Abstract

This paper seeks to analyze trends in sheepskin effects and earnings-education relationship on the Brazilian labor market from 1982 to 2004. Using data from the Brazilian National Household Sample Survey (Pnad) are estimated earnings equations including linear years of schooling, and splines and discontinuous functions for completed degrees, as well as semi-parametric regressions. Empirical evidence reports a reduction in the sheepskin effects from 1982 to 2004, indicating that a diploma or degree completion in Brazil has been loosing its value over time. At the same time, the relationship between log earnings and education has become more convex. Similar trends are verified when the analysis is carried out separately by region. Este artigo procura analisar tendências no efeito-diploma e na relação entre rendimentos e educação no mercado de trabalho brasileiro de 1982 até 2004. Usando dados da Pesquisa Nacional por Amostra de Domicílios (Pnad) são estimadas equações de rendimentos incluindo funções com saltos e mudanças de inclinação nos anos de educação correspondentes à obtenção de diploma ou à conclusão de um determinado grau, assim como regressões semiparamétricas. Os resultados mostram uma redução no efeito-diploma entre 1982 e 2004, indicando que a conclusão de um ciclo educacional no Brasil vem perdendo valor ao longo do tempo. Também, a relação entre o logaritmo dos rendimentos e o nível de escolaridade tem se tornado mais convexa.
