Ceilings or floors? Gender wage gaps by education in Spain

Abstract

This paper analyzes the gender gap throughout the wage distribution in Spain using data from the European Community Household Panel. Quantile regression and panel data techniques are used to estimate wage regressions. In contrast with the steep increasing pattern found in other countries, the flatter evolution of the Spanish gender gap hides an intriguing composition effect. For highly educated workers, in line with the conventional glass ceiling hypothesis, the gap increases as we move up the distribution. However, for less-educated workers the gap decreases. We label this novel fact as a floor pattern and argue that it can be explained by statistical discrimination exerted by employers in countries where less-educated women have low participation rates.
