“Parent-child interaction and Child Outcome: Evidence from a Randomized Intervention” Labour Economics (Oct. 2018) with Wolfgang Schulz, Tanja Zimmermann and Kurt Hahlweg. https://doi.org/10.1016/j.labeco.2018.08.003

Highlight: Randomized parenting intervention that improves parents' discipline strategies (parenting style) for their children in early childhood improves the children's behavioral outcomes in early adolescence. Parenting styles (harsh discipline, positive discipline) have causal effects on child outcomes.

"Early childhood parenting and adolescent bullying behavior: Evidence from a randomized intervention at ten-year follow-up" Social Science & Medicine (Aug. 2021) with Kurt Hahlweg and Wolfgang Schulz. https://doi.org/10.1016/j.socscimed.2021.114114

Highlight: Randomized parenting intervention that improves parents' discipline strategies (parenting style) for their children in early childhood makes the children less likely to bully their peers in early adolescence. Bullying seems distinct from other problematic behaviors.

"Home-Tutoring Services Assisted with Technology: Investigating the Role of Artificial Intelligence Using a Randomized Field Experiment" Journal of Marketing Research (Feb 2022) with Minki Kim, Do Won Kwak and Sol Lee. https://doi.org/10.1177%2F00222437211050351

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.

Other Publications

"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.

Working Papers

"Effects of Childhood Peers on Personality Skills" with Shuaizhang Feng and Zhe Yang. RnR at Journal of Labor Economics. Download.

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.

"Prosocial Vaccination" with Bakhtawar Ali, Syngjoo Choi, and Avner Seror. Submitted. https://doi.org/10.1257/rct.8035-1.0. Download.

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.

"Medical Marijuana Legalization and Parenting Behaviors: An Analysis of the Time Use of Parents" with Cynthia Bansak. Submitted. Download.

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.

"Mental Health Consequences of Working from Home during the Pandemic" with Yu Kyung Koh and Jinseong Park. Submitted. Download.

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.

"The Economics of Parenting Skill and Child Development" (undergoing revision) with Jong Jae Lee and Ji-Liang Shiu. Download.

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.

"Parental Migration, Parenting, and Children’s Skill Development", with Shuaizhang Feng, James Heckman, and Yujie Han.
