Several explanations can be put forward for the high incidence of part-time work among women. First, there is a pronounced lack of all-day childcare and out-of-school-hours care supply, and unsubsidised care is very expensive (the highest in the OECD). As an example, children typically go home at lunch-time since school cafeterias are rare, making it difficult for a parent or a caregiver not to be home at that time.
