Comparability ruleA visible difference becomes analytical evidence only inside a declared common frame.Audit the rule
Question-led comparison router
Start with the claim you need to test.
Each route carries its own unit, population, period, source, and exclusion rule into the analytical workspace.Current research frame Markets2 comparison systems
Definition-aware market screens
How does measured market structure differ?
Compare concentration screens or exact indicator pairs without treating unlike market definitions as one population.Recommended starting instrumentMarket comparison studio
Compare two to four market profiles while every product boundary, geography, denominator, year, and disclosure gap remains visible.

Comparability passport
What travels with this comparison
- Unit
- Profile-native HHI, CR4, shares, and declared indicators
- Alignment
- Definition, entity, period, denominator, and source
- Output
- Screens, histories, paired planes, and coverage diagnostics
- Never inferred
- No cross-market average or synthetic market-power score
