I am an applied microeconomist with research interests in labor economics, international trade, and migration. My work combines quasi-experimental methods with large-scale administrative and survey data to study how policy interventions and economic shocks affect individual outcomes and market dynamics.
In my job market paper, The Effect of Refugees on Bilateral Trade between Host Countries, I provide the first causal evidence that refugees affect bilateral trade between the countries that host them. Using the Syrian displacement after 2011 and a structural gravity model, I find that a 10% increase in the joint stock of Syrian refugees in a host-country pair raises bilateral trade by about 0.3%. The effect comes from the post-2015 wave and is concentrated in food, textiles and chemicals.

The Effect of Refugees on Bilateral Trade between Host Countries
Draft upon request
Abstract
This paper provides the first evidence of the causal effect of refugees on bilateral trade between host countries. Using the post-2011 Syrian displacement as an empirical case study, I estimate a structural gravity model on a balanced panel of 41 countries in the Middle East and North Africa (MENA) and Europe over 2000–2020 covering nine manufacturing sectors. On average, a 10% increase in the joint stock of Syrian refugees within a host-country pair increases bilateral trade by approximately 0.3%. This effect is primarily driven by the post-2015 displacement wave, is concentrated in the food, textile, and chemical manufacturing sectors, and operates along the intensive rather than the extensive margin of trade. A general-equilibrium counterfactual delivers on average 0.05% welfare gains across the studied host countries. The empirical result is robust across alternative functional forms of the treatment, alternative estimators, sample variants, and further sensitivity diagnostics.

The Effect of Mobility Restrictions on Refugees
Draft upon request
Abstract
We study a 2016 policy that prohibited refugees in Germany from moving across federal states for three years after receiving asylum. The restriction sharply reduced refugees' cross-state mobility rates from 25% to 3%. We estimate the causal effects of the restriction using a difference-in-differences design comparing refugees who received asylum before and after the policy across states with high and low pre-policy outmobility rates. Labor market outcomes are largely unaffected, with positive earnings and employment effects among refugees assigned to the southern states of Bavaria and Baden-Württemberg. The mobility restriction reduced the share of refugees living in dense urban areas with high foreigner shares. However, restricted refugees substituted toward the largest, densest, and most diverse cities within their initially assigned states.
No Ripple in the Pond: Exposure to Refugees and Native Well-Being
R&R at Journal of Population Economics
Abstract
This paper examines the impact of forced immigrants on the subjective well-being of the natural-born population in Germany. The empirical analysis covers a period from 2014 to 2019 and integrates various sources of administrative data on asylum seekers at the district level with individual-level survey data from the German Socio-Economic Panel (SOEP). The empirical strategy follows an instrumental variable (IV) approach using two different instruments.
The Downfall of Assad: Syrian Refugees' Settlement Intentions after the Unexpected Regime Change
IAB Discussion Paper 09/2025 · R&R at PLOS ONE
Abstract
On December 8, 2024, the sudden collapse of Bashar al-Assad's regime abruptly changed Syria's political landscape and reshaped the return prospects for millions of Syrians living abroad. We exploit this unanticipated regime change as a natural experiment to estimate the causal impact of homeland developments on refugees' settlement and return intentions. Drawing on novel survey data from Germany, launched just days before Assad's fall, we find that the regime collapse significantly affected the expressed settlement intentions of Syrians in Germany. However, we find no effect on concrete short-term emigration plans, suggesting that increased return aspirations reflect forward-looking intentions rather than immediate behavioral change.
