RESUMO

This thesis is composed of three works, and they all use dynamic panel data estimation models. The estimation models used are the Generalized Moments system, developed by Arellano-Bond (1991), Arellano-Bover (1995) and Blundell and Bond (1998). The first work is entitled The Social Security system and Rural Poverty in Brazil, and it analyzes the impact of retirement through social security on poverty. The results indicate that rural retirement has no significant impact on poverty reduction, thus not corroborating the hypothesis which states that rural social security significantly decreases poverty. The second work is entitled Inequality Determinants in Brazil, and it aims to analyze the contribution of different determinants of income inequality reduction in the country. The results show that income transfers from the federal government do not affect the dynamics of income inequality in the period studied. When considering the other determinants, education was the main factor in reducing inequality. The second most important contribution was from income of all kinds of labor. The governments tax burden contributes to increase income inequality in Brazil. The third work is itled Economic Growth and Income Concentration: Its effects on Poverty in Brazil, and it considers the impact of variations in economic growth and income inequality on poverty alterations in Brazil. Since economic growth in itself is not capable of explaining alterations in poverty, the work takes income inequality into account as a complementary factor in analyzing poverty, aiming to evaluate Bourguignons (2002) hypothesis, which states that the higher the inequality in a country, the lesser the effectiveness of economic growth in reducing poverty will be. The results show that the inequality-poverty elasticity is greater than the income-poverty elasticity and the high inequality and low initial development levels of the majority of states are obstacles for reversing the poverty situation via income growth.
