研究室紹介
Professor Youjin Hahn's research lab specializes in development economics and education economics, with a strong focus on the long-term impacts of social policies on women's empowerment, particularly in low- and middle-income countries. The lab investigates how education interventions—such as school stipends, single-sex schooling, and peer grouping—shape educational outcomes, labor market participation, fertility, and gender equality. It also explores the effects of early-life environmental shocks, such as cold weather, on child health and development. The research combines rigorous empirical methods, including randomized experiments and event study designs, to inform evidence-based policy.

Selected Papers
15In 1994, Bangladesh introduced the Female Secondary School Stipend Program that made secondary education free for rural girls. This paper examines the long-term effects of the stipend program on education, marriage, fertility, and labor market outcomes of women. We find that the stipend increased years of education for eligible girls by 14%–25%. These girls were more likely to get married later and have fewer children. They also had more autonomy in making decisions about household purchases, he
We examine mothers' relative labour market outcomes around the first childbirth in South Korea, a country with the highest gender pay gaps and the lowest fertility rate among the OECD countries. Using an event study approach, we find that while fathers remain unaffected, mothers' earnings drop sharply by 66.2 per cent over the long run, mostly driven by a reduction in labour force participation. For women who continue to work, motherhood lowers the probability of entering male‐dominated occupati
Abstract Students’ out‐of‐school activities and time use can play a crucial role in facilitating the effect of schools on students’ achievement. Using data from Seoul, South Korea, where students are randomly assigned into schools, we show that when single‐sex schools improve students’ test performance, their effect is positive on students’ time spent on study‐related out‐of‐school activities. Our results indicate that out‐of‐school activities explain roughly 21%–30% of the effect of single‐sex
Abstract We randomly assigned 115 primary schools in Bangladesh to one of two settings: children studying in groups with friends and children studying in groups with peers. The groups consisted of four people with similar average cognitive abilities and household characteristics. While the achievement of male students was not affected by the group assignment, low-ability females with friends outperformed low-ability females working with peers by roughly 0.4 standard deviations of the test score
This study examines the effects of early life and in utero exposure to cold weather shocks on the incidence of growth stunting for children under age five in Tanzania. We find that an increase of 10 percentage points in the proportion of days with temperatures below 15 degrees Celsius (one standard deviation below the long-term average) is associated with an increase in the probability of stunting and severe stunting by 2.0 and 1.4 percentage points (equivalent to 5.5 and 9.7 percent of the mean

In an era of uncertainty in the tourism and hospitality industry, hotels should inevitably provide their unique value attached to their space. In this circumstance, global hospitality groups have been creating lifestyle brands in line with the latest trend. Even with the rapid growth of lifestyle brands, the concept of lifestyle hotels is still vague. Besides, lifestyle hotels, especially in South Korea, tend to be developed as multi-purpose complexes combined with retail. Therefore, lifestyle h
