This implies a need for change in child-care policy, from a welfare policy that primarily targets the poor to a positive public policy for the whole economy. However, there has been little research on this issue.1 There are signiﬁcant diﬀerences among regions that may lead to the imposition of drastic political changes. Observational data are limited, and cross-sectional data do not give a time-series perspective and may suﬀer from selection bias. Conducting a social experiment on fertility would be the best solution. However, such experiments are very expensive in terms of money and time.
