This study analyzes the initial effect of meister high school policy on labor market by DID based on the fact that most of the meister high schools that had its first graduates in 2013 were not newly established but assigned by government. We estimated employment and real hourly wages as quantitative measures and intent to remain in labor market as qualitative one. The results shows that, the meister high school policy increased the employment rate but didn't do real hourly wages and intent to remain. Therefore, meister high school policy can be assessed to be successful in short-term only in quantitative aspects. The study has its contribution as the first study of estimating the net effect of the policy.

This paper estimates the impacts of introducing the 40 hour work week standard in South Korea on actual working hours, wages and employment. We exploit variation in timing of implementing the 40 hour work week standard across industries and establishment size and estimate the causal effects by a triple difference model. Our results show that the 40 hour work week standard decreased actual working hours by about 43 minutes while it increased hourly wage rate by 6.6%. The probability of new hires decreased by about 2.3% points.

This paper attempts to verify that the economic gap between the workers in (large) firms with unions and those in (small and medium size) firms with no unions has recently been widened rapidly. A comparison of the wages of the workers belonging to the business establishments with and without trade union shows that the union premium has increased very sharply since 1997, after a relatively long periods with little changes. Also found is that union sector has witnessed a sharper decline in the share of the new entrants among workers as well as a faster increase of the average tenure of workers. These all indicate that the trade unions have forced a market equilibrium to move farther away from the competitive equilibrium in recent years.

While they compare the growth rate of wage with that of average labor productivity, we compare it with the growth rate of marginal labor productivity. After estimating the elasticity of substitution and technology level, we estimate the marginal labor productivity. Wages and marginal labor productivities are similar over 1963-2000. However, while wages come short of marginal labor productivities over 1963-1986, they exceed marginal labor productivities over 1987-2000. Although the growth rate of wage is not so different from that of marginal labor productivity, it can be disparate from that of average labor productivity. Therefore the former exceeding the latter does not mean the excessive wage growth off the labor demand curve.

Extension of mandatory retirement age (MRA) differs from other labor supply increases in that it induces a change in the incentive to save for retirement. A simple general equilibrium model indicates that extension of MRA can lead to a decrease in life-time income and social welfare as it excessively discourages domestic savings and thus capital accumulation. However, in an open economy where capital inflow allows capital input in production to remain constant despite lower domestic capital stock, extension of MRA likely increases worker welfare. In such case, extension of MRA can contribute to expansion of hiring demands through lowering wages or mitigating upward pressures on wages.

This is an empirical study in Korea on the effects of the minimum wage. Based on the survey data of security workers of 132 apartment in Seoul metro area, the study finds that the introduction of minimum wage in this sector in 2007 raised wage by 10.9%, reduced employment and work hours by 3.5-4.1% and 13.5% respectively. This implies a short run wage elasticity of employment of -0.312 but much higher elasticity of work hours of -1.68.

Following two pioneering works, Medoff and Abraham(QJE 1980; JHR 1981) and Flabbi and Ichino(LE 2001) which use performance rating of personnel data as individual worker's productivity, this study replicates their analysis using a Korean large firm's personnel data(2000, male white collar workers). According to their methods through Mincerian earnings function, and multinomial logit model that links the distribution of wages and performance ratings, we find that seniority wages appeare continuously even if individual worker's productivity is controlled. Therefore we conclude that incentive or deferred compensation theory is more suitable than human capital theory.

We collected survey data from those who have Vocational Training Teachers' Qualification to investigate the workplace characteristics and job satisfaction of the qualified people. Also, this study analyzed the determinants of the Vocational Training Teachers' monthly wages. Statistically Significant variables were male, age, graduated from graduate school, work duration, total work hours, regular workers, and levels of the certification. Since previous studies argued that the levels of the certification did not have effect on the wage, result of this study suggested that the further study and discussions on the effect of the levels of the certification was needed.

This study is performed for the investigation of management of personnel, wages, welfare, communication, labor, safety, treatment improvement according to assigned working places(primary, middle and high school). This study is based on the final analysis summarized on the 285 questionnaire answered by employee for school foodservice in Buchon city after distributing total 500 questionnaire. The conclusion of this analysis of study is as following. This report says the reason of this mind is caused by hard work. This investigation says they feel to be compensated with low wages on the contrary their hard working and this caused them to demoralize and increase to give up their jobs. The long tenn vacation like childcare vacation is newly established by present improvement of working condition but this improvement action is ineffective. Many of them are feeling to a fatigue and ill health and the condition of occupational disease as hard work. The present improvement of irregular employee treatment like above cases is not effective. So the rewards and payment shall be considered according to their hard work and the working condition must be improved practically for the settlement of their job without leaving.

This paper investigates the impact of the effective minimum wage, defined as the log difference between the minimum and the median wages, on wage inequalities in the OECD countries. Unlike the previous studies that focus on single countries in which the minimum wage has no cross-sectional variation and rely instead on within-country variations of wage distribution across regions or socio-economic characteristics, we use a country panel that allows for both cross-sectional and time-series variations in minimum wage. We also control for more factors than in the previous studies whose absence may cause endogeneity. Our results confirm the previous findings that increases in minimum wage alleviate the wage inequality at the lower tail of the wage distribution, while having little effect at the upper tail. The estimated effect is larger for women than for men, which is consistent with the fact that the share of workers who are directly affected by the changes in minimum wage is bigger among women than men. An application of the IVs of Autor, Manning and Smith (2016) supports the robustness of our findings.
