This study intends to analyze the trend of employment rate of men aged 55~64 in 15 OECD countries from 1980 to 2005. Furthermore, this study means to examine the determinants of men aged 55~64 in 15 OECD countries to support the labor force participation among them. The analysis is based on the data of OECD, ILO and LIS. The analysis method is Arellano and Bond(1981)'s difference GMM which used instrumental variables by dynamic panel model which estimates state dependency of labor market participation and individual panel's heterogeneity. The main results from this analysis are summarized in three points. First, the employment rates of men aged 55~64 had decreased until the middle of the 1990s, while that has been increasing since 1995. Second, the sate dependency strongly worked in the employment rates of 55~64 men and positive period effect was observed for 1980~2005. This study cannot find the pull effect of public pension, while labor market push effect have negatively affected. Third, temporary work rates had contributed to increase the employment rate of men aged 55~64 for 1996~2005. The poverty has become the mechanism of the labor.

It is expected that labor mobility and inter-industry labor turnover would rise due to the rapid changes in the industrial structure and legal institutions of layoffs after the 1997 economic crisis in Korea. One aspect of economic costs of labor mobility is demise of accumulated skills of workers. Workers' skills could be decomposed into three parts, general skills, firm-specific skills, and industry-specific skills. Using data from the panal data of Korea Labor Institute(KLIPS), I show that the net return to seniority is markedly reduced once industry-experience are controlled for. The returns to industry-specific experience are relatively high. Particularly, the experience in one-digit industry is more important for the white-collar workers, while the experience in three-digit industry is also important for the blue-collar workers. Therefore, it seems that the economic cost of labor mobility would be diverse between the skills and between the working classes.

This paper empirically analyses the effect of labor union on firm's profit rate in Korea. For this purpose a panel data set has been constructed for the period of 1990-2009 using "TS2000", and the data set has been subdivided into two: one is the 'non-variant group' in which firm's union status has not changed, and the other is 'variant group' in which firm's union status has changed from non-union to union during the sample period. It has been found that for 'non-variant group' there is no significant union effect on profit rate. However, for 'variant group' the presence of union has been found to decrease firm' profit rate in terms of return on equity.

This study analyzed the effects of labor aging on labor productivity using panel statistics of 16 local governments from 1995 to 2017. The aging of the labor force, defined as the proportion of workers aged 60 or older in total employment, in the results of the panel regression analysis considering regional fixed effects and various adjustment variables, has a very consistent and significant negative effect on labor productivity. For every 1% increase in aging, labor productivity decreases by about 0.14 ~ 0.20%. In addition, the per capita capital stock and human capital considered as adjustment variables contributed to the increase of labor productivity, and the unemployment rate, which is a proxy variable of the economic fluctuation, has a significant negative effect on labor productivity as expected. The coefficient of the industrial structure, which represents the share of the service industry in the whole industry, was positive, but is not significant. The results of this study suggest that the design and construction of economic and educational policies that can maintain and expand human capital are necessary to curb the reduction in labor productivity expected by the aging workforce.

This paper examines the impact of a dual labor market structure on labor productivity using unbalanced panel data from 29 OECD member countries between 1990 and 2015. By applying a variety of regression models on the panel data (e.g., a pooled regression, a fixed effects model and a GMM), we explore how changes in worker-type composition among temporary, permanent and self-employed workers contribute to productivity growth. While it appears that our results differ slightly, depending on the econometric models, overall an increase in the share of permanent workers leads to a relatively higher increase in productivity growth. On the other hand, it is also seen that the effects of the share of temporary workers on labor productivity are considerably lower than that of permanent and self-employed workers. To sum it up, our findings indicate that an increase in temporary workers could have an adverse effect on labor productivity.

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.

Longitudinal analysis of individual wage data received from the Korea Labor and Income Panel Survey (KLIPS) for the 1998-2012 period reveals that nominal wage reductions are prevailing among job stayers. It is also found that the probability of nominal wage cut is higher in the period of lower inflation or higher unemployment, and affected by various individual or group characteristics. Additional analysis of two establishment-based average wage series and the KLIPS shows that real wages are substantially procyclical, which is attributed to the strong procyclicality of nominal wages rather than countercyclicality of inflation. Current findings defy wage-rigidity-based explanations of unemployment fluctuations or models that predict wage rigidity, inlcluding segmented labor market hypotheses.

In this article, I were trying to analyze the listed manufacturing companies' trend of productivity and the corporate education & training effect after the financial crisis. According to the analysis, the listed manufacturing companies have decreased their productivity since financial crisis, and from such declining trend. jobless growth and a growth without physical and human capital investment has been observed. Furthermore, there is no efficient labor force coordination within the manufacturing industry; In order to analyze the effect of education & training investment on productivity more deeply, I have practiced the dynamic panel data analysis from constructing the micro panel data which consists of company level information 1997~2008. According to the consequences, dynamic panel data analysis solved the problem of the overestimating education & training effect fairly well.

This study aims at exploring the change of the total fertility rate(TFR) in regional level and analysing what different effects the local labor market and housing market have on the change of TFR. Previous studies have emphasized that the job and housing issues of the youth are structural factors on the decline of TFR. However, considering that youth problem is variant in local level, the relationship of job and housing issues with TFR could be different in local level. This study analyses what effects the situation of local labor market and housing market have on the TFR from 2012 to 2018 in regional level. The result is that the employment and housing factors have different effects on capital areas and non-capital areas. While the high cost of housing has negative effects on TFR in capital areas, it has rather positive effects in non-capital areas. However, labor market variables have statistically insignificant effects on TFR.

This paper estimates the intergenerational income mobility of Korea by applying the new errors-in-variable correction methods to recent waves of the Korea Labor and Income Panel Study. The intergenerational income elasticity estimates ranged from 0.24 to 0.34 show a substantial intergenerational income association in Korea and an upward trend over time.
