Existing studies show the underground economy negatively affects socioeconomic development, focusing on economic and institutional aspects as underlying factors driving its existence. This study examines the relationship between tax reform and the underground economy in 23 developed and emerging countries from 1990 to 2015. Our empirical analysis indicates that tax reforms increasing the societal tax burden expand the underground economy. Notably, expanding the tax base, rather than increasing t

This study examines the effect of employment on crime in South Korea. The sharp 16 percent increase in the minimum wage in 2018 significantly affected low-income workers, particularly the young and elderly. Using the interaction between annual minimum wage changes and age groups vulnerable to such changes within local districts as an instrumental variable for employment, the analysis identifies the impact of employment on crime rates. The results show that improved employment conditions lead to

This study investigates the impact of smoking on the labor market performance of college graduates, utilizing representative data from South Korea. To mitigate endogeneity concerns, we employ the average cigarette price during participants’ college years as an instrumental variable for smoking behaviors. The findings reveal a detrimental effect of smoking on the labor market outcomes of college students. Smokers are significantly less likely to secure employment, and if employed, they tend to ea

This study examines the impact of a consecutive double-digit hike in Korea's minimum wage from 2018 to 2019 after the impeachment of President Park Geun-hye as an exogenous shock on the employment of multinational enterprises (MNEs). Notably, this topic has received limited attention in extant literature. Using a firm-level dataset covering the period 2006-2020, we find that MNEs respond to increases in the minimum wage by reducing their total employment size, including both regular and temporar

본 연구는 선거관리위원회 평가에 영향을 미치는 요인으로 민주주의 제도 신뢰, 선거관리 참여 경험, 정치 이해도에 주목하고, 이들 간의 상호작용을 설문조사 자료를 통해 실증적으로 분석했다. 첫째, 시민의 민주주의 제도에 대한 신뢰 수준이 높을수록 선거관리위원회를 긍정적으로 평가하는 경향이 나타났다. 둘째, 투·개표 등 선거관리 업무 참여 경험은 선거관리위원회 평가에 조절 효과를 보였으며, 그 효과의 방향은 투·개표 사무원과 참관인 간에 상이하게 나타났다. 셋째, 정치 이해도는 선거관리 업무에 참여한 시민의 선거관리위원회 평가에 부분적인 조절 역할을 수행하는 것으로 분석되었다. 이러한 결과는 선거관리위원회 평가에 관한 학문적 논의를 확장하는한편, 선거관리 참여 경험 증진과 정치 이해도 제고를 위한 정책적 시사점을 제공한다.
