Impact of Retirements and Pensions on the Social Welfare of the Households from Minas Gerais State

One of the main arguments for the existence of public social security systems relates to their potential use as income distribution and welfare policy tools. In this vein, several studies have sought to evaluate the effects of social security benefits on poverty and inequality. However, the evidence obtained from Brazilian studies regarding the effects of social security remains inconclusive, and studies evaluating the impact of social security on social welfare indices are scarce. The objective of this paper is to measure the impact of retirement and pensions provided by social security programs on the welfare level of households in the state of Minas Gerais, Brazil. The methodological approach is based on propensity score matching, and microdata from the National Household Sample Survey (Pesquisa Nacional por Amostra de Domicílios - PNAD, 2009) are used. The results demonstrate that income from retirement and pensions represents an important portion of beneficiary households' income, especially lower-income beneficiary households. The results suggest that social security has a positive effect on the incomes, access to knowledge and living conditions of the households analyzed. The impact of retirement and pensions on households in low-income groups (Classes D and E) tends to be more significant relative to the impact on middle class households (Class C).
