The objective of this study is to verify the moderated mediating effects according to the severity level of a disability as well as the mediating effects of job security in the relationship between difficulties in the workplace of the disabled wage workers caused by the COVID-19 pandemic and their life satisfaction. As a result of analysis using SPSS ver. 25 and PROCESS macro, the difficulties within the workplace caused by the COVID-19 pandemic had a negative influence on life satisfaction through the job security of the disabled wage worker. In other words, it was revealed that the level of difficulties being faced by the disabled wage workers, which were caused by the COVID-19 pandemic, hinders their life satisfaction through job security. In addition, no moderating effect according to the severity level of disability was identified in the relationship between these variables. This is translated that difficulties in the workplace caused by the COVID-19 pandemic reduce job security and life satisfaction of the disabled wage workers regardless of the severity level of the disability. Based on the results thus far, this study further discussed the institutional implications for promoting the job security and life satisfaction of the disabled wage workers under the COVID-19 pandemic situation.

This study aims to investigate the changes in the employment structure of occupational groups by job characteristics and analyze the factors influencing wage premiums in local labor markets from 2010 to 2020. This study's analysis involves three primary steps. First, the occupational characteristics data from the Korea Network for Occupations and Workers are subjected to an exploratory factor analysis, and then a non-routine task intensity index is calculated by each occupations. Then, we conduct an exploratory analysis of changes in the distribution of employment by occupation from 2010 to 2020 by combining data from the Population Census with data from the Korean Labor and Income Panel Study to construct individual-level and regional-level data. Thirdly, we employ a hierarchical linear model to examine the individual-level and regional-level factors influencing wage premiums. Since 2010, the proportion of employment in occupations requiring non-routine task has continued to rise and now dominates the metropolitan labor market. Moreover, agglomeration effects resulting from urbanization produce a substantial wage premium for wage workers in occupations requiring non-routine tasks. This study seeks to provide policy implications to mitigate inequality and polarization in local labor markets by empirically analyzing the transition of occupational structure and wage inequality in relation to the local labor market context.

This paper examines why older wage workers leave their jobs and what determine the hazard of retirement. Major results are as follows. First, aged workers leaving their jobs because of formal mandatory retirement are relatively few in number and largely males employed in large establishments. Second, a higher hourly wage is associated with a greater retirement hazard, especially among male employees of large firms. Third, informal mandatory retirement puts a strong pressure towards retirement among older female workers. Fourth, poor health is the primary reason for retirement among older workers, especially for females and small-firm employees. Finally, reasonable hours and greater flexibility of work tend to lower retirement hazard. We discuss some implications of the results for old-age labor market policies.

This study analyzes the difference of search efforts and labor market performance between employed searchers and unemployed searchers, using GOMS(Graduates Occupational Mobility Survey) data collected by Korea Employment Information Service. The results show that unemployed searchers concentrated on the job search more actively, and their reservation wage decreased more rapidly than that of employed searchers. Therefore, considering only new jobs, the probability of employment was lower and the wage was higher for employed searchers than for unemployed searchers. However, both the employment probability and the wage were higher for the employed searchers, if analyzing all jobs including existing jobs of employed searchers. The results of this study imply that the employed search may be more effective strategy than the unemployed search.

This paper presents a simple two-sector general equilibrium model of noncomparative advantage trade between structurally identical advanced economies. Attention has focused on the effects of trade in information technology (IT) goods and services on the wage inequality in the digital economy. The model confirms and illustrates that wage inequality in the digital economy reflect trade in IT goods and services between advanced economies. In particular, this paper shows that even though the relative price of skilled labor-intensive technology good is declined with trade in IT goods and services, the wage of skilled labor increases. The reason is that as Jorgenson (2001) has empirically found, the price elasticity of demand for the technology goods is elastic.

Purpose - This study empirically analyses the changes in unemployment rates to understand push factors of generating wage pressure and how it affects the aggregate demand in Korea and the United States. We use a structural macroeconomic model which is centered on the labor market and simultaneously explains the natural rate of unemployment and deviations. Research design, data and methodology - We attempt to empirically analyse the unemployment rates through two countries to analyse the economic effects of real wages and aggregate demand between 2000 and 2016. We introduce having estimated the whole model that the growth of unemployment into the part caused by each of these factors. Results - The results of this study show that in the long run, there is not only a natural level of employment but also a natural level of real demand are positively related. in the short run, demand can vary from bring about changes in employment by means of price or wage surprises. Conclusions - The pressure of demand in the labor market shows up strongly in both countries. The estimated labor-demand equation are consistent with this framework and generally have well defined real wage and demand effects.

Using the data from 1980 to 2017, I show the long-term trends in the gender wage gap in Korea and analyze factors using decomposition method. It tended to decline until the 1990s, but gradually slowed after the 2000s. Gelbach(2016)'s decomposition method is used as an alternative rather than Blinder-Oaxaca decomposition. The results show that the proportion of explanation of traditional factors, such as age, education, firm size, industry and occupation, are continuously decreasing in explaining the gender wage gap. Expecially, the proportion of explanation of age and that of education have decreased, and that of industry tended to decrease in the 1990s but to increase after the 2000s.

Some fact-findings which were gained as results of regression analysis with Workplace Panel Survey data about whether Employee Participatory High Performance Work Practices could help to increase the compensation of workers are as followings. Firstly. though High Performance Work Practices wert generally estimated to have positive effects on management performance of establishments, their positive effects were not so significant except in cases of some practices. Secondly, the wage increase effects of the main High Performance Work Practices were much stronger with statistical significance. Thirdly. in case of unionized establishments. the wage increase effects of the main High Performance Work Practices were estimated to be much stronger than in the Don-unionized.

This paper compares the earnings effect of inter-industry technology differences between the self-employed and wage earners. It is assumed that primary skills utilized by the self-employed and paid workers differ in nature, and thus the earnings effect of technology differences and its skill-biasness also differ for each type of workers. For the empirical analysis. Heckman's two-stage method and quantile regressions are fitted to Korean panel data. The earnings effect of technology differences turns skill- biased for wage earners (job-specific skills), but prevails for all self-employed workers (entrepreneurial skills) regardless of their schooling level. This sectoral difference holds for each different quantile of earnings distribution.

We find that there is the height premium in the Korean labor market. The wage increases by 1.5% with a centimeter increase of height among male workers of ages 30-49. This estimate is barely affected by family backgrounds such as a worker's father's education or occupation. It is rejected that a worker's height is a proxy variable for his health, which increases his wage. The height premium is unrelated with obesity. It is not also supported that a worker's height affects his wage through his occupational choice. We partly confirm that a worker's height affects his wage through his educational choice. The estimated height premium of 30's in Korea is comparable to that of age 33 in Great Britain.
