Ecta Tables Figures

Tables and Figures (ecta-tables-figures)

When to trigger

• A Monte Carlo or empirical table is overloaded, ambiguous, or not self-contained
• Notes do not say what is being reported (size? coverage? bias?) at what sample size and nominal level
• Figures (power curves, coverage plots, value-function illustrations) lack axis labels or a legend
• Numbers in the table cannot be traced to a specific script / seed

Econometrica exhibits are read closely by referees who will recompute or sanity-check entries — and at conditional acceptance the ES Data Editor re-runs the code behind every table, figure, and number that comes from data or simulation. Every table and figure must stand alone and trace to a seeded script in the replication package. Two Econometrica specifics that differ from applied siblings: (1) the 45-page main-text limit (incl. references and appendices) forces ruthless triage — keep the headline size/power/coverage tables in the body and push secondary designs to the Supplemental Material; (2) reproducibility is enforced by the Econometric Society Data Editor with a Zenodo deposit, not the AEA/openICPSR pipeline the AER/AEJ packs assume.

Simulation-table standards

1. Self-contained. The caption + notes must let a reader interpret every number without the body text: estimator(s), DGP / design, sample size(s), number of replications, nominal level, and what each column reports (bias, RMSE, empirical size, coverage, length).
2. One concept per table where possible — do not mix size, power, and point-estimation quality in one undifferentiated block.
3. Consistent precision. Choose decimal places deliberately (e.g., sizes to 3 decimals so 0.052 vs. 0.048 is visible) and keep them consistent down a column.
4. Highlight the comparison. The reader should see at a glance that the proposed method controls size / has lower RMSE than the competitor — order columns/rows so the contrast reads.
5. Monte Carlo error. Where a size or coverage near the nominal level carries the argument, make the simulation precision clear (replication count in notes, or a reported MC standard error).
6. Three-line / booktabs style. Clean rules (top, mid, bottom), no vertical lines, no shading — the standard for formal economics journals.

Figures

• Label everything: axes with units, every series, the nominal-level reference line on a size/coverage plot, the null on a power curve.
• Power curves: plot rejection probability against the departure parameter; mark the null and the nominal level; use size-adjusted curves for fair comparison.
• Coverage plots: show coverage across designs / sample sizes against the nominal target.
• Theory illustrations: equilibrium / value function / comparative statics across the parameter range, with the relevant region annotated.
• Vector format (PDF/EPS) so curves stay crisp; legible at print size; colorblind-safe and readable in grayscale.

Traceability

• Each table/figure should be regenerated by a named script with a fixed seed (tie this to ecta-replication-package). Keep a map: Table N ↔ script ↔ seed ↔ output file.
• Numbers in the text must match the tables exactly (no rounding drift between prose and table).

Execution bridge (StatsPAI / Stata MCP)

Generate exhibits from the fitted result, not by retyping numbers. Full map: execution-with-mcp. Econometrica publishes econometric theory and applied micro; the chain below serves its applied/empirical papers (weak-IV-robust and modern-DiD reporting expected) — pure theory uses its own apparatus.

• Tables: etable (multi-model) or did_summary_to_latex straight from the result_id.
• Figures: plot_from_result / enhanced_event_study_plot / event_study_table — axis units and the SE/clustering note baked in.
• Every note names the estimator + clustering and states the magnitude in interpretable units.

Checklist

• Caption + notes make each exhibit fully self-contained
• DGP/design, n, replications, nominal level, and per-column meaning all stated
• Decimal precision deliberate and consistent
• Competitor methods included; the key comparison reads at a glance
• Monte Carlo precision conveyed where size/coverage carries the argument
• Three-line / booktabs style; no vertical rules or shading
• Figures fully labeled; vector format; readable in grayscale
• Every exhibit traces to a named script + seed; text numbers match tables

Anti-patterns

• A size table with no nominal level stated, so 0.07 is uninterpretable
• Mixing size, power, and bias in one block with no clear separator
• Reporting power without indicating size, making the method look artificially good
• Inconsistent decimals down a column, hiding the comparison
• A figure with unlabeled axes or an unexplained second series
• Numbers in the text that disagree with the table by a digit
• A table no script can regenerate, so replication review cannot verify it
