Recent studies documenting the increase of industrial concentration have raised concerns about an era of monopolies, growing profit shares, and low economic dynamism. Using US data, this column investigates the concentration of import sales by country of origin. The results show that among foreign firms selling to the US, the concentration of sales has remained stable by origin country, but it has fallen when pooling firms from all origins. This suggests that intensified competition in international markets coexists with growing concentration among national producers.
