Highlight: AI-based assistance to tutors (service providers), providing them with analyses and guidance on tutoring their students, improves students' outcomes (service outcomes). Not all tutor adopt the assistance technology, and those who eagerly adopt do not always benefit more.
"Parental factors and children’s screen time during the COVID-19 pandemic in South Korea" Child Psychiatry & Human Development (May 2022) with Won Kay Kim and Yu Kyung Koh. https://doi.org/10.1007/s10578-022-01366-z
Highlight: Children's screen time during the COVID-19 pandemic is positively associated with parents' depression, parents' lack of self-care, family conflict, and parents' fear of the pandemic. Whereas previous literature primarily focused on the effects of parenting behavior, we find important roles played by complex family factors in determining children's screen time.
Publications in Korean
가정환경, 학교환경, 학생행동요소가 학업 성취에 미치는 영향: 요소간 보완성과 대체성을 중심으로. 노동경제논집 (Sep. 2021) Effect of Home Environment, School Environment, and Student Behavior on Academic Achievement. Korean Journal of Labor Economics (Sep. 2021) KCI link. Online Appendix. Download.
Highlight: CES skill production function is estimated using panel data following students through middle and high school, finding greater elasticity of substitution for the earlier period. For under-achieving students, own effort dominates household income and school quality as the key input.
"Case Study: Improving early childhood parenting as a strategy to reduce adolescent bullying." Book chapter for The Handbook of Anger, Aggression, and Violence: Causes, Pathology and Treatments (Springer Nature). Accepted.
Highlight: We find peer effects on personality skills of primary school children, showing that peers are inputs in childhood noncognitive skill development. Children's characteristics that determine their own personality skill development determine their peers' personality skills but not their academic achievement, suggesting that peer effects may be skill-specific.
"Impacts of the COVID-19 Crisis on Single-Person Households in South Korea" with Haeil Jung and Gihyeon Hong. RnR at Journal of Asian Economics.
Highlight: Consumption of single-person households, especially in 50--65 age group and in spending related to formal and informal insurance mechanisms, was negatively affected by the COVID-19 pandemic. Single-person household is highlighted as a growing demographic group that is particularly vulnerable to economic shocks because of their limited access to informal insurance.
Birth Order Effects, Parenting Behaviors, and Son Preference, with Shaoda Wang. RnR at China Economic Review. Download.
Highlight: We find negative birth order effects among adolescents in contemporary China in academic achievement (outcome) and parenting style (channel; harsh punishment). Son preference (mechanism) plays limited role in explaining the results, unlike studies from earlier generations of Chinese.
Highlight: We show that people are motivated by prosocial motives in decisions to vaccinate, using an experimental data in a large developing country. We explain our findings using a model of reference-dependent preference with respect to prosocial behavior and calibrate prosocial loss aversion parameter to be around 2.
Highlight: We show that parents in the US spend more time taking care of their children when they have legal access to medical marijuana. We provide suggestive evidence that the parents used marijuana for medical purposes as intended rather than engaging in marijuana abuse.
"Effects of Ambient Temperature Exposure on Cognitive Development in the First 1,000 Days", with Wenjie Wu, Zhe Yang, and Ai Yue. Submitted.
Highlight: Workers working from home during the COVID-19 pandemic were more likely to experience loneliness, lethargy, and sadness, especially if they were also responsible for housework, but not if they lived with children. We suggest work-family facilitation as a potential explanation.
Highlight: Parents' choice of discipline (parenting style; positive vs. harsh discipline) is driven by their ability to communicate their message to their children through discipline (parenting skill). Positive discipline is more consistent, easier for children to understand, but more difficult for parents to implement. Parenting skill is found to be an important determinant of achievement gap of children across household SES.
