Nicolas Longuet-Marx

Nicolas Longuet-Marx is a Ph.D. student in Sustainable Development at the School of International and Public Affairs at Columbia University.

Before joining Columbia, he earned a Master's degree in Economics from the Paris School of Economics and a Bachelor’s degree in Economics from Paris Sciences et Lettres. He also worked for the French Development Agency (AFD) at their Central Asia regional office in Tashkent, Uzbekistan where he was working on energy and water projects. Longuet-Marx was also a visiting fellow at UC Berkeley in the Spring of 2023.

His research interests are centered around Political Economy questions and their intersection with topics in Environmental Economics and Empirical Industrial Organization. 

Longuet-Marx's main research project, supported by the Center for Political Economy, studies the reasons for the increasing educational level of Democratic voters in the US over the recent period. He develops a unified framework for analyzing the interaction of political demand and supply resulting in political outcomes combining fine-grained electoral results with detailed candidate positions. He wrote a research paper studying this question of political realignment in the US from a historical perspective, together with Ilyana Kuziemko and Suresh Naidu entitled: "Compensate the Losers?” Economic Policy and Partisan Realignment in the U.S." 

Longuet-Marx has been working on other topics in Political Economy and, in particular, published a study of how government performance affects citizens' beliefs about democracy in the Journal of Politics, with Michael Becher and Vincent Pons.

Longuet-Marx is also working on projects studying the impact of labor market outcomes on political behavior, using the dataset built for the project supported by the CPE. Longuet-Marx works, together with Matilde Bombardini, Frederico Finan, Suresh Naidu, and Francesco Trebbi, on voters’ environmental preferences and specifically the role played by green and “dirty” job creation and job destruction to forge ideological stances and voting behavior.

Longuet-Marx also studies, together with Ethan Kaplan, Suresh Naidu, and Aaron Schein, to what extent labor market policies influence agents’ political behavior. Specifically, it examines variations in city-level and county-level minimum wages to determine their influence on voter behavior in terms of registration, turnout, election outcomes, and campaign contributions.
