We found following evidences from our empirical analysis with the Workplace Panel Survey data of the Korea Labor Institute with reference to 'discord hypothesis' which insists that employee participatory high performance work practices would strengthen not only an enterprise focus in labor-management relations but also the enterprise unionism in the labor union system or collective bargaining structures, so they would probably come into conflict with the superenterprise-oriented industrial solidarity spirit in labor unionism. First, even though there are significant positive management performance effects of high performance work practices, especially in case of mining and manufacturing industries, the positive performance effects of employee participatory work practices such as job rotation ratio of workers and 6-sigma activities were much strengthened relatively in case of non-unionized establishments. Second, the superenterprise-oriented collective bargaining system is also found to give very strong and statistically significant negative performance effects to the introduction and implementation of work teams and performance-related payment systems such as profit sharing, group incentive pay system and so on. Although there are some careful reservations in interpreting the results of our analysis because of data insufficiency, they may have important implications that the industrial labor unionism or the superenterprise-oriented collective bargaining practices exercise the bargaining power to make individual firms be negative or feel it nearly impossible to introduce the employee participatory work practices which can be very favorable to improving those management performance.

This study analyzed the factors related to labor market transition of job injured workers. The Workers' Compensation Insurance Panel data ver.1, which that was surveyed by the Korean Workers' Compensation & Welfare Service in 2013, was used. Four key findings were made: first, the economically inactive populations are 7.2% and unemployed is 22.3% of occupational accident workers who finished the treatment period; second, 31.5% of laborers who returned to a new workplace went into another type of occupation; third, the results showed that socio-demographic factors, such as gender, age and education years, injury-related factors, such as the treatment period and work limitation, and workplace factors, such as company size and employment status, were associated with the return to work; and fourth, a relatively higher proportion of people who has received occupational training could not return to work and the disability grade was not associated with the return to work. These results suggest that policy makers need to understand the characteristics of labor market transition of job injured workers and develop efficient intervention programs based on the transitional labor market.

In this paper, we use panel dataset from Korean linked worker-firm to analyse the effects of the workforce age structure on the productivity or labor costs. We measure 'labor productivity' as added value per capita, 'cost of labor' as labor cost per capita and estimate a dynamic panel model to study the effects of the workforce age structure on the productivity or labor costs. Empirical analysis results show that the workforce age structure is positively related to productivity and labor costs, but only up to the aged of 35-39. That is, we find that an increase in the proportion of younger workers or elder workers rather than the aged 35-39 has a negative effect on productivity and labor cost. In particular, the difference between the estimation coefficient of productivity and labor cost when the share of workers aged 50 or older is increased instead of the aged 35-39 is higher than the difference between the estimation coefficient of productivity and labor cost when the share of workers aged 30 or younger is increased instead of the aged 35-39. Our results exhibit that it is reasonable for firms to worry about declining productivity of elderly workers, whereas firms already used older workers efficiently, such as by adjusting their labor costs.

This study examines the relationship between flexible work and workers' work-life balance using data from the 23rd Korean Labor and Income Panel Study, with a focus on the impact of working from home (WFH) during the COVID-19 pandemic. As a result of the analysis, WFH was found to have a positive effect on the happiness of workers, satisfaction with family relationships, job satisfaction, organizational commitment, and job satisfaction related to job security for women. In addition, we looked at the changes in time use of WFH workers and non-WFH workers before and after COVID-19, with a particular focus on aspects such as time spent sleeping and on self-development, childcare, housework, exercise, and social gatherings. Compared to non-WFH workers, WFH workers increased the time spent on housework and childcare after COVID-19, with this trend more pronounced among women. The results of this study suggest that the effect of utilizing WFH may be halved for workers who have to take care of children and work at the same time, and that this effect may be greater for women. Therefore, it is necessary to strengthen social support measures so that WFH workers who face a work-life conflict due to childcare can maintain work productivity and realize a work-life balance, and to ensure that the flexible work arrangement should not be a medium that reinforces traditional gender roles. Active policy efforts will be required to make sure this happens.

Public investment in education has been justified by assumed positive externalities of education. Using the 1995 10% Population and Housing Census and 1998 Korean Labor and Income Panel Study, this study first examines the distribution of human capital across Korean cities and industries, and second, investigates the sizes of external economies of education by exploring how the average schooling of workers in cities and industries affect an individual worker's hourly wage. Generally, the average schooling of workers in the capital region cities is much higher than in other cities and the average schooling of workers in high tech industries is much higher than in other industries. As the average years of schooling in a city increases by one year, workers with the same personal and job characteristics such as sex, education, experience, occupation, and firm size, earn about 3% more. Also as the average years of schooling of workers in an industry increases by one year, the workers with the same personal and job characteristics earns about 5~7% more.

The panel survey is need to have a more concern about a response due to a secession and non-response of a sample. And generally a population is not fixed and continuously changed. Thus, the rotation sample design can be used by the method replacing the panel research. This paper is the study of comparison to equal weight method, Duncan weight, Design weight method, weight share method in rotation sample design. More specifically, this paper compared variance estimators about the existing each method for the efficiency comparison, and to compare the precision using the relative efficiency gain by the Coefficient Variance(CV) after getting the design weight from the actual data.

Using the data from the KLIPS, this study categorizes unemployed women into the four mutually exclusive groups according to the two criteria (whether to have intention to work and the comparison of reservation and market wages), and investigates factors affecting the status of the unemployment of women. Heckman's sample selection regression and multinomial logit are applied for the estimation. The major results are: the proportion of unemployed women who do not have intension to work or whose reservation wages are greater than expected market wages is about 50%, and the proportion of unemployed women who have intension to work or whose reservation wages are less than expected market wages is about 50%; second, human capital, burden of child raising and household production, household economic status, the variables related to work experience are found to be the factors affecting unemployment status of women.

The high unemployment rate is one of the major problems in most countries nowadays. Hence, the demand for small area labor statistics has rapidly increased over the past few years. However, since sample surveys for producing official statistics are mainly designed for large areas, it is difficult to produce reliable statistics at the small area level due to small sample sizes. Most of existing studies about the small area estimation are related with the estimation of parameters based on cross-sectional data. By the way, since many official statistics are repeatedly collected at a regular interval of time, for instance, monthly, quarterly, or yearly, we need an alternative model which can handle this type of panel data. In this paper, we derive the generalized kernel estimating equation which can model time-dependency among response variables and handle repeated measurement or panel data. We compare the proposed estimating equation with the generalized linear model and the generalized estimating equation through simulation, and apply it to estimating the unemployment rates of 25 areas in Gyeongsangnam-do and Ulsan for 2005.

This study uses the youth panel survey (YP2007 2th ~ 9th) data of the Korea Employment Information Service to examine the phenomenon of subjective mismatch arising from the youth labor market and analyzed the determinants and wage effects of subjective mismatch. Overall, the analysis showed that the over-education and over-technology of both educational background and technical skill level in the Miss Match significantly decreased, while the lack of education and technology increased rather gradually. Next, the analysis of the determinants of downward employment(Excess of education and technology) showed that males were less likely to be downwardly employed(Excess of education and technology) than females, and in the status of workers, the probability of downward employment of regular and non-wage workers was lower than that of temporary/daily workers. Finally, as a result of estimating the wage effect of the mismatch based on the pooled OLS model and the Panel Fixed Effect model, the mismatch which has the greatest effect on the wage was found to be excessive education, and it has been estimated that youth employees who are over-educated have an average 6.7% lower wages than those who are not. After controlling for the unobserved individual characteristics, they were found to receive a lower wage of 3.2%, and it is estimated that 2.9% for the technical excess mismatch and 2.3% for the major mismatch receive lower wages than the reference group.
