This study first attempted to measure the job instability of Korean labor market by exploiting the data sets of 1998 and 1999 Korean Labor Panels. In order to compare the degrees of job instability of Korea with the one of U.S., we followed the same empirical methods used by Jaeger and Stevens(1999), Neumark et al.(1999), Bemhardt et al.(1999) recently published in the Journal of Labor Economics (vol. 17). Our empirical results suggest that the job retention rate of the Korean labor market during the IMF economic crisis was decreased to the level that the U.S. labor market has never experienced during the past two decades. One noticeable point regarding our estimated four year retention rate is that it takes a form of plateau peaked around 9 and 15 tenure year, which is in sharp contrast with the four year retention rate of u.S. showing a monotonically decreasing tendency over tenure periods. The comparison of 2-year retention rates before and after the economic crisis suggests that job stabilities has been conspicuously aggravated especially for cohorts of long tenure, irregular job, old age, service and sales jobs.

This study compares and analyzes precarious labor market in Korea and Japan in terms of gender and occupational class. Previous studies have analyzed precarious labor limited to the level of employment type such as non-standard workers. This study reconceptualizes precarious labor in terms of the combination of employment relations and income level. In addition. we analyzed whether there are differences in the characteristics of precarious labor between Korea and Japan. In order to analyze the labor market precariousness in Korea. we used data from the 17th Korea Labor Panel Survey (2014) and for Japan. we used the 9th (2012) data from the Keio Household Panel Survey. As a result. we could confirm the feminization of labor market precariousness and horizontal division by occupation in both Korea and Japan. Also. ordered logistic regression analysis showed that the more women. and those in their 60s or older. the less skilled service workers. or the manufacturing workers are likely to face labor market instability in both Korea and Japan. The results of this analysis reflect the fact that Korea and Japan have experienced similar changes in the labor market structure with institutionalized employment protection system based on male workers.

The objective of this study is to examine the trend of real earnings for TANF leavers. Using administrative data in Wisconsin, this study tracks the 1998 TANF leavers over 7 years. Based on the cyclicality of real wage hypothesis, this study finds: First, although the average real quarterly earnings of TANF leavers have remained stable since their exits, there are substantial labor mobility among TANF leavers. Second, the panel data analysis shows that the real earnings of TANF leavers are significantly associated with local labor market conditions, which supports the hypothesis on the cyclicality of real wages. This study has policy implications that labor market conditions matter for the economic well-being of TANF leavers and the labor demand policies are needed for the economic security of TANF leavers after the exit.

Using panel data from the Korean Labor and Income Panel Study(KLlPS), we examine the wage differentials between standard and Don-standard workers. To control for unobserved individual heterogeneities, we estimate the fixed effect models. Our results show that the OLS estimates are upwardly biased. We also find that labor unions and firm size are important determinants of the wage differentials.

This paper criticizes the arguments for the high and rigid reservation wages as main cause of the youth joblessness. First, using longitudinal aspect of the Korea Labor and Income Panel Study, I found that there exists declining reservation wage for the young who make the transition from unemployed to employment. Second, the average duration of school-to-work transition in Korea is relatively low compared to that of other countries. Moreover the duration between leaving school and staring the first job has not significantly negative effect on adult labor market outcomes, but the quality of first job and unstable job experiences have serious negative effects on working career. These findings show that the high youth joblessness is due to both decent job deficit and labor market segmentation.

This paper empirically tests the theory that labor demand elasticity of unionized firms would be smaller than that of nonunionized firms, using the Korean firms' panel data for 1990-2009. The major findings are the following: First, the estimates of labor demand elasticity of unionized firms are in the range of 0.34-0.49, less than a half of those of nonunionized firms, hence supporting the theory. Second, the unionized firms are more rigid in dynamic adjustment of employment than nonunionized firms. Finally, there are no significant differences between unionized and nonunionized firms in the elasticity of substitution.

This study stemmed from the notion that effects of wage peak system were investigated exclusively on management efficiency from the perspective of workplace. As a way to overcome the limitation of previous studies, This study examined the effects of wage peak system on age integration of senior workers. Quantitative analyses with data from workplace panel survey were executed. Results revealed that percent of workers aged 50 and over was significantly higher in work places that implemented wag peak system than that of those did not. Also Average year of employment for full time workers was higher in work places that implemented wag peak system than that of those did not, suggesting that wage peak system was related to labor market integration of aged workers in some ways.

Using the Korea Labor and Income Panel Study(KLIPS), this study analyzes the effects of profit sharing on employer-provided training. The estimation results of the fixed effect model that controls for endogeneity show that the workers of profit-sharing firms have a 6.7%-6.8%p higher probability of receiving employer-provided training than the workers of firms without profit sharing. They also show that the workers of profit-sharing firms have a 3.3%p higher likelihood of having employer-provided OJT than their counterparts. The impacts of profit-sharing on employer-provided training appear consistently regardless of the estimation models and in the subsamples. These findings support the hypothesis that profit-sharing promotes employer-provided training.

This study is to identify the factors deterring or precipitating the exit from welfare recipiency to labor market in the Korean social assistance program. The results from the empirical analyses of the Korea Welfare Panel Study(KOWEPS) show that the duration dependency is not due to increasing welfare dependency with duration, but to the fact that longer stayers have many vulnerable conditions to escape from poverty. Particularly, the main factors determining the transition from recipiency to labor market are not individual or household characteristics such as human or social capital. Those having adolescents of secondary education in their households or participating in some effective labor market program such as job placement service tend to have significant effects on the exit rates from recipiency. That means that the institution-related factors such as the education and health supports combined with benefits and the effective labor market programs are important in the translation from recipiency to labor market of working-age recipients in the Korean social assistance scheme.

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.
