Agent skill stack for manuscripts targeted at Econometric Theory (ET) — the Cambridge University Press journal founded by Peter C. B. Phillips, devoted to the mathematical and statistical foundations of econometrics: asymptotic theory, probability-theoretic methods, time series and nonstationarity, and high-dimensional and non-standard environments. Papers are theorem-proof in style, with supporting lemmas, derivations, and often Monte Carlo or numerical illustration.
This repository is opinionated. It is not a generic econometrics toolbox. It is an ET-specific stack: a general, foundational result stated and proved rigorously, with defensible assumptions, clean proof exposition, simulations that show the asymptotics bite, the two-track Article / Miscellanea structure, the 50-page ceiling with overflow to the non-copyedited online Supplementary Material, single-anonymous review, and APA author-date references.
ET went through a major transition in January 2026 — new editors and a new submission system. Volatile specifics are flagged; verify them on the official journal page. Items that could not be confirmed are marked 待核实 in
resources/official-source-map.md.
ET imposes constraints that differ materially from an empirical economics journal (QJE/AER) or an applied econometrics outlet:
| Constraint | Econometric Theory | Implication |
|---|---|---|
| Contribution type | A general theory result (asymptotics, proofs, theorems) | An applied estimate with a thin theory wrapper is off-fit |
| House style | Theorem-proof, with supporting lemmas and derivations | Prose-only "results" without rigorous proof do not clear the bar |
| "Identification" | Defensible assumptions + correct limit theory, not causal design | An unstated regularity condition is the classic referee objection |
| Data/code | No mandatory archive (theory journal); voluntary Supplement only | Do not assume an AEA/JAE-style deposit applies |
| Length | Regular Articles <=50 pages; overflow → online Supplement | Pad past 50pp and it reads as undisciplined |
| Short-paper venue | Miscellanea — one or two innovations, ~15 pages | A single sharp theorem has a dedicated home |
| Review | Single-anonymous (referees see the author) | Do not double-blind-anonymize the manuscript |
| References | APA author-date | Numeric/Chicago styles read as off-template |
| Submission | ScholarOne single embedded-font PDF (since 28 Jan 2026) | Editorial Express is retired for ET |
Generic "scientific writing" or "econ writing" packs do not address these. See the constraint sources
in resources/official-source-map.md.

ectheory-workflow is the router — it tells you which skill to use next based on where you are.
| Skill | Purpose |
|---|---|
ectheory-workflow |
Router — decides which sub-skill to invoke next |
ectheory-topic-selection |
Is the result general + foundational? Article vs Miscellanea |
ectheory-literature-positioning |
Stake the theorem against the frontier (APA author-date) |
ectheory-identification-strategy |
Assumptions, regularity conditions, asymptotics, proof plan, generality |
ectheory-contribution-framing |
State the theorem so its generality is legible |
ectheory-data-analysis |
Monte Carlo / numerical illustration showing the asymptotics bite |
ectheory-tables-figures |
Size/power/coverage tables, limit-behavior plots, ET figure specs |
ectheory-writing-style |
Proof exposition, notation discipline, ET prep specs, APA references |
ectheory-replication-and-data-policy |
Reproducible computation + the online Supplementary Material file |
ectheory-review-process |
Single-anonymous review; war-game the proof-checking referee |
ectheory-submission |
ScholarOne single-PDF preflight; Article vs Miscellanea; 50-page ceiling |
ectheory-rebuttal |
Response-letter strategy for proof-checking referee reports |

- It does not write or check your proofs for you — it structures the manuscript and process
- It does not simulate any specific editor's or referee's taste
- It does not assert volatile metadata (exact fee, OA APC) — unverified items are marked 待核实
- It does not judge whether your result is genuinely general — that is the researcher's call
