We estimate the returns to education for women and the racial wage differential among women over the wage distribution in Brazil by using quantile regression with semiparametric correction for sample selection. Our estimates show that the returns to education are high and that they are not...

In this paper, we evaluate the income convergence hypothesis in Latin America and East Asia between 1960 and 2000 through the use of quantile regressions to estimate growth equations. This approach allows us to assess how the effect of policy variables on per worker income growth rate can vary...

This article brings new inputs to debate outsourcing in Brazil, using a new methodology based on administrative records. With this methodology, it is possible to identify 4.02 million outsourced workers, corresponding to 11.7% of total employees in the urban private sector. Moreover, with this...

We study model selection strategies based on penalized empirical loss minimization. We point out a tight relationship between error estimation and data-based complexity penalization: any good error estimate may be converted into a data-based penalty function and the performance of the estimate...

This study aimed to the application of forecasts combination of model to predict tax revenues in Brazil. Here we combine the predictions obtained from three models: dynamic factor model (DFM), seasonal autoregressive integrated moving average (Sarima) and model of Holt-Winters smoothing. We...
