Brazilian labor market informality: a review of the literature. The economic literature relative to Brazilian labor market informality is very disperse and presents a significant lack of organization. In that sense, the purpose of this paper is to organize and discuss on a systematic way the main pieces of literature concerning informality in the Brazilian labor market using, whenever it is possible, the international literature as a comparison point for the existing results relative to Brazil’s experience. More specifically, questions related to wage differentials between formal and informal workers, labor market segmentation and the effect of institutions on the informal sector are emphasized.
