This study investigated the latent groups depending on married working women's work-family spillover. The effects of factors that determine mental health subgroups and differences were also analyzed. Mixture modeling was applied to the Korean Longitudinal Survey of Women & Families to achieve the research objectives. The major findings of this study were as follows. First, there were four subgroups that could be defined according to the work-family spillover: mid-level spillover group (mid-positive and mid-negative spillover group), high-level spillover group (high-positive and high-negative spillover group), low-level spillover group (low-positive and low-negative spillover group), and high-negative and low-positive spillover group. Second, the results of mixture regression analysis to test the effect of eco-system variables showed that age, academic background, non-traditional family value, number of children, work hours, wage income, and availability of the maternity leave were significant determinants of the latent groups. The probability of classifying in the high-negative and low-positive spillover group increased when women showed a lower academic background and wage income, higher number of children and older age, and longer work hours than others. Third, the high-level spillover group, and the high-level spillover group showed the lowest stress and the lowest depression; however, the low-level spillover group reported the highest stress and the highest depression. Implications, limitations, and future directions were discussed based on the results.

The purpose of this study was to investigate how work-family spillover differed by employment status of married women and to identify factors related to the differences. This study drew a sample of 332 self-employers, 181 unpaid family workers, and 1,053 wage workers from the 2014 Korean Longitudinal Survey of Women and Families. It was found that negative work-family spillover did not differ by employment status of married women. However, positive work-family spillover was found the lowest in family workers. The regression analysis showed that the difference remained after controlling socio-demographic characteristics, average working hours, and the number of days off per week. The factors related to negative spillover were age, the presence of young children, working hours, and the number of days off. Findings from this study suggest that family workers are most disadvantaged in terms of work-family spillover. Yet there is no policy developed for them. Family policy needs to take them into account in planning and implementing services.

This study analyzes the effect of a minimum wage on the wage compression within Korean establishments. The results are as follows. Firstly, increases of a ratio of workers who get minimum wage within establishments have a effect to compress the wage distribution within establishments. Secondly, the establishment average wages get lower as their minimum wage ratios get larger. In this situation, high wage group's wages fall deeply than low wage group's these. Thirdly, the relative wages of high wage group to low wage group tend to be small as their minimum wage ratios get larger. To conclude, a increase of minimum wage has a effect to raise low wage workers' wages directly, and to reduce high wage workers' wages or increase rates indirectly. And the wage distributions are compressed as a result. So government's policy to increase minimum wage will have a result in reducing wage inequality.

This paper consists of two parts. The first part introduces a simple endogenous growth model. It is based on Romer(1990), but extends the original model by incorporating individual workers skill heterogeneity. Based on the heterogeneity, the model has a labor allocation mechanism between skilled (research) and unskilled (production) sectors. Different from Romer(1990), the labor allocation is determined by both demand and supply conditions of the economy. The endogenous growth model presented in this paper shows how the shape of the distribution of human capital affects on the labor allocation, hence on the employment structure, wage profile and economic growth. The model can be extended to an open economy. With the heterogeneity, the extended model explains distributional effect as well as growth effect of the economic openness. The second part provides empirical evidence in support of the extension part of the model presented in the first part. Based on the endogenous growth framework as proposed by Romer(1990) and Rivera-Batiz and Romer(1991), the model explains how economic openness affects labor allocation between skilled and unskilled sectors. According to the model, economic openness can affect labor allocation through two channels; knowledge spillover and specialization. First, the openness promotes knowledge spillover and hence increases the productivity of workers in the skilled sectors. This makes the economy employs more workers in the skilled sector. On the other hand, the openness causes global specialization which leads more employment in the skilled sector for the developed countries but at the same time, leads less employment in the skilled sector for the developing countries since the developing countries have comparative advantages in the unskilled sector. The empirical results obtained using cross country panel data in this paper support these two effects of knowledge spillover and specialization.

Using data sets from the Korean Labour and Income Panel Study (KLIPS) for the period 2003-2015, this study shows that wages of nonunion workers are positively related to the percentage of unionized workers in the same geographic region. A 10 percentage point increase in a region's union density is associated with a 4.9 percent increase in the region's average wage of nonunion workers. It is also shown that this positive spillover effect is observed for various subgroups of nonunion workers, including women, youth, low-educated workers, small firm employees, and those employed under nonstandard work arrangements. In contrast, the average wage of union workers is found to respond insignificantly to changes in a region's union density.
