What it does
Jeea Identification is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when the identification argument is the bottleneck for a Journal of the European Economic Association (JEEA) manuscript — credible causal identification in an empirical design, parameter identification in a structural/quantitative model, or the source of identification in a theory paper. Stress-tests the strategy to JEEA's general-interest bar before exhibits are finalized.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Research & Science, covering Load testing. The repository describes itself as: Journal-specific Claude Code/Codex skill packs covering mainstream journals — AER, QJE, Nature, Cell, 管理世界, 经济研究 & 200+ more — your fast track to getting published. ｜ 覆盖主流期刊的… The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 932eb23. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Jeea Identification loads about 1.7k tokens when it runs. Until then it costs about 100 tokens; SKILL.md has 704 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- jeea-identification
- description
- Use when the identification argument is the bottleneck for a Journal of the European Economic Association (JEEA) manuscript — credible causal identification in an empirical design, parameter identification in a structural/quantitative model, or the source of identification in a theory paper. Stress-tests the strategy to JEEA's general-interest bar before exhibits are finalized.
Identification Strategy (jeea-identification)
When to trigger
- An empirical causal claim rests on OLS + controls, or TWFE on staggered timing
- A structural model's parameters are estimated but it is unclear what in the data identifies them
- A theory paper's result depends on assumptions whose role is not transparent
- You are unsure the identification clears JEEA's general-interest theory-and-empirics bar
The JEEA identification bar
JEEA spans theory and empirics, so "identification" means different things by branch — but in every case the mapping from assumptions/data to the object of interest must be explicit and defended, and credible enough for a general-interest readership and a co-editor who is not a subfield specialist. JEEA's house norms reinforce this: report standard errors and confidence sets (no significance asterisks/boldface for significance) and make the empirical strategy reproducible for the JEEA Data Editor's pre-acceptance replication check (DCAS). Pick the branch and make the argument legible.
Branch paths
Branch A: Structural / quantitative identification
- Name what identifies each parameter. Tie parameters to specific data features / moments; argue identification from the model's structure, not "the estimator converged."
- Targeted vs. untargeted moments: report fit to targeted moments and untargeted-moment validation as out-of-sample discipline.
- Sensitivity / informativeness: report parameter sensitivity to moments (sensitivity matrix) so readers see which data move which parameters.
- Estimation regularity: state the objective (MLE / GMM / MSM / indirect inference), starting values, tolerances, multi-start; report Monte Carlo evidence recovering known parameters.
- Counterfactual validity: argue the estimated parameters are policy-invariant enough for the counterfactual (Lucas critique).
Branch B: Empirical causal design (applied micro / development / finance)
- DID / event study: with staggered adoption move beyond TWFE (Callaway–Sant'Anna, Sun–Abraham, de Chaisemartin–D'Haultfœuille); show clean event-study leads; report a Goodman–Bacon decomposition.
- IV: strong first stage; with weak instruments use Anderson–Rubin / weak-IV-robust sets; defend the exclusion restriction in theory, institutions, and falsification.
- RDD: Cattaneo–Jansson–Ma density test; optimal bandwidth + robustness; covariate smoothness; bias-corrected CIs.
- Inference clustered at the assignment level; address few-cluster issues (wild-cluster bootstrap).
Branch C: Theory / mechanism identification
- What assumptions do the work. Identify the minimal assumptions driving the headline result; show which can be relaxed and which are essential.
- Comparative statics as identification: make clear which primitive moves which prediction, so the model's empirical content is testable.
- Source of the result: distinguish a genuinely new mechanism from a re-parameterization; route to
jeea-theory-modelfor generality and proof discipline.
Branch D: Experimental / own-data
- Pre-registration in a recognized registry; report deviations and the explicit estimand.
- Randomization balance; attrition (Lee bounds if differential); multiple-hypothesis adjustment; external-validity discussion.

Execution bridge (StatsPAI / Stata MCP)
Estimate and audit the design, don't only describe it. Full map:
execution-with-mcp. JEEA is a general-interest European economics flagship; credible identification across applied fields.
detect_design→recommend→ fit withas_handle=true→audit_result.- Observational causal claims: staggered DiD (
callaway_santanna/sun_abraham+bacon_decomposition+honest_did_from_result); IV (effective_f_test+anderson_rubin_ci); RDD (rdrobust+mccrary_test). - Experiments: randomization-based inference +
romano_wolffor many-outcome control. - Sensitivity:
oster_delta/sensemakrfor observational claims.
Report the magnitude in interpretable units; route the full battery to the appendix. A run end-to-end (synthetic data, real returns) is in the JF execution walkthrough.
Checklist
- Branch chosen; the assumption/data-to-object mapping stated in one sentence
- Structural: each parameter tied to identifying moments; sensitivity + Monte Carlo recovery shown
- Empirical: design-appropriate diagnostics (pre-trends / density / first-stage / balance); modern estimator where TWFE would bias
- Theory: minimal assumptions named; what is essential vs. relaxable made explicit
- Inference reported as SEs / confidence sets (no asterisks); clustering/assignment level correct
- The claim never exceeds what the identification supports
Anti-patterns
- "The estimator converged" presented as if it were identification (structural)
- TWFE on staggered treatment with no heterogeneity-bias discussion (empirical)
- A theory result whose driving assumption is hidden in notation, so its empirical content is unclear
- Calibrating parameters and running a counterfactual without arguing policy-invariance
- Reporting significance with asterisks instead of standard errors / confidence sets
Referee pushback mapped to the identification fix
- "This is OLS with controls dressed up as causal." → Provide a design (DID/IV/RDD) or a credible selection-on-observables defense with sensitivity (Oster) and falsification.
- "Staggered TWFE here is biased." → Re-estimate with Callaway–Sant'Anna or Sun–Abraham; show flat event-study leads.
- "Your structural estimates are calibration in disguise." → Show the sensitivity matrix and which moment moves which parameter; report untargeted fit.
- "The model's headline result is an artifact of one assumption." → Name the assumption, relax it, and show the result survives (or scope it honestly).
