jeea-identification

name	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-model for 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 with as_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_wolf for many-outcome control.
• Sensitivity: oster_delta / sensemakr for 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).
