This paper sets out to estimate the GPG in EU countries based on a number of variables: the female participation rate, occupational segregation by gender, the proportion of people working in high-wage jobs and in education and health, plus the wage dispersion. The analysis covers 25 EU countries over 12 years from 2004 to 2015. The data are taken from three statistical surveys: the Labour Force Survey, the Structure of Earnings Survey and the EU-SILC. Three fixed-effect models and three random-effect models are estimated, based on an incomplete panel-dataset of 271 observations.
The key variables in explaining the GPG in the Southern Europe group are the female participation rate and the proportion of people working in high-wage jobs and in the Northern Europe group they are the female participation rate and the proportion of people working in education and health. By contrast, in the CEE country group the female participation rate is not significant and the most relevant explanatory variables are occupational segregation and the wage dispersion.
This paper finds evidence that comparisons between countries to determine GPGs have to take into account institutional and cultural factors, social roles and historical trends in national labour forces.
