Brazil is one of the countries with the lowest intergenerational income mobility. This article aimed to analyze intergenerational income mobility in the 1982 Birth Cohort in Pelotas, Rio Grande do Sul State. Two methods were used, intergenerational income elasticity and quantile regressions, in order to measure heterogeneity in income mobility as a function of different levels of parents' past income. The results show relatively high income mobility for Brazilian standards. The main explanation is that the data cover the children's income at a younger age (about 23 years). Quantile regressions show higher social mobility in the intermediary social stratum. The results reinforce the notion of two opposite "traps", poverty and wealth.
巴西是代际收入流动性最低的国家之一。本文旨在分析巴西南里奥格兰德州佩洛塔斯1982年出生队列中的代际收入流动性。使用了两种方法,即代际收入弹性和分位数回归,以衡量作为父母过去收入不同水平函数的收入流动性异质性。结果表明,按照巴西的标准,收入流动性相对较高。主要解释是数据涵盖了儿童较年轻时(约23岁)的收入。分位数回归显示中间社会阶层的社会流动性较高。结果强化了贫困和财富这两个相反“陷阱”的概念。
