Ecj Topic Selection

---
name: ecj-topic-selection
description: Use when scoping or framing a research question for a The Economic Journal (EJ) manuscript and you need to test whether it is "EJ-shaped" — a substantial contribution of broad interest to economists at large, full-length or short-paper. Diagnoses fit and frames the contribution; it does not design the empirics.

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

## When to trigger

- You have data or a result but not yet a sharp, broadly interesting economic question
- You are unsure whether the paper belongs at EJ, a field journal, or a top-5
- The pitch is "X is correlated with Y" with no mechanism, or a narrow result only specialists would read
- You are deciding between a **full-length article** and EJ's **short-paper (AER:Insights-style)** route

## The EJ fit test

EJ (founded **1891**, the **Royal Economic Society's** flagship, published by **Oxford University Press**; editor-in-chief **Francesco Lippi**, verified 2026-06-20) publishes the **full breadth of economics — theory and applied** — for a **broad international readership**. Its stated bar is that a paper be technically well-crafted, make a substantial contribution, and be of broad interest to economists at large. Score the idea against these five questions before committing:

1. **Broad interest** — Would an economist *outside your subfield* care about the answer? EJ's defining bar is general relevance, not just field novelty.
2. **Substantial contribution** — Does it move understanding, not just add a data point? "First to use dataset D" is not a contribution.
3. **Mechanism / economics** — Can you state the economic mechanism in one sentence, and does the paper illuminate *why*, not only *whether*?
4. **Craft** — Is the design / model technically sound enough to survive a demanding referee? Broad interest does not excuse weak identification.
5. **Exposition potential** — Can the idea be made legible to a generalist? At EJ, clear exposition is part of the contribution; an unreadable paper underperforms its substance.

If you score high on broad interest **and** substantial contribution (1 and 2) plus craft (4), it is plausibly EJ-shaped. If the idea is essentially "we ran a clean DID on niche policy P," it is a field-journal paper until you supply the general lesson and the mechanism.

## Full-length vs. the short-paper (AER:Insights-style) route

EJ explicitly welcomes **short papers in the AER:Insights style — <6,000 words and 5 exhibits** (verified 2026-06-20). Choose deliberately:

- **Short paper**: one crisp, surprising, well-identified result that needs little scaffolding; a single clean idea a generalist grasps fast. Do not pad it to full length.
- **Full-length article**: a result that needs a model, multiple designs, mechanism evidence, and counterfactuals to land; or a theory paper with developed propositions.
- A sharp self-contained finding buried inside an over-built full-length draft is often a *stronger* short paper — rescope rather than bloat.

## EJ vs. neighbors (route before drafting)

- **EJ proper**: broad relevance + clear exposition; theory and applied both core; short-paper option available.
- **The Econometrics Journal** (also RES): if the contribution is methodological/econometric with no substantive application, it fits better there.
- **JEEA / EER**: European general-interest siblings; comparable breadth — pick on fit and audience, not prestige alone.
- **Top-5**: if the result is genuinely field-moving and important, aim higher; EJ is the right home for excellent, broadly interesting work a notch below that frontier.

## Contribution framing (do this before writing the intro)

State the contribution as a numbered set of claims, each tied to economics and broad relevance:

- **Claim 1 (the economics):** what economic force / margin the paper identifies and why it was not obvious.
- **Claim 2 (the evidence or theory):** how you establish it (model result, structural estimate, or credibly identified effect).
- **Claim 3 (the broad lesson):** what the result implies beyond this setting — for theory, policy, or other fields.

## Checklist

- [ ] One-sentence question that a non-specialist economist would find interesting
- [ ] The substantial contribution stated (not a data/method "first")
- [ ] The economic mechanism written down and falsifiable
- [ ] The broad/portable lesson stated, beyond the specific setting
- [ ] Full-length vs. short-paper (AER:Insights-style) decision made and justified
- [ ] EJ vs. The Econometrics Journal / field outlet / top-5 decision made
- [ ] Contribution drafted as economic claims, not dataset novelty

## Anti-patterns

- A narrow result of interest only to one subfield — fails EJ's broad-interest bar
- An atheoretical correlation dressed up with controls and no mechanism
- Claiming novelty from a dataset rather than from an economic insight
- Padding a single clean result to full length when the short-paper route fits better
- Sending a purely methodological/econometric paper to EJ proper instead of The Econometrics Journal
- Assuming a top-5-rejected paper is automatically "EJ-shaped" without re-checking breadth and craft
