The Effects of Universal Free Lunch Provision on Student Achievement: Evidence from South Korea
(Will be updated soon)
Abstract This paper examines the impact of the Universal Free Lunch Program (UFLP) on student achievement in South Korea. I leverage the staggered rollout of the UFLP across South Korean provinces and employ difference-in-differences strategies to estimate the causal effects of the program. Taking advantage of rich school-level data, I find that providing free lunch to all students leads to improvements in academic achievement on average. I also test for heterogeneous effects and find that the benefits of the UFLP exhibit universally across different baseline participation in the means-tested lunch subsidy. After exploring numerous potential mechanisms including changes in school lunch participation, I find suggestive evidence of the increased participation in and expenditures on the after-school programs that are not free. These results suggest that parents used the saved lunch fees for educational investment and highlight the importance of mental accounting.

Policing and Prosecuting Drug Offenses in Nashville: Drug Free School Zones (joint with Aria Golestani and Jaclyn Rosenquist)
Abstract Drug free school zones (DFSZs) increase penalties for drug crimes committed near schools or places where children gather. In this study, we utilize a unique data set to estimate the causal effect of DFSZ enhancements on court sentencing outcomes in Nashville, TN. We exploit the variation of arrestees’ location and use the instrumental variable two-stage least squares estimator to study the causal effect of being charged with the DFSZ enhancement. Our estimates suggest that being charged with the DFSZ enhancement increases the likelihood of an individual being found guilty by 11 percentage points and increases the sentence length by roughly 1 year. Notably, we find that enhancement charges against eligible offenders are more likely to be applied to Black arrestees than White arrestees, leading to lasting impacts across races in sentencing outcomes.

The Effects of Old-Age Pension Receipt on Elderly Employment and Health: Evidence from South Korea
Abstract Public old-age pensions are an important component of the social safety net in many countries. The objective of this paper is to estimate the causal effect of pension receipt on employment and health by exploiting exogenous changes in the full retirement age under South Korea’s public pension system. South Korea is experiencing one of the most rapid and severe aging society problems, which makes it a good example for studying this issue. When I account for the endogeneity of employment and health with respect to pension receipt, I find that receiving a pension decreases employment and improves self-reported health.
