Uma análise dos determinantes da migração entre estados do trabalhador informal brasileiro

Abstract

This paper aims to estimate the probability of interstate migration of informal workers. More specifically, it has the objective to analyze the probability of migration according to the income level of the destination states. This goal is motivated by the fact that Brazil has a strong internal migration, which leads to the need of understanding if the characteristics of the internal migration are the same if one considers only the informal sector, which presents peculiarities. This way, a probabilistic model of migration is made based on a database from the Ecinf (IBGE/2003). Initially, it is estimated a simple probit model, in order to understand the impact of observed personal, job and regional characteristics on the individual's decision to migrate. After that, it is estimated a multinomial model, trying to understand the impact that these observed characteristics have when the destination of the migration is differentiated by the income level of the states. The main results show that, among informal workers, the migration has characteristics similar to those observed in the literature and in the proposed model, as being more likely among women, and presenting higher incomes among the migrants when compared with non-migrants, and that being an important variable for migration to richer regions. On the other hand, the results also show that, among the informal workers, increasing of the educational level of the individuals tends to reduce the probability to migrate, against what is observed in other job markets.
