This article analyses the cost of motherhood borne by Polish women. The cost of motherhood is defined as a drop in earnings caused by the presence of children. The findings show that motherhood in Poland is associated with a drop in women's net monthly earnings of around 13–19%. The results also show that the cost of motherhood varies with the number of children and the drop in wages is particularly high for mothers of three or more children. The investigation of mother's self-selection into employment suggests that the estimated cost would be higher if the choice could be accounted for.
We use cross-national data on 26 EU countries to assess how much children and the responsibilities related to them contribute to the gender wage gap, and how institutional elements - especially family policies - affect this relationship. Our analysis is based on a decomposition that reveals what portion of the gender wage gap may be attributed to: (1) the motherhood wage penalty, (2) the fatherhood wage premium, and (3) the gender wage gap among childless individuals. Our findings suggest that the variability in the magnitude of the gaps is closely related to the institutional context, pointing to different reasons behind the gender wage gap and policy implications. Southern EU countries have low gender wage gaps and low motherhood penalties or even premiums. Short leaves, low childcare coverage, and traditional norms do not support maternal labor supply, but mothers who work do not face a wage penalty. Western EU countries with higher childcare coverage, moderate length leaves, supportive norms, and flexible jobs have relatively high maternal employment and mothers are not faced with significant wage penalties. The highest motherhood penalties are found in CEE countries, where long leaves, low childcare availability under age 3, and preferences for within-family care lead to long absences from the labor market. In all countries, irrespective of cultural norms and policies, we find high positive family gaps among men, which drive men's average wages up, and lead to gender wage inequality.
AbstractWe examine how much children and the responsibilities related to them contribute to the divergence of men's and women's wages, and consequently, to the formation of the gender wage gap. To derive the relative contribution of gender‐specific parent gaps to the overall gender wage gap, we provide a modification of the Oaxaca–Blinder decomposition and include simultaneous corrections for selection into employment and parenthood. The results show that the fatherhood wage premium contributes most significantly to the gender wage gap, especially in Poland. The motherhood penalty is also significant, while the role of the gender gap among childless individuals is small.
