Abstract: The total fertility rate is well below its replacement level of 2.1 children in high-income countries. Why do women choose such low fertility levels? We study howlabor market frictions affect the fertility of college-educated women. We focus ontwo frictions: uncertainty created by dual labor markets (the coexistence of jobs withtemporary and open-ended contracts) and inflexibility of work schedules. Using richadministrative data from the Spanish Social Security records, we show that womenare less likely to be promoted to permanent jobs than men. Temporary contracts arealso associated with a lower probability of first birth. With Time Use data, we alsoshow that women with children are less likely to work in jobs with split-shift schedules,which come with a fixed time cost. We then build a life-cycle model in which marriedwomen decide whether to work or not, how many children to have, and when to havethem. In the model, women face a trade-off between having children early and waitingand building their careers. We show that reforms that reduce the labor market dualityand eliminate split-shift schedules increase the completed fertility of college-educatedfrom 1.52 to 1.88. These reforms enable women to have more children and have themearly in their life-cycle. They also increase the labor force participation of women andeliminate the employment gap between mothers and non-mothers.
