IFDP Paper: Economic Diversity and the Resilience of Cities

François de Soyres, Simon Fuchs, Illenin O. Kondo, and Helene MaghinWe develop a framework to assess how economic shocks affect local labor markets and worker welfare, with a focus on city-level economic diversity. Using detailed worker flow data across cities, sectors, and occupations, we construct theory-consistent welfare measures. Our approach combines a dynamic discrete choice model with a dual representation that captures both direct effects and the insurance value of local economic diversity.
