Abstract: A large body of research has highlighted the substantial and persistent earnings losses suffered by displaced workers, referred to as the “scarring effect.” However, policy interventions aimed at alleviating these losses remain largely unexplored. This paper bridges this gap by evaluating the long-term effects of unemployment insurance (UI) on post-displacement outcomes. Leveraging cross-state variations in UI policy over time, I find that a 13-week extension in maximum UI duration reduces long-term earnings losses by 10-15% over a 10-year period. This reduction is primarily driven by an increase in hours worked, with minimal impact on wage rates. Conversely, UI replacement rates have a small and largely insignificant effect on earnings, wage rates, and labor supply. These patterns are consistent across different educational levels, racial backgrounds, and economic conditions at the time of displacement. To explore the mechanisms, I show that the non-pecuniary aspects of a job improve with longer maximum duration, and explain a substantial portion of the effect of maximum duration on labor supply. A search model incorporating the intensive margin of labor supply and non-pecuniary benefits suggests these patterns are driven by shifts in reservation utility. The model indicates that either there is a low correlation between non-pecuniary benefits and wage rate offers along with a small variance in wage rate offers in the market, or that workers prefer non-pecuniary benefits over wage rates, or a combination of these two factors.
Abstract: This study investigates the impact of maternal job displacement on children's educational attainment in single-mother households. The previous literature, which often relies on propensity score matching to construct a control group for households experiencing displacement, consistently reports negative effects of maternal displacement on children's outcomes. However, this study finds that, after accounting for pre-displacement partnership dynamics, partner income, and the duration of single motherhood, the effects of displacement on children's educational attainment are generally small, and in some cases, even positive. These positive effects are primarily driven by children whose mothers were displaced during middle childhood, while those experiencing displacement in adolescence exhibit negative impacts. To explore these patterns, I examine changes in household resources following displacement. The findings show that initial earnings losses are largely mitigated by safety net programs, particularly unemployment insurance benefits. Additionally, displaced single mothers are more likely to find a partner with higher incomes in the years following displacement. As a result, although the household incomes of displaced mothers are initially lower than those of mothers who were not displaced, they eventually surpass them in the long-term. However, this trend is less pronounced for mothers displaced during their children's adolescence. This income trajectory helps explain the positive effects of displacement during middle childhood and the negative effects observed during adolescence. Further investigations into other potential channels, such as early academic performance, mental health, and self-reported health, do not provide additional explanations for the patterns of educational attainment.

Abstract: This paper examines the impact of shotgun marriages on birth outcomes, with a focus on the mediating role of Confucianism in South Korea using administrative birth records. Although previous studies have investigated the effects of marital status on birth outcomes, the cultural mechanisms underlying these effects remain largely unexplored. Confucianism, which has shaped South Korean society for over a thousand years, stigmatizes sexuality and places a strong emphasis on chastity. This cultural influence helps explain why out-of-wedlock births and births from shotgun marriages have historically been rare, as they defy societal norms. South Korea's recent generational shift away from Confucian values, along with substantial regional variation, provides a unique setting to investigate how culture moderates the effects of shotgun marriages on birth outcomes. We find that shotgun marriages are associated with a 9-gram decrease in birth weight and a 0.09 percentage point increase in the probability of low birth weight. Using the third-child sex ratio (TSR) as a proxy for Confucian cultural strength, we find that in regions and years with stronger Confucian influence, the negative impact of shotgun marriages is more pronounced. A one standard deviation increase in TSR further reduces birth weight by 6 grams and raises the probability of low birth weight by 0.14 percentage points. Alternative explanations, such as differences in prenatal care, selective abortion, and selection into shotgun marriages do not fully account for these findings.
“When Genetic Propensity and Family Environment Collide: Religiosity and Same-sex Sexual Behavior,” (with Pietro Biroli, Nicholas Papageorge, Kevin Thom, Robbee Wedow).
Abstract: This paper examines how a polygenic index for same-sex sexual behavior interacts with adolescence environments, particularly parental religiosity. Our preliminary findings show that male adolescents with the same polygenic index raised in religious households experience worse mental health, higher suicidality, lower educational attainment, and are more likely to engage in risky behaviors compared to those from less religious households. However, this pattern does not appear for female adolescents. This study highlights the importance of understanding how family environment heterogeneity influences socioeconomic outcomes for sexual minorities. We plan to expand our analysis by including more individuals with available genetic data.
