SITE Seminar | Transnational trauma: Mental health effects of war on expatriates

Join us for the next SITE Seminar! On November 4, 2025, Mounir Karadja (Uppsala University) will present the study “Transnational Trauma: Mental Health Effects of War on Expatriates,” co-authored with Akib Khan, Linna Martén, and Jimena Romero Pinto. Using Swedish administrative data, the research reveals how the 2022 Russian invasion of Ukraine triggered a sharp increase in anxiety, insomnia, and later depression among Ukrainian migrants—highlighting the profound mental health toll of conflict even at a distance.

Working paper title: Transnational Trauma: Mental Health Effects of War on Expatriates

Abstract

We investigate the impact of the 2022 Russian invasion of Ukraine on the mental health of Ukrainian migrants living abroad, leveraging comprehensive administrative data on medical prescriptions in Sweden. Despite the physical distance from danger, expatriates may still be affected by home-country conflict through the social, economic, or national ties they have to their homeland. To isolate the causal effect of indirect war exposure, we use the synthetic control method, comparing the outcomes of Ukrainians to a weighted average of other migrant groups in Sweden. Our results indicate an immediate deterioration in the mental health of Ukrainian expatriates following the invasion, with a marked increase in the take-up of anti-anxiety and insomnia medications. Furthermore, the uptake of anti-depressants rises significantly in the third quarter, indicating a potential shift towards medications for more long-term conditions. These effects are driven by women, although it is possible that men face mental health challenges without seeking medical care. We find little evidence that family situation, legal status, or economic conditions are important mediators of the effect.
