Impact of pandemic-driven online education on student evaluation scores: A comparative study in natural sciences
The COVID-19 pandemic necessitated the adoption of online systems by educational institutions for infection control. The widespread implementation of online systems presented an opportunity to assess the impact of online education. However, research into the perceptions of students who directly experienced these changes remained relatively underexplored. This study conducted a comparative analysis of student evaluation of teaching scores (SET) be…
North Korea’s Covid-19 policy dilemma: Epidemic prevention conflicting with trade
BACKGROUND: Amidst the COVID-19 pandemic, striking a delicate balance between sustaining economic activity and safeguarding public health has become a crucial concern. The border closures for COVID-19 prevention have further intensified concerns for North Korea, which conducts over 90% of its trade with China and Russia, countries sharing its borders. METHODS: This study aims to scrutinize North Korea's response to these competing imperatives by …
Can Covid-19 mark a tipping point for home-based telework? Conflict between untact technology and rigid institutions in Korea
Background: Previously, Korea showed a passive attitude toward home-based telework; however, this stance rapidly changed after the COVID-19 pandemic. Sustaining home-based telework entails adjusting productivity conditions, introducing performance-based evaluations, and modifying employment rules, as required by the Korean Labor Standards Act, which demand the consent of most workers. This study aims to explore the societal and institutional shif…
How does grade inflation affect student evaluation of teaching
Student evaluation of teaching (SET) is important for assessing university instructors’ performance. However, this system seems biased as students’ grade expectations result in rewards or penalties in SET. As a fair evaluation of grades became difficult during the COVID-19 pandemic, universities implemented a relaxed grade policy that expanded the distribution of high grades. This grade inflation altered students’ expected grade. Through empirica…
Covid-19 and Age Disparity in Credit Card Expenditures in Korea: Implications on the Government Relief Fund
This study examined the difference in expenditure behavior by age group through an empirical analysis of changes in card expenditure after the COVID-19 outbreak, using card transaction data in Korea. It also investigated whether changes in card spending reflecting changes in expenditure behavior occur because of the spread of infectious diseases. A panel analysis was employed using data from 2018 to 2020. After the outbreak, total expenditure dec…
Parenthood and Life Satisfaction in Stratified Labor Market: Evidence From Korea
This study analyzes the effect of parenthood on life satisfaction with a stratified labor market using the Korean Labor and Income Study. For regular female workers at large companies, the decrease in life satisfaction due to parenthood is higher compared to that for men in a similar position due to the high opportunity cost of a career break following childbirth. For men who are non-regular employees at Small and medium-sized enterprises (SMEs),…
Uneven Use of Remote Work to Prevent the Spread of Covid-19 in South Korea's Stratified Labor Market
Background: This research analyzed whether South Korean companies adopted remote work during the COVID-19 pandemic by focusing on the dual labor market structure comprising of primary sector (large corporations) and secondary sector [small and medium enterprises (SMEs)]. Companies in the dual labor market were classified based on firm size. Methods: We used August supplementary data from the Economically Active Population Survey covering 2017–202…
Are Economic Sanctions against North Korea Effective? Assessing Nighttime Light in 25 Major Cities
This study analyzes the effects of the economic sanctions against North Korea since 2016 on the economic well-being of North Korean cities. As a proxy for economic well-being, we use nighttime light (NTL), which we estimate from 1992 to 2019 through an inter-calibration process for DMSP/OLS and SNPP/VIIRS. We found that NTL in North Korea was getting brighter up until 2009, but that the growth rate of total NTL in 25 major North Korean cities beg…
Gender inequality of job security: Veiling glass ceiling in Korea
This study analyzes the potential existence of a glass ceiling effect in Korea. Previous studies considered the wage gap between genders and could not identify a glass ceiling effect in Korea; by contrast, this study considers gaps in job security as well as wage between genders and empirically identifies the existence of a glass ceiling. Taking job security into account shows that women workers suffer from the glass ceiling effect more seriously…
Conflicting Interpretation of the Court and Government, and Uncertainty of the Wage System in Korea
Due to an abrupt change in legal adjudication, Korean companies might experience a significant rise in wage costs unless preemptive policy measures reduce the legal uncertainty in a coordinated manner. The situation in Korea is compared to that of Japan, with a similar statutory structure for employee wages and allowances
The impact of epidemics on labor market: Identifying victims of the Middle East Respiratory Syndrome in the Korean labor market
Disasters like epidemics can occur unexpectedly and affect certain groups more than other. Therefore, medical protection should be enhanced for groups vulnerable to disease and economic measures are also required for the protection of their livelihoods in the labor market to prevent unemployment stemming from inequality

Identifying the winners under the Age Discrimination Prohibition Legislation in Korea: Policy remedy for redistribution
The Korean government announced the enforcement of the Age Discrimination Prohibition Legislation (ADPL) in March of 2008. In Korea, which follows a strict seniority-based employment structure, this legislation will bring forth social benefits to those that are eligible for extended retirement by increasing their income, but it may also create a loss in social benefit by increasing the burden of employers who have to pay their salaries. This stud…
Gender difference of the informal sector wage gap: A longitudinal analysis for the Korean labor market
Unlike previous studies focusing on either market structure or gender earning gap separately, this study considers market structure as a more crucial factor in determining the gender earning gap. The estimated wage differentials between sectors from the fixed-effects (FE) model demonstrate a substantial drop in the size of wage gaps, reflecting systematic sorting between formal and informal sectors by unobserved workers’ abilities. While estimate…
How do Labor Unions Influence the Gender Earnings Gap? A Comparative Study of the US and Korea
This paper provides a comparative study of the United States and Korea regarding the effects of unions on gender earnings gaps in 2004. Using datasets representative of the population of the US and Korea, this contribution shows that gender differences in the workers' observed characteristics and the unobserved component reduce gender earnings gaps in union jobs in both the US and Korea. Fringe benefits in the union sector attract women workers w…
Affirmative Action and Corporate Compliance in South Korea
The Affirmative Action Act was introduced in South Korea in 2006 to increase female employment and correct discriminatory hiring practices. Using the combined data sets of survey and the Act's implementation plan, this paper provides logit estimation results to examine empirically how political perceptions or attitudes of firms influence corporate noncompliance with the Act. According to a corporate personnel manager survey, affirmative action wa…
Gender and Job Turnover in the Dual Labor Market: A Korean Perspective
This study analyzes gender differences in job turnover and performance in the Korean labor market by using a combined dataset consisting of the Ninth and Tenth year waves of the KLIPS (Korean Labor & Income Panel Study). The results of this empirical analysis show that the female workers in the dataset had a higher turnover rate, by a margin of 9.5 percent compared to male workers. Further, the results suggest that voluntariness and change in emp…
