Using the Korea Labor and Income Panel Study (KLIPS) from 2000 to 2008, we estimate the Frisch elasticity of labor supply. Our point estimates of the intensive margin elasticity are around 0.23. The estimates are not sensitive to changes in household income and assets as well as changes in workweek regulation during the sample period that workers shall work for 5 days per week from Monday to Friday. We also estimate the extensive margin elasticity by considering labor market participation. We find that the point estimates at the extensive margin are greater than those at the intensive margin, but not statistically significant.

This paper investigates the possibility that children in school limit their mothers' labor supply. The theoretical background for the possibility is that mothers may choose to stay home if their time and monetary inputs on children's quality investment are poor substitutes for each other. The empirical findings suggest that labor supply of highly educated women and those with high household income is relatively suppressed by their children in school.

본 논문은 기혼여성의 경제활동 참가와 경제활동 참가 이후의 노동시간 공급을 결정짓는 요인을 분석하고, 그러한 노동공급행태의 시기적 변화를 살펴보았다. 이에 의하면, 학력이 높을수록 오히려 경제활동에 참가할 확률이 떨어지며, 6세 미만 자녀가 없을수록, 타소득수준이 낮을수록 경제활동 참가확률이 높게 나타난다. 미국의 경우 임금상승이 기혼여성 노동공급증가의 주요한 원인이라는 결론이 실질적으로 모든 연구에서 반복되어 왔으나 한국의 경우 실질임금수준은 크게 상승하지 않았음에도 불구하고 기혼여성의 노동공급이 이보다 빠른 속도로 증가했다. 그러나 1992년 분석결과에서 기혼여성의 취업구조가 다소 변화하고 있음을 확인할 수 있다. 무엇보다 시장임금수준이 높을 것으로 기대되는 여성일수록 경제활동 참가확률이 높아지는 경향이 뚜렷하게 나타난다는 사실이 1985년과 비교해 주요한 특징을 이룬다. 그러한 변화는 학력이 경제활동에 미치는 음의 효과가 여전하고 노동시간으로 본 노동공급이 시장임금의 변화에 영향을 받지 않는 것으로 나타난 점에서 상당히 완만하게 진행되고 있음을 알 수 있다.

This study analyzes the relationship between household debts and married female's labor supply. For doing this we construct effective interest rate faced by each household using interest paid amount and household financial debt amount. The effective interests rate for the households which have no financial debt are estimated by Heckman Selection model. The estimation results show that the increase in effective interest rate has led to the expansion of married women's the labor market participation. This suggests a possibility that negative scenarios resulting from an increase in interest rate can be partially offset by an increase in household labor supply and a rise in labor income.

This paper provides empirical evidence on the impact of SCHIP (The State Children's Health Insurance Program) on single mothers' working decisions using recent CPS (Current Population Survey) data during 1999-2005. SCHIP are found to have a significant positive impact on hours-worked decision.

This paper investigates how the provision of full child care subsidy to infants and toddlers differently affected female labor supply and fertility rate depending on the level of supply of child care centers in the place of residence. Our results on labor supply show that the higher the supply rate of childcare centers in residential areas, the higher the probability of career maintenance for multi-child mothers who are more likely to be admitted to a childcare facility. The results on the fertility rate show that the first child's fertility rate has increased since the support of childcare expenses in areas with higher rates of childcare centers. In the places where the supply rate of publicly-funded childcare centers is high, the second child's fertility rate has also increased significantly since the support of childcare expenses. This suggests that the quality of child care is an essential factor in determining the birth rate. Our results suggest that the effects of child care support on women's labor supply and fertility rate may differ depending on the priority of entering child care centers according to birth order and the degree of quantitative and qualitative supply of child care centers in the place of residence.

The 1995 tax reform in Korea has brought adjustment to the tax bracket, marginal tax rate, and tax deduction system which resulted in significant decrease in the income tax progressivity. In this paper we study the causal effect of the tax reform on male labor supply using difference-in-differences method. Using the data from Economic Active Population Survey (EAPS) and Daewoo Panel Data, we find about 1.5% increase in the hours worked of male wage workers.

This study estimates what fraction of the rise in household income inequality in Korean between 1996 and 2000 is accounted for by the change in each of the household income components, such as wages, employment, hours of work of household heads and spouses, household structure, and other incomes. The increased disparities of household heads' wages and labor supply explain, respectively, 70% and 34% of the rise in the difference in incomes between the top 10% and bottom 10% households. Changing labor supply of spouses, in contrast, was a strong countervailing force that diminished the measure of household income inequality by 21%.
