Tsai and Trinidad (2025) investigate how intercultural roommate pairings affect college outcomes among low-income U.S. students. The study centers on Berea College, a tuition-free liberal arts institution in Kentucky that primarily serves economically disadvantaged populations. Leveraging institutional data from over 6,600 domestic students between 2000 and 2015, the authors evaluate whether being paired with an international roommate in the first year influences academic performance and persistence throughout college.
Using quasi-experimental methods, including inverse probability weighting (IPW) and robustness checks through augmented and matching estimators, the researchers compare students with and without international roommates while accounting for demographic factors such as race, gender, and transfer student status. The findings reveal that domestic students paired with international roommates achieved significantly higher first- and second-year GPAs (approximately 0.14 and 0.10 points higher, respectively) and showed a modest improvement in second-year retention (about four percentage points). However, the benefits gradually diminished over later years, and no significant effects were found for long-term persistence or six-year graduation rates.
The authors interpret these results through the lens of peer effects and diversity in higher education. They suggest that intentional intercultural roommate pairings create structured opportunities for cross-cultural engagement that may counteract homophily in predominantly white, low-income settings. This exposure not only enhances academic habits and motivation but also fosters inclusivity and openness among domestic students.
Overall, the study provides empirical evidence that low-cost, policy-driven diversity interventions, such as pairing domestic and international students, can meaningfully improve early academic outcomes for disadvantaged students. While the effects do not extend to graduation, the research highlights the importance of designing inclusive residential environments that promote sustained intercultural interaction as a pathway toward educational equity.
