Education is a key determinant of wage development. The relationship between education and wages is particularly strong in countries with vocationally oriented educational systems and a clear distinction between general and vocational education, such as Germany and Switzerland. However, whether...

This paper evaluates the gender wage gap among wage workers along the wage distribution in Georgia between 2004 and 2011, based on the recentered influence function (RIF) decomposition approach developed in Firpo, Fortin, and Lemieux (2009). We find that the gender wage gap decreases along the...

Test-retest reliability assessments rarely investigate whether reliability itself is stable or whether change in reliability affects findings from substantive models. Research across the social sciences often recognises that measurement error could influence results, yet it rarely applies...

In this paper I develop a new version of the Oaxaca-Blinder decomposition whose unexplained component recovers a parameter which I refer to as the average wage gap. Under a particular conditional independence assumption, this estimand is equivalent to the average treatment effect (ATE). I also...

Differences in wages between men and women, white and black workers, or any two distinct groups are a controversial feature of the labor market, raising concern about discrimination by employers. Decomposition methods shed light on those differences by separating them into: (i) composition...

This paper examines the contraction in the gender wage gap in Georgia between 2004 and 2011. Behind the continuous decline at the mean lies a change in the shape of the gender wage gap across the wage distribution before and after the 2008 crisis. Before the crisis, the growth in state sector...

This article reports the results of a replication of Bobbitt-Zeher’s 2007 article “The Gender Income Gap and the Role of Education”. Models that emulate the original specifications (by and large) reproduce the original results. However, models that adhere to Bobbitt-Zeher’s theory...

This study examines wage differences across Spain's regions along the entire wage distribution based on matched employer-employee microdata from 2006 to 2014. Unlike previous studies, we control for differences in regional purchasing power parities, which are very large in practice. Although...

We analyse the evolution and proximate determinants of labour income inequality in Mexico between 1989 and 2017. Labour income inequality increased between 1989 and 1994 and declined between 1994 and 2006. What happened after 2006 is subject to uncertainty. The national labour force survey shows...
