Salário de reserva e duração do desemprego no Brasil: uma análise com dados da PPV do IBGE

Abstract

The objective of this study is to analyze the main determinants of reservation wages and unemployment duration using as empirical evidence the PPV - Pesquisa de Padrão de Vida from IBGE (1996-1997). For this purpose, two econometric methodologies are used. For reservation wages, we estimate a traditional wage regression model whose main determinant used was unemployment duration. In order to attenuate simultaneity bias, two-stage regressions are used. The results show that unemployment duration negatively affects the workers’ reservation wages. This corroborates international evidence. Regarding the analysis of duration, we estimate proportional hazards models, with and without unobserved heterogeneity. The estimated parameters have the usual signals, except for the dummy for sex. The risk of leaving unemployment raises initially, and then, after including unobserved heterogeneity, shows a non-monotonic profile. These results offer a new perspective to try to understand the changes that have occurred in the Brazilian labor market during the 90’s.
