Decompondo o diferencial regional de salários entre Sudeste e Nordeste: uma aplicação da abordagem quantílica incondicional

Abstract

This paper investigates the regional wage gap in Brazil, focusing on the wage differences between the Southeast and Northeast regions. Based on the idea that this differential can be explained by differences in the composition of characteristics of workers and differences in returns (price) associated with these features, the analysis applies a method of unconditional quantile regression and decomposes the differential in different deciles of the wage distribution, following the method proposed by Firpo et al. (2007). The evidences suggest that the differences in individual characteristics explain a large portion of the wage gap between the regions analyzed, which corroborates the hypothesis presented in the most recent literature. However, the results obtained with the exercise of decomposition also attaches great importance to institutional factors related to the formalization and the differences in salary structure across regions.
