Thesis Title - Cross-border Labor Mobility, Attitudes and Political Preferences

I work on migration economics from a contemporaneous as well as a historical point of view. I enjoy exploring original data sources that can allow us to better understand our past. I also give a lot of importance to scientific integrity and therefore promote open-source and reproducible research.”

Thesis Title: Cross-border labor mobility, attitudes and
political preferences

Supervisor: Michel Tenikue

Thesis Start Date: 01-10-2020

Thesis Defense: 26-11-2024

Research AreaMy research focuses on the social and political aspects of international migration. I explore whether migrants are affected by the political landscape in potential destinations. Most papers I read in my undergraduate studies were about the effect of immigration on voting behavior. It seemed natural to me to explore the effect of those attitudes on future migration flows.

Post-PHD Aspirations: I am looking for a postdoctoral position in the fields of economic history and migration economics. I have a project that combines those two areas by taking advantage of novel historical sources, and I would like to explore it further. Apart from a position in economics, I am also interested in Research Software Engineer (RSE) positions that would allow me to build and teach software in an academic setting.

Unequal exposure to migration across space and regional development inequality: Evidence from Senegal

This paper examines how heterogeneous exposure to internal and international migration across space affects economic activity, regional development, and welfare inequality in Senegal. First, it documents how heterogeneous migration is across Senegalese departments, considering both size and destination choice (internal capital regions, internal other regions, international OECD, international neighbors, rest of the world). 

Second, it shows that the spatial allocation of labor across space in Senegal is jointly determined by internal and international migration and argues that the failure to account for the two dimensions is likely misleading. 

Third, it develops a quantitative spatial development model that features a small open developing economy with multiple regions, a dual labor market (formal and informal sectors), a rural-urban divide, and an education premium. 

The model jointly endogenizes migration decisions, education decisions, sectoral location choices, and employment density across regions. Applying the model to a rich and spatially detailed Senegalese data, its shows that regions with negative net out-migration tend to experience per capita income gains, in contrast to regions with positive net out-migration. Moreover, higher exposure to OECD destinations correlates with increased positive externalities through endogenous human capital formation and higher remittances. This suggests that unequal exposure to migration increases inequality at the local level, depending on which destination group the region is most exposed to. At the country level, however, migration reduces income and welfare inequality by 11.6 and 7.3 percent, respectively. These effects stem from reduced spatial misallocation of labor, agglomeration forces, endogenous human capital formation, and remittance flows.

Thesis Title: Essays in the Economics of Human Mobility and Labor Markets 

Supervisor: Bertrand Verheyden

Thesis Start Date: 01-11-2020

Thesis Defense: 31-05-2025

Research Area:

The majority of my thesis deals with the labor market effects of immigration, where I focus on heterogeneity and explore new mechanisms of adjustment. One project assess labor market effects in the context of efficiency wage theories, the other zoom in on effects on the unemployed.

What fascinates me about this topic is how fundamental it is to understand the functioning of labor markets, yet how many adjustment mechanisms exist, which make for nuanced and ultimately unclear answers.

Adrij Chakraborty

Thesis Title - Immigration policy and migrant assimilation

I’m pursuing a PhD essentially because I love asking ‘Why?’ more than a three-year-old. In this sense, I am curious to explore the specifics of the broader areas that I work on – labor economics and causal inference. While I enjoy academic research, my interests also lie in evidence-based reportage and data science. On earning my Ph.D. degree, therefore, I am open to considering my career both in academia and outside of it.”

Thesis Start Date: 15-11-2022

Thesis Defense: 2026-2027

Research AreaConsidering that trust is an important determinant of life satisfaction, economic growth and firm performance, I profit from the specific context provided by Luxembourg to investigate the transmission of social norms from the high-trust Germans to the low-trust French. My contribution is tackling social norms transmission in a controlled experimental setting and using a third country as the “mixing bowl”, as opposed to studies on assimilation into the predominant culture. Through his five-treatment experiment, I expect to identify a convergence in trust between the French and the Germans, with the final equilibrium being slightly higher than Luxembourg’s trust levels. Cultural diversity and internationality conditional on non-segregation are advanced as the main mechanism behind this expected convergence. Rather than being a geolocated research question, I argue that this study has applications and policy implications for most countries in all continents.
