“…In particular, if a woman stays out of the labour force during the childbearing period, she loses the opportunity to accumulate job training and experience, and may be subject to atrophy and even depreciation (Gupta & Smith, 2002;Adda et al, 2017). Hence, by postponing childbearing, women tend to accumulate more work experience, and this strengthens their attachment to the labour market and helps raise their wages (Bratti, 2015). Moreover, in the context of an 'overlapping generations' model, Kimura and Yasui (2007) argued that since there is a tradeoff between education to accumulate skills and childrearing, as both are time-sensitive activities, a skilled worker tends to choose to have fewer children than an unskilled one, and thus a rise in the fraction of skilled workers would lead to a decrease in average fertility rate.…”
