We propose alternative approaches to analyze residuals in binary regression models based on random effect components. Our preferred model does not depend upon any tuning parameter, being completely automatic. Although the focus is mainly on accommodation of outliers, the proposed methodology is...

We decompose annual average years of schooling series for Portugal into different schooling levels series. By estimating a number of vector autoregressions, we provide measures of aggregate and disaggregate economic growth impacts of different education levels. Increasing education at all levels...

Typically, studies on regional wage differentials are based on ordinary least squares (OLS) estimates. Quantile regression is an alternative approach which allows...

Unlike previous studies, in this paper we estimate the contribution of covariates for the regional wage decomposition components along the wage distribution employing a method first described in 2009 by S Firpo, N Fortin, and T Lemieu (<i>Econometrica</i> <b>77</b> 953–973). We consider the case of...

In this paper we use two alternative approaches to study the extent of gender wage discrimination in Portugal. Both methods involve the estimation of wage equations for males and females and the Blinder [1973] and Oaxaca [1973] decomposition. However, to take into account possible sample...
