Resumen: Using a rich database on Italian manufacturing firms, we test the hypothesis that self-selection mechanisms differ from market to market. We observe significant ex ante productivity differences between firms starting to export to distinct geographical areas. Country characteristics such as size, distances, and productivity are some of the sources that make the entry costs market specific.
