Does talent migration increase inequality? A quantitative assessment in football labour market

I analyze the links between talent migration and cross-country inequality by exploiting the 1995 elimination of mobility restrictions on the European football labor market. I develop a simple model and employ an empirical dataset to estimate its parameters. Through simulation analysis, I compare actual data with a counterfactual no-mobility restriction trajectory, and conclude that the elimination of mobility barriers increases not only cross-country inequality by 25%, but also global output in the football economy by stimulating the production of new talent in Africa, Latin and Central America.
