This paper estimates the effect of the minimum wage increment on employment and work-hour of new workers in Korea using the data from the Survey on Labor Conditions by Type of Employment (SLCTE) from 2008 to 2017. We construct worker groups by sex, age, and education to mitigate endogeneity problem in estimating the effect of minimum wage increment. The result shows that the minimum wage increment leads to decrease of new employment and increase of the ratio of new workers who work less than 15 hours per week. Especially, women, the elderly, the youth, and under high school education level group are sensitive to the minimum wage increment.

An analysis of the correlation in port-related industries between minimum wage and employment effects, showed that it was very insignificant. However, there are some differences between commercial and temporary workers, those that are self-employed, and other workers in the private sector. Thus, while commercial workers are somewhat stable, they have a somewhat negative effect on temporary workers and self-employed people. At the Minimum Wage Council, the minimum wage hike is seen as stable because of the interaction between income and substitution effects in the labor market. According to the analysis, the port-related industries were affected more by the global economic recession and domestic economic volatility than the variables related to the minimum wage hike.

This paper explores whether or not a minimum wage increase can do much to alleviate working poor. For this purpose, I analyze transitions from working poor to working non-poor and to unemployment or non-economically active states, using KLIPS (Korea Labor and Income Panel Study). This study uses the multilevel multinomial logit model to control unobserved individual heterogenous characteristics. It finds that a minimum wage increase tends to cause a higher probability of transitions from working poor to working non-poor. It is also discovered that a minimum wage increase is not negatively related with the persistence of the working state. It is concluded that minimum wage increases are likely to be effective in improving the living standards of the 'working poor'.

Objectives: We aimed to examine the association between experience of workplace violence and musculoskeletal pain among wage workers in South Korea. Methods: We analyzed a cross-sectional survey of 29,601 wage workers from the third wave Korean Working Conditions Survey in 2011. Experience of workplace violence was assessed through three questions, "Over the past 12 months, have you ever experienced: (1) physical violence, (2) bullying, or (3) sexual harassment at workplace?" Musculoskeletal pain was measured using the three questions, "Over the past 12 months, have you ever experienced: (1) low back pain, or (2) upper limb pain(i.e. shoulder, neck, and arm), or (3) lower limb pain(i.e. hip, leg, knee, and foot)?" Wage workers could answer 'Yes' or 'No' to each of the three questions. Multivariate negative binomial regression was applied to examine the association between workplace violence and musculoskeletal pain after adjusting for confounders including self-reported physical work factors. All analyses were performed using STATA/SE version 13.0. Results: Physical violence was associated with low back pain(PR: 2.16, 95% CI: 1.77, 2.65), upper(PR: 1.65, 95% CI: 1.45, 1.88) and lower limb pain(PR: 1.81, 95% CI: 1.52, 2.15) among male wage workers whereas it was related to upper(PR: 1.86, 95% CI: 1.53, 2.26) and lower limb pain(PR: 2.95, 95% CI: 2.47, 3.53) among female wage workers. Significant association was observed between sexual harassment and upper(PR: 1.25, 95% CI: 1.01, 1.56) and lower limb pain(PR: 2.41, 95% CI: 1.97, 2.93) among female wage workers whereas the association was only significant in the analysis with lower limb pain(PR: 1.87, 95% CI: 1.17, 2.97) among male wage workers. Bullying was associated only with lower limb pains among both male(PR: 1.77, 95% CI: 1.32, 2.37) and female(PR: 2.10, 95% CI: 1.69, 2.61) wage workers. Conclusions: This study found that experience of workplace violence, particularly physical violence and sexual harassment, was associated with musculoskeletal pain among Korean wage workers.

This paper aims to analyze the Award wage system in Australia for construction workers. Considering low wages and precarious employment situation of construction workers in general, it is of advantage especially for them in Australia. Furthermore, it seems to be instructive for Korean construction workers, who stand in more precarious and unstable situation and furthermore are lack of fair wage and social safety. After strong and longstanding labour struggle in the late 19th century in Australia, it has been established a tripartite institution called as 'tribunal' between trade unions, employers, and the government. Under the highly institutionalized form of industrial relations, it functions as an arbitration and conciliation system between labour and management. The Award wage system stands in the middle point. This Award wage system including various welfare provisions is settled by the tribunal, today renamed as Fair Work Commission. In this wage system should be defined level of minimum wages according to the various skill levels, which are in turn connected with compulsory superannuation and Medicare as well as vocational education and training. Furthermore, it provides especially for the construction workers, who suffer from job instability, so-called 'portable benefits', which relate to long service leave and redundancy pay. Considering general conditions of precarious construction workers in Korea, In that respect, the Australian Award wage system would be very instructive for our social wage and safety system for construction workers.

This article tried to find out the individual wage effect of training. This Article used 1998, 1999 KLIPS(Korea Labor and Income Panel Study) panel data. The size of the individual wage effect of training was twice of tenure's, and had significance. Training had a good effect on the job satisfaction and carrier development. To overcome self selection bias, this article regressed the first difference of wage equations, but we didn't get the significant results. Dividing sample into quitters and non-quitters in order to investigate the relation between training cost and benefit, we regressed separately the each first difference of wage equation. On quitters, the individual effect of training appeared significantly, but on non-quitters, it didn't. This results mean that employer does not raise wage rate according to upgraded skill originated in incumbent's training. And the results also mean that the upgraded skill of employee who quit pre-employer is recognized by new employer, and his wage rate rises in his new job.

This paper examines the impact of internal migration on wage growth among college graduates using Propensity Score Matching methods. We define migration as moving between Seoul Metropolitan Area (SMA) and non-SMA based on the locations of graduates' first and second jobs. We also take the direction of migration into account for examining the wage premium in SMA. In order to estimate the impact of migration on wage growth, we use the Graduate Occupational Mobility Survey (2010GOMS) coupled with other supplementary data such as College Scholastic Ability Test score and local characteristic variables. The results reveals that graduates moving from SMA to non-SMA do not experience significant wage growth. However, we find that graduates moving from non-SMA to SMA experience an increase in their monthly wage about 170,000~186,000 KRW on average (9.5~10.3% of their monthly wage on the first job).

This paper, using the sample of male workers in manufacturing industry from the HCCP (Human Capital Corporate Panel) data, analyzes the effects of trade union on the level and dispersion of wages. One of the advantages of the HCCP data is that it enables a researcher to control the effect of individual firm's 'ability to pay' on wage. All relevant variables controlled, the union effect is estimated to be 5-8%. Yet this figure seriously underestimates the wage advantage enjoyed by union workers, because union sets the "price" for experience low and the price for tenure high and at the same time extends tenure of workers by adopting strong employment protection policy. The paper also analyzes the effects of union on the wage inequality. The results are mixed: overall wage inequality is smaller in union sector while standard deviation is larger when all the personal characteristics are controlled.

This study directly analyzes the wage distributions rather than indirectly looking at a few of their moments. It also investigates wage distributions using various descriptive and semi-parametric methods. The wage distributions of Korean manufacturing industries can in general be represented by three distinct forms, underdeveloped, advanced and the medium of the two. The discrepancies in these distribution forms are explained by differences in the labor-type distributions and their weights in the composition of wage distribution forms, and further clarified through various descriptive statistics based on them. However, the descriptive statistical analysis has a limit in that it shows mixed outcomes of different categoric variables. Then, this problem is resolved by applying a semi-parametric estimation of hazard function and the marginal effect evaluations of variable changes on estimated distributions not on the function. As a result of this marginal analysis, the common features and differences of categoric variables and their intensities of effects on distributions are revealed.

Nurses are medical personnel, who play a key role in supporting patient care, so it is important to supply them adequately in balance with ever increasing medical demand. But there appears severe shortage of nurses in some hospitals because of their uneven distribution, especially in small sized-hospitals and rural-hospitals. As nationwide distorted distribution of nurses in Korea is just like what monopsony model(a kind of market structure model) tells us, it is attempted to explain this situation of nurse labor market in Korea on the basis of monopsony model and presented in this paper. Specifically, determinants of nurse wage and the level of their relative employment were examined, and monopsony impact on their wage and the level of relative employment controlling those determinants were studied. Major results of this study arc as follows. The most important determinant of nurse wage level in this study was the wage level of a local community where each hospital located Hospital owner's characteristics an educational function of each hospital were also important factors. With these factor controlled, it was found that monopsony power of each hospital was negativel associated with nurse wage level as expected. 1% increase in monopsony power of hospital(measured by Herfindah-Hirschman Index) reduced nurse wage by $5,674{\sim}19,19$ won(in Korean currency). With regard to the level of relative employment, the most important determinant wa the capacity for supplying nurses of the local community. Again, hospital owner characteristics and educational function of each hospital were also important. With these factors controlled, it was found that monopsony power of each hospital was negative associated with the number of nurses per bed, as expected. 1% increase in monopsony power of each hospital(again measured by Herfindah-Hirschman Index) reduced the number of nurses per 100 bed as much as $0.46{\sim}0.67$. In conclusion. structural factors of nurse labor market influence the instability of nurse labor supply in Korea. Further consideration for these market structural characteristics needed for policy making related to nurse resource allocation.
