One of the most important policy goals in industrialized countries is to increase the skill level of the labor force by life-long-learning strategies. In this paper our aim is to explain to what extent the variation in training investments is determined either by (observed and unobserved)...

This paper describes the application of a semiparametric approach, known as a varying coefficients model (Hastie and Tibshirani 1993), to implement a Oaxaca-Blinder type of decomposition in the presence of self-selection into treatment groups for a continuum of comparison groups. The flexibility...

This paper investigates the decrease in wage inequality among working age men in the Brazilian formal labor market by decomposing it into its permanent and transitory components. The permanent component refers to workers' productivity characteristics such as education and abilities, whereas the...

The Blinder-Oaxaca decomposition was developed in order to detect and characterize discriminatory treatment, and one of its most frequent use has been the study of wage discrimination. It recognizes that the mere difference between the average wages of two groups may not mean discrimination (in...

We estimate the gender pay gap with the traditional OLS based Blinder-Oaxaca decomposition, and with an extension using Random Forest (RF) regressions on Hungarian data for the years 2008-2016. Random Forests perform better as predictors out-of-sample and yield consistently lower estimates for...

Over the past years, the number of university graduates increased at an unprecedented rate in Great Britain. We analyse how this higher education (HE) expansion affected inequality in household net incomes in the 2000s. We show that, all else being equal, education composition changes led to...

Atkinson et al. (2018) propose a measure of the glass ceiling exploiting thattop incomes are approximately Pareto distributed. We clarify how this glass-ceilingcoefficient describes the increasing scarcity of women further up in the income dis-tribution and show how it relates to the top-income...
