This paper analyzes the changes in wage inequality and its contributing factors since the mid-2000s. Although trends vary by data and wage indices, the Gini coefficient of the total wage of all workers shows an increasing trend due to the part-time increase of less than 35 hours per week, while the wage Gini coefficient of hourly wages and the total wage Gini coefficient of full-time workers showed a declining trend. Part-time increases have increased inequality based on total wages, but part-time hourly wage increases can be considered to have reduced hourly wage inequality. Therefore, as a result of decomposing the factor of Gini coefficient reduction only for full-time workers, factors that contributed absolutely to inequality reduction were variables such as job tenure, career, and occupation, and employment type variable has little effects, and the establishment size variable deepens inequality. The variables such as industry, age, and education did not contribute significantly to the inequality change. This is attributed to the decline in wage premiums for job tenure and management and professional jobs and the increase in wage premiums for large-scale businesses.

The purpose of this paper is to analyse wage differentials between non-regular and regular works. Data from EAPS(Economically Active Population Survey) 2005 show that the monthly wage level of non-regular worker is only 63% of regular worker and thus there exist 37% wage differentials. However, these wage differentials do not control for hours of work, the amount of human capital, job characteristics, and other individual characteristics affecting wages. If these variables are added to the hourly wage regression equation, the wage gap between non-regular and regular workers drastically decreases to 2.2%. Furthermore, decomposition of the wage differentials by Oaxaca method shows that productivity difference between non-regular and regular workers explains up to 91% of the wage gap. This implies that the magnitude of wage discrimination against non-regular workers is at most 0.2% of hourly wage of regular workers. To control for unobserved individual heterogeneities more accurately, we also construct panel data and estimate wage differentials. The results from the panel data approach show that there is no difference in the hourly wages between non-regular and regular workers. In some specifications, the wage rate of non-regular worker is rather higher than that of regular worker. These results are consistent with economic theory. Other things being equal, workers with unstable employment may require higher wages to compensate their unstability. Firms are willing to pay higher wages if they can get more flexibility from non-regular employment. Empirical results in this paper cast doubt on the view that there is wage discrimination against non-regular workers in the labor market. Public policies should be targeted for disadvantaged groups among non-regular workers, not for non-regular workers in general.

This study analyze Family gaps(the wage gap between mothers and non-mothers) across the wages distribution in Korea using 2008 Korean Labor and Income Panel Study. Analysis models include Heckman's two stage estimation to control women's labor participation selection and Quantile regression method to examine the effects of children at different points of the wage distribution. The result indicates that first, comparing non-mothers, mothers with one child suffer statistically significant hourly wage losses at 25th, 50th, and 75th distribution, however not significant effects are found at lowest(10th) and highest(90th) distribution. Second, comparing non-mothers, mothers with two more children suffer statistically significant hourly wage losses at all distribution. Family gap differs across the wage distribution and highest family gaps are found at 25th distribution. With these results, the author suggests universal family policies to support mothers' labor participation and the reconciliation of work and family.

The social impact of observing others' charitable donations remains underexplored, with few studies examining the influence of donors' social class. Across three experiments, we investigated how the donor social class-donation type interaction influences the observers' perceived sacrificial costs or desire for a moral self-identity, which consequently affects their willingness to donate. The participants perceived higher costs when lower-class donors made monetary donations, but for time donations, they saw no difference in sacrificial costs by donor social class. Moreover, when the hourly wage was emphasized, the participants felt an increased desire for a moral self-identity from higher-class donors' monetary donations and became more willing to donate their money. These findings highlight the importance of considering both the donor social class and donation type when designing donation campaigns, and offer valuable insights for enhancing overall donation amounts.

This study, using Korean Time Use Survey 1999, analyzes how opportunity costs of maternal time affects the ways in which mothers allocate their time to market work/housework/child care/leisure. Opportunity costs include two kinds: hourly child care costs and log hourly wage rates. Results show that a unit increase in child care costs reduces market work but increases housework, child care, and leisure. The effects of log wage rates are opposite those of child care costs. The result that a unit increase in the log wage rates decreases child care lime is not consistent with a previous study for the United Stales. These results differed by mother's educational attainments. This study suggests that policy-makers should pay careful attention to the effects of various types of mother's opportunity costs on non-market time in promoting maternal employment.

Background: The purpose of this study is to analyze the effect of the income support allowance policy for the care workers on wage level. Methods: The analysis data was constructed using database (DB) of long-term care institution, DB of long-term care personnel status, and DB of health insurance qualification and contribution possessed by National Health Insurance Services. We analyzed the wage status of care workers 2009 to 2016 through basic analysis. We used the difference-in-difference analysis method for the workers who worked in the same institution from 2012 to 2013, The effects of the income allowance policy on wage increase were analyzed. Results: As a result of the net effect of the income support allowance policy, the monthly average wage of the care worker increased by 25,676 won and the hourly wage increased by 478 won. As a result of the analysis, it can be confirmed that the income support allowance policy has achieved some of the goals of raising the wage level of the care workers, and the effect of raising wages for other occupations in the long-term care business can be confirmed. Conclusion: The low wage problem of long-term care workers such as care workers is not the only problem in Korea. In other countries, there are various wage support policies for employees. In particular, it is necessary to refer to the improvement in the treatment of care workers in Japan and wage pass-through in the United States. In addition to wages, there is a need to promote policies to provide employment motivation through efforts to improve their social status and improve their job status and career development for employees in long-term care facilities.

Employing bunching estimators of Cengiz et al. (2019) for data from the "Economically Active Population Survey," this paper estimates the effect of minimum wage increases on the volume of waged employment for the period 2009-2019. A bunching estimator, which exploits yearly changes in the hourly wage distribution due to the minimum wage hike, can be easily applied to the Korean labor market, which adopts the yearly single national minimum wage. The estimation results suggest that an increase in the annual minimum wage during the period from 2009 to 2019 had a negative effect on the volume of waged employment. A 10% increase in the (real) minimum wage leads to a 1.42~1.74% decrease in the volume of waged employment. Disemployment effects of minimum wage hikes are greater in the sector with a higher proportion of minimum wage workers. It is necessary to carefully consider disemployment effects in determining the level of the minimum wage.

Background: In this study, wage status and wage determinants of care workers were analyzed. Methods: The analysis used database (DB) of long-term care institutions, DB of long-term care institutions, DB of long-term care workers, DB of health insurance qualification, and contribution possessed by National Health Insurance Services. We analyzed the wage status of the care workers from 2009 to 2016 through basic analysis and estimated the factors affecting the wage of the long-term care facilities' care workers using pooled ordinary least squares. Results: The monthly average wage of care workers was raised from Korean won (KRW) 1.37 million in 2009 to KRW 1.52 million in 2016, and the working hours were shortened by 20 hours from 207 hours to 187 hours. Hourly wages increased by KRW 1,329 from KRW 6,831 in 2009 to KRW 8,160 in 2016. The average monthly wage of care workers was affected by gender, age, years of employment, monthly working hours, establishment type, city size, institutional size, the grade of the institution, and management status. In particular, the wage level of the care workers was high when the larger the size of the institution, the better the management status (fill rate), the establishment type is "government and local government" and "corporation," the institutional rating is high, and the facility manager has the first grade of the social worker license. Conclusion: The government should consider aggressive policies to improve the treatment of care workers as well as the quality of long-term care services so that there will be more long-term care facilities that are guaranteed social publicity above a certain level.

This study aimed at empirically analysing the double discrimination on the elderly with disabilities due to both age and disabilities in the labor market. To achieve this research goal, real employment probabilities and hourly wages of the elderly disabled(below "ED") were compared with those of the young disabled(below "YD") and those of the elderly non-disabled(below "END") to calculate empirical differentials between ED's and YD's, and ED's and END's. The differential decompositions between groups were applied by the Oaxaca(1973). The study results were as followings. First, the real gaps of the employment probabilities between ED and YD only appeared at the regular jobs and the gaps due to the characteristics between ED and YD were bigger than those due to the age discrimination. Second, on the contrary, the gaps of the hourly wages were caused by age discrimination more than characteristics between YD and ED. Third, it was not true that the elderly with disabilities take double discriminations in the labor market. It is therefore required to give the additional incentives to ED workers with government subsidies of employment promotion for the disabled provided. Second, it is proposed that the integrations the employment policies for the disabled with those for the aged because the disability as dependent valuable didn't have statistically significant effects on the employment probabilities and the hourly wage levels.

This paper examines why older wage workers leave their jobs and what determine the hazard of retirement. Major results are as follows. First, aged workers leaving their jobs because of formal mandatory retirement are relatively few in number and largely males employed in large establishments. Second, a higher hourly wage is associated with a greater retirement hazard, especially among male employees of large firms. Third, informal mandatory retirement puts a strong pressure towards retirement among older female workers. Fourth, poor health is the primary reason for retirement among older workers, especially for females and small-firm employees. Finally, reasonable hours and greater flexibility of work tend to lower retirement hazard. We discuss some implications of the results for old-age labor market policies.
