of unfair inequality is calculated, based on the fitted values of the non-parametric estimation; and the robustness of the estimations, including circumstantial variables, is analysed. The trend of the entropies demonstrated a reduction in the income differential caused by education. The variables “hours worked” and “labour-market status” contribute significantly to explaining wage differences imputed to individual effort; but the migratory variable had little explanatory power. Lastly, the robustness analysis demonstrated the plausibility of the results obtained at each stage of the empirical work.
