We document a novel relationship between networks of firms linked through ownership (i.e., business groups) and labor income using matched employer-employee data for Chile. Business group affiliation is associated with higher wages, even after controlling for firm size and individual worker effects. The group premium is stronger for top workers; hence, group firms have higher wage dispersion. The premium remains present when comparing group firms and matched stand-alone firms, and in within-firm comparisons using transitions in and out of groups. Our results are consistent with workers reaching higher productivity and wages by leveraging their skills on the group’s organizational structure.
