This paper examines the extent to which motherhood affects women's career accomplishments and wages in Italy and the UK. Using the EU-SILC 2009 data, a decomposition of the motherhood wage gap is implemented after accounting for double selection in labor market participation and motherhood. We find evidence of a negative correlation between labor market and fertility decisions. The results show that motherhood has no adverse effects on women's career path in Italy, and that job segregation explains most of the motherhood wage gap in the UK. Empirical findings suggest that the timing of motherhood and job continuity affect significantly the female wage profile.
