Female labour force participation and fertility levels directly impact social security, especially when it relies on a pay-as-you-go scheme. In this paper, we quantify the impact of childcare subsidisation policies on a PAYG social security system. We build an overlapping generations model in which women decide how many children to have, the allocation of childcare time among different alternatives, and their labour force par-ticipation along the life cycle. We calibrate the model to Spanish data and use it to experiment with different childcare subsidisation policies. We find that childcare subsidies increase mother’s labour force participation and fertility minimally. Therefore, they have a negative effect on the present value of social security budget balance.
This paper quantifes the importance of changes in the sex ratio on married couples’ paid work, housework, leisure and marital sorting on education. To do so, I develop a model of marriage, bargaining and time allocation, and calibrate it to data for China, a country that has experienced a surge in boy births relative to girls’ since the 1980s. I perform a decomposition exercise and find that the change in the sex ratio explains up to one half of the decrease in married women’s paid work and half of the increase in their leisure time between 1990 and 2010, as well as one fifth of the increase in assortative mating. Moreover, in the model the changes in the sex ratio affect time allocation mainly through bargaining within the household and very marginally via marital sorting.
