Application of the age-period-cohort model in the estimation of income mobility in Brazil

This work investigates the earnings mobility in Brazil, considering the period before and after the observed fall of inequality in the country. We used micro data from the National Household Sample Survey (PNAD), published by the Brazilian Bureau of Geography and Statistics (IBGE), from 1993 to 2007. We considered the trajectories of income for homogenous groups based on individual characteristics such as: date of birth, gender, race and schooling level. The estimation is done by age-period-cohort model. The combination of the characteristics of age and birth cohort emphasizes the role that education can have in higher income mobility, especially on the younger cohorts.
