Understanding HHI
The Herfindahl-Hirschman Index (HHI) measures market concentration by summing the squares of product shares. Values below 1,500 indicate unconcentrated markets, 1,500-2,500 moderate concentration, and above 2,500 high concentration. A perfectly competitive market would have an HHI near 0, while a monopoly would approach 10,000.
