Policy thesis

National competition policy needs a shared evidence infrastructure that preserves market definition, geography, vintage, and procedural posture instead of compressing unlike signals into one score.

Public asks

Publish a recurring competition data inventory

Coordinate agency releases across industry concentration, state markets, merger activity, and enforcement records with stable identifiers, machine-readable tables, and documented update schedules.

Pair screens with exact analytical scope

Every public concentration statistic should travel with its product or industry universe, geography, denominator, vintage, source status, and residual-category treatment.

Turn missing shares into disclosure priorities

Prioritize firm-level public reporting where essential markets remain visible only through aggregate shares, usage proxies, or local ownership fragments.

Source basis

2022 and 2017 U.S. Economic Census industry concentration tables, USDA ERS historical meatpacking CR4, KFF 2024 state individual-market HHI, FDIC 2025 statewide and county Summary of Deposits screens, the FY2025 FTC/DOJ HSR report, and source-backed market and enforcement records.
