Corporate concentration
The dominance of economic activity by a small number of very large firms—often discussed alongside, but not identical to, statistical market concentration.
Corporate concentration highlights power in product, labor, and political arenas: a few employers may set wages regionally; a few platforms may control digital gateways; a few manufacturers may anchor supply chains.
The P2 list in the economists-hour content plan treats corporate concentration as its own watchword, tied especially to future state_industry views of sectors and chains.
Relation to market concentration
Market concentration indices summarize sales shares; corporate concentration narratives also stress governance, lobbying, and investment behavior. Both feed antitrust and industrial-policy debates.
