We find no impact on the extensive margin but do find one on the intensive margin. In particular, we find that access to full-day kindergarten increases weekly hours worked and decreases absenteeism for mothers of four-year-olds. We find that this effect is driven by specific sub-groups, namely non-immigrant mothers of only one child with low education levels who live in urban areas.}, keywords={maternal labour supply;early education;kindergarten}, }
