Changes in quantity and quality of time for children: United States, 1981-1997.

This paper tries to analyze changes in the allocation of time decided by mothers and how their characteristics influence that allocation across the period 1981-1997 in the United States. Data reveals that there exists an increase on the quantity and quality of time devoted to children by some types of mothers. Shift-share analysis shows that behind the increase there is a change in maternal behaviour. Then, it seems reasonable to model the decisions of the mothers and try to explain which are the determinants. Estimations suggest that working time is a substitute of quantity, but not quality, of time with children. Being single reduces not only time but also its quality. Mother’s earnings and level of education have changed their influence on time with children across time.
