Abstract

The aim of this paper is to estimate the adjusted sectoral wage gap in Poland in the period 1999–2012. We use a set of individual data from the survey on the structure of earnings by occupations (SEO) carried out by Central Statistical Office in Poland (CSO) every two years for entities with more than nine employees. We apply quantile regression and the Ñopo decomposition method to address several methodological problems of wage differential analysis. We show that, after controlling for structural differences in employment, there is no clear trend in the evolution of the adjusted public-sector wage premium in Poland in recent years. The parametric approach indicates a positive and growing premium, with significant variations across different parts of wage distribution. The non-parametric approach yields different results, indicating a negative premium with no clear trend in the period 1999–2012, with a declining public-sector wage penalty in recent years.
