자녀 연령과 기혼여성의 노동공급

초록

We study the effect of children’s age on their mother’s labor supply using the Korean Labor and Income Panel Study data. The result from an analysis using the Cox Proportional Hazard model shows that children’s age is closely related with their mother’s career interruption and return. A woman’s hazard rate of career interruption increases when she has a child younger than the school-entry age. The existence of a child whose age is less than one raises the hazard rate of career interruption more than twice. When a child is 0, 1, and 3 years old, the mother’s hazard of career return decreases significantly. Once a child’s age becomes 9, the mother’s hazard of career return rises. The findings imply that policy to reduce women’s career interruption and to help their career return should consider changes in women’s labor supply behaviors caused by their children’s ages.
