Part-Time Penalty in Sweden: Evidence from Quantile Regression

Abstract

This study analyzes the part-time penalty in Sweden using quantile regression. We find that the estimated part-time wage differential is negative across the whole wage distribution. OLS overestimates the part-time penalty at the bottom of the distribution, and underestimates it at the top. The estimated part-time wage gap rises across the distribution, and there is a sharp acceleration in the increase starting around the 75th percentile, especially for men. Consequently, we find evidence of a glass ceiling in part-time employment for both men and women in the Swedish labor market.
