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 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%.

To prevent the disincentive of labor supply under the current welfare system, we suggest the safety income system, a Korean version of negative income tax. Under the proposed system, for example, a household with four members whose annual income is less than 50 million wons will get financial support from the government. Under the safety income system, labor supply increases and so does the gross domestic product. The disposable income of low-income households increases, which alleviates the income gap among households. Analyzing the Household Income and Expenditure Survey data, we show that under the safety income system the disposable income differentials among households are reduced much more than under the current welfare system or under the universal basic income system.

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.

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.

청년실업, 명예퇴직, 노인취업문제 등 나이고하를 막론하고 모든 연령층에서 노동력에 대한 수요는 증가하고 있으나 공급은 과거보다 훨씬 줄어들었다. 특히 건강한 에이즈감염인들의 경우 건강에 이상이 없기 때문에 노동에 대한 욕구는 크지만 그들이 처한 상황 특성상 노동의 기회는 제대로 주어지지 않고 있다.

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.

Over the past 30 years, Korea experienced demographic transition which typically substitutes quality(education) for quantity(number) of population. This paper decomposed labor supply into quantity and quality aspects and estimated the respective employment elasticities of economic growth in the past. Then, based on the assumptions about the future population (by age, sex and education) and labor force participation rates, the future labor supply(both quantity and quality) is projected and growth potential of the Korean economy is evaluated. The result shows that labor supply in Korea is relying gradually more on the qualitative rather than the quantitative aspect but since the increase in the former will not fully compensate the decrease in the latter, the potential growth rate of the Korean economy will be substantially reduced in the futrue.

This study examined the relationship between income and the value of leisure to develop a more accurate model of the labor market without necessarily losing the primary merit of the received model. Moreover, with an improved understanding of the labor market dynamics, it can be seen that progressive era labor market legislation, which was designed to mitigate the effects of the bargaining power inequality in low wage labor markets, was in fact based on sensible economic foundations. These low-wage dynamics present an example of a positive feedback system or "vicious circle" at work in the economy. The market dynamics of the low wage sector push the wage away from the range that is consistent with a self-regulating market.

This study examines the impact of Long-Term Care Insurance(LTCI) on family caregivers(especially focused on female household members) labor supply in South Korea. When public care and informal care are substitutes, LTCI will change allocation of time of family caregivers to spend more time to paid work. The impact of LTCI on labor supply depends on each country's institutional level of public care services. If public care can not substitute for informal care, labor supply of family caregivers will not rise significantly. The conclusions of vigorous empirical study from western countries' are incompatible and problem of endogeneity in terms of methodology has been raised consistently. The dataset of this study are used the third and ninth waves of Korea Welfare Panel. As a result, the introduction of LTCI had no effect on labor supply of household members. Robust findings suggest the positive effects of caregiving on labor market outcomes in simple comparison t-test, but not in fixed-effect regression. Compared with western countries, South Korea's public care services can be interpreted as a supplement to only part that remained at the level does not substitute informal care. These findings may suggest that if LTCI become much more prevalent in the future, senior citizens and family members will be able to choose the LTCI arrangement that best suits their needs.
