“…Moreover, only few studies so far studied the mediating effect of total number of children (Amuedo-Dorantes & Kimmel, 2005;Buckles, 2008;Herr, 2016;Karimi, 2014), given common sample restrictions to earlier ages. Lastly, this study contributes to the discrepant evidence on the labour market effects of fertility timing in Europe (Bratti & Cavalli, 2014;Cantalini et al, 2017;Fitzenberger et al, 2013;Frühwirth-Schnatter et al, 2016;Karimi, 2014;Kind & Kleibrink, 2012;Leung et al, 2016;Lundborg et al, 2017;Nisén et al, 2019;Picchio et al, 2021;Putz & Engelhardt, 2014;Rosenbaum, 2021). This study is situated in the country context of the United Kingdom (UK), where public support for working mothers is weak as compared to other European countries (Brooks, 2012;Sigle-Rushton, 2008), leading to the expectation that motherhood timing may be consequential for mothers' earnings more similar to the US, and potentially also in the long term.…”
