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...

Our objective is to analyse the role of teacher and school quality to explain differences in students' educational outcomes. With this aim, we use PISA microdata for 10 middle income and 2 high income countries and we apply decomposition methods in order to identify the role of these factors for...

Ethnicity wage gaps in Great Britain are large and have persisted over time. Previous studies of these gaps have been almost exclusively confined to analyses of household data, so they could not account for the role played by individual employers, despite growing evidence of their wage-setting...

Since the 1980s, income inequality in New Zealand has been a growing concern - particularly in metropolitan areas. At the same time, the encouragement of permanent and temporary immigration has led to the foreign-born accounting for a growing share of the population; this is disproportionally so...

The main goal of this paper is to document and analyze the long-term evolution of inequality of opportunity (IOp) in the four largest European economies (France, Germany, Great Britain and Italy). Relative IOp represents an important portion of total income inequality, with values ranging from...

This research examines wage differentials associated to different collective bargaining regimes in Spain and their evolution over time based on matched employer-employee microdata. The primary objective is to analyse the wage differentials associated to the presence of a firm-level agreement and...

In this paper I demonstrate, both theoretically and empirically, that the interpretation of regression estimates of between-group differences in economic outcomes depends on the relative sizes of subpopulations under study. When the disadvantaged group is small, regression estimates are similar...

The article examines public-private sector wage differentials in Spain using microdata from the Structure of Earnings Survey (Encuesta de Estructura Salarial). When applying various decomposition techniques, we find that it is important to distinguish by gender and type of contract. Our results...

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...

Recently, papers have started combining the naming of two popular decomposition methods: the Oaxaca-Blinder method and the Kitagawa method, a popular method in demographics and sociology. Although the two approaches have the same objective in terms of decomposing outcome differences in some...
