Research Topic Comparison Studio

Compare research topics, publication histories, and shared evidence. Missing coverage remains visible and is not treated as a zero economic outcome.

Comparison standard. Topics connect only through exact publication IDs, agenda-question IDs, issue-program IDs, dataset IDs, or route paths. Shared custody does not establish shared findings, methods, importance, legal relevance, or causation.

Comparative evidence note

What this selection establishes

Industries / Markets
01 / Common custody

3 exact items span every selected topic.

3 exact identifiers recur in two or more selected contracts. The widest pair is Industry Structure with Market Structure: 3 shared items.

02 / Coverage frontier

5 of 5 lanes appear in every selected topic.

0 structural-zero cells remain across the selected contracts. A zero records the current editorial inventory, not the absence of relevant real-world evidence.

Bar length is normalized within each row for legibility. Counts retain their own units and are never added into a score.

Publication architecture

Six permanent series footprints

Publication editions may carry more than one exact topic membership.

Comparison contract

Public questions and interpretation boundaries

Shared custody does not erase topic-specific scope.
AR-T03

Industry Structure

Which detailed industries account for broad-sector concentration patterns, and where does strict historical evidence show structural movement?
Mandate

Keep Census industry distributions, strict same-code history, business flows, and reviewed market context inspectable at their published levels.

Boundary

A NAICS industry is a statistical classification, not automatically an antitrust market. Sector medians, revenue concentration, and business dynamics retain different units and vintages.

AR-T01

Market Structure

Where is market power concentrated, how is structure changing, and which competitive mechanism still needs to be tested?
Mandate

Connect definition-bound concentration measures, participant shares, historical movement, and public research questions without collapsing unlike markets into one score.

Boundary

A concentration measure is a screen inside its stated product, geography, denominator, and period. It is not by itself proof of market power, harm, causation, liability, or the correct legal market.

Comparison boundary. Research topics are editorial navigation contracts assembled from exact publication themes and declared links to agenda questions, issue programs, datasets, and analytical routes. A topic does not create a legal market, make unlike units comparable, rank research importance, or establish market power, harm, liability, policy performance, welfare, or causation. Structural zeros remain visible as current coverage gaps.

Reproducibility contract

One selection, exact memberships, reusable rows.

The studio derives every matrix cell, edge, and register row from the same topic model published through the public data endpoint.

01

Exact join keys

Publication, agenda, issue, and dataset identifiers plus canonical route paths create the comparison ledger.

02

Visible structural zeros

Empty membership lanes remain explicit and are never imputed from adjacent research programs.

03

Portable evidence

Selected topic summaries and membership-level comparison packets are available as JSON and CSV.
