name: rje-topic-selection
description: Use to test whether a research question fits The RAND Journal of Economics (RJE) — the flagship industrial-organization journal with a deliberately narrow applied-microeconomics scope (regulated industries, antitrust/competition, market structure, firm strategy, the economics of organizations). Screens fit before you invest in a full draft.

# Topic Selection & Fit (rje-topic-selection)

## When to trigger

- Deciding whether RJE is the right home for an applied-micro project
- A project drifting toward general theory or macro and you need a scope check
- Sharpening a vague firm/market question into an IO-flagship-worthy one

## The RJE scope (verified 2026-06-01)

RJE exists, per its own statement of purpose, "to support and encourage research in the **behavior of regulated industries, the economic analysis of organizations, and more generally, applied microeconomics**" (rje.org). Formerly the **Bell Journal of Economics** and sponsored by the **RAND Corporation**, it is widely regarded as **the field's flagship industrial-organization journal**. The scope is **deliberately narrow** — it is *not* a general-interest, methods, or macro outlet. **Both theoretical and empirical** IO work is welcomed.

## On-scope topics (strong fit)

- **Competition / antitrust:** market power, mergers, collusion, exclusion, vertical relationships.
- **Regulated industries:** electricity, telecom, transportation, health insurance, networks, and the design/effects of regulation.
- **Market structure & firm strategy:** entry/exit, pricing, product differentiation, advertising, platforms, two-sided markets.
- **Economic analysis of organizations:** contracts, incentives inside firms, vertical integration, the boundaries of the firm.
- **Auctions and mechanism design** with a market/competition application; related **law-and-economics**.

## Off-scope (route elsewhere)

- General economic theory or macro with no IO/market mechanism — wrong journal.
- Labor/public/development questions with no industrial-organization core (those fit general-interest or field journals, not the IO flagship).
- Pure methodology with no substantive market question.

## The RJE bar

A strong RJE topic poses a **first-order question about how a market or firm works**, answers it with a **structural model or a credible reduced-form design**, and delivers a **competition, regulation, or welfare lesson**. Because the journal's identity is IO, a sharp market mechanism beats a broad-but-vague theme. The hard page caps (40/50 pp) also reward focused questions over sprawling ones.

## Fit-screening grid (does the question belong at the IO flagship?)

Run the candidate question through the grid before committing months to a draft. A strong RJE topic clears every column.

| Question trait | Strong fit | Borderline | Route elsewhere |
|---|---|---|---|
| Core mechanism | Competition, regulation, firm strategy, organizations | Market-adjacent but mechanism unclear | No market/firm mechanism |
| Object identified | Demand/cost primitive, conduct, entry, welfare | A reduced-form effect with IO stake | A correlation with no IO stake |
| Policy payoff | Antitrust/regulation/welfare lesson | Lesson present but thin | None |
| Scope | One sharp question inside 40 pp | Two-question agenda | Sprawling, multi-topic |
| Method available | Structural model or credible design | Design exists but contested | No credible design |

## Worked vignette: rescuing a borderline question

Suppose the initial idea is "do online reviews affect restaurant revenue?" — interesting, but as stated it is a general applied-micro correlation, borderline-to-off-scope for the IO flagship. Sharpen it toward an IO mechanism:

- **Add a market-power angle**: reframe as "do platform-displayed reviews soften or intensify price competition among nearby restaurants?" — now the object is competitive conduct, squarely IO.
- **Name a structural object**: the question becomes whether review salience shifts demand elasticities and thus equilibrium markups.
- **State the policy payoff**: implications for platform design and for whether rating systems are pro- or anti-competitive — relevant to competition authorities.
- **Scope it**: one market (one city's restaurants over one platform redesign), one mechanism, comfortably inside the page cap.

The rescued version poses a first-order question about how a market works and delivers a competition lesson; the original did neither.

## Calibration anchors (what an on-scope RJE article looks like)

- A single market or closely related set of markets, not a cross-country panel of everything.
- A structural model or a clean design built around an identified competition/regulation mechanism.
- A welfare or policy verdict that an antitrust authority or regulator could act on.
- These are general patterns, not quotas — confirm current emphases against recent issues and the journal's statement of purpose.

## Anti-patterns

- Pitching a general-micro or macro paper as "applied microeconomics" with no market mechanism
- A reduced-form correlation with no competition/regulation/organization stake
- A project too broad to argue inside the 40-page main-text cap

## Output format
