Além de uma concentração de renda, a economia brasileira caracteriza-se por apresentar um alto grau de diferenciação salarial, superior ao encontrado em economias com níveis semelhantes de desenvolvimento. Em princípio, esta diferenciação poderia decorrer exclusivamente da heterogeneidade dos trabalhadores com respeito a determinados atributos produtivos. Entretanto, quando se controla por diferenças naqueles atributos produtivos que são observáveis, permanece inexplicada uma parte expressiva da desigualdade de salários, sugerindo a possibilidade de que existam trabalhadores igualmente produtivos recebendo remunerações distintas.
