Understanding the mechanisms behind spatial inequality matters! For instance: what happens when job mobility slows down? Big places lose their comparative advantage... ⬇️ Productivity, wages, and the number of workers in large cities shrink ⬆️ Smaller cities expand

🎯 Key quantitative takeaways — Spatial wage disparities arise without city-level productivity gaps — Lifetime earnings are higher in bigger cities — even for workers with lower real earnings as they climb a steeper ladder

Using French matched employer-employee data, I find: 📌 High-paying jobs are concentrated in big cities  📌 Low-paying jobs are everywhere  📌 Workers access high wages in large cities as they switch from low- to high-paying jobs over time

🚨 New working paper 🚨 In large cities, wages are higher. But so are inequalities. In fact, low-wage workers earn lower real earnings there. Why? What drives spatial wage disparities? Why some workers work at lower real wages in large cities?
