A Time Series Analysis of Household Income Inequality in Brazil 1977-2013 (original) (raw)

This paper addresses the importance of life cycle aspects in explaining the evolution of regional income inequality. The analysis of household microdata organized in age cohorts shows that Brazilian regional income inequality has different dynamics across generations, with income convergence being observed only for the older generations. The larger income share of younger generations produces a low speed of convergence in the country. When retirement payments, pensions, and other government transfers are excluded from income, convergence is not observed even for the older generations.

Patterns of inequality tend to seriously undermine any attempt at economic growth policy when the inequality is perceived by significant groups of individuals as unjust, inhuman, and insurmountable. One country with a high degree of inequality has been Brazil (usually in the world top-10). Brazil had also witnessed strong dynamics of certain indicators, such as the Gini coefficient, over the last several decades. However, so far, such dynamics have not been properly analyzed, especially considering the significant differences across Brazilian states. For filling that gap, this study used econometric techniques specific to time series and tried to identify structural breaks in the series of Gini coefficients for the 27 Brazilian states since 1976. Results showed a tendency towards an increase in inequality until 1995, followed by a reduction in inequality since 2000. Some cases of Brazilian states were related to the absence of structural breaks, showing a maintenance of historical t...

In this paper we analyze Pesquisa Nacional por Amostra de Domicílios Contínua (PNAD Contínua) Microdata from 2012 to 2018 to document how the mid-decade economic recession reversed the trend of pro-poor growth that dated back to the early 2000s. Since the recession, there was a rise in inequality and poverty levels and aggregate welfare decreased. While average incomes surged from 2017 to 2018, they were still below their peak in 2014. More than 80% of all income growth between 2015 and 2018 accrued to the top 5%. Most distributional statistics suggest Brazil in 2018 was either back at the same levels or even worse-off than in 2012. This paper also relies on decomposition techniques to investigate the immediate causes behind this reversal of fortune. We find that the effects of the recession on the labor market explain a lot of the recent changes, but public transfers also played a role in distributional dynamics – either by action or inaction. Social assistance transfers and unempl...

An income inequality coefficient is developed which includes explicitly the income and frequency series in the analysis to show the movements of the distribution of income. The algorithm gives additional analytical resources and permits improving approaches to social mobility, which includes evaluations of inequality and the market role. The coefficient has three parts: income effect, which describes the inequality measured by the income shares of the groups in the income series; frequency effect, which describes the inequality measured by the relative frequencies of the groups in the frequency series, and the interaction effect which measures the effect of the interaction of the two variables (income shares and relative frequencies). Temporal evaluation of the frequency effect may point to the movement (“mobility”) of individuals or groups from one distribution to another. Income distribution movements in Brazil were reevaluated and the proposed coefficient compared to other indicators.

The paper reviews the steady and widespread decline in income inequality which has taken place in most of Latin America over 2002-10 and which-if continued for another 2-3 years-would reduce the average regional income inequality to pre-liberalization levels. The paper then focuses on the factors, which may explain such inequality decline. A review of the literature and an econometric test indicate that a few complementary factors played an important role in this regard, including a drop in the skill premium following a rapid expansion of secondary education, and the adoption of a new development model by a growing number of left-of-centre governments which emphasizes fiscally-prudent but more equitable macroeconomic, tax, social expenditure and labour policies. For the region as a whole, improvements in terms of trade, migrant remittances, FDI and world growth playeda less important role than expected although their impact was perceptible in countries where such transactions were s...
