Tables & Figures (jhr-tables-figures)

When to trigger

• Results are ready but tables are dense or over the page limit
• You need reconciliation, robustness, or design diagnostics in exhibit form
• The Online Appendix needs a clear structure

Exhibit plan

• Table 1: sample, descriptive statistics, and key balance where relevant.
• Main table: preferred specification with transparent controls and clustering.
• Design diagnostic: pre-trends, first stage, manipulation, balance, or event study depending on design.
• Reconciliation table: compare your estimate to prior estimates and explain the bridge.
• Appendix: robustness, sensitivity, alternative samples, and extra outcomes.

Notes must state

• Unit, sample, period, outcome units
• Fixed effects and controls
• Clustering level
• Treatment definition
• Survey weights or population weights if used
• Page/appendix location

Main-text exhibit budget

Use the scarce main-text pages for exhibits that change a reader's belief:

1. Sample and balance: proves the population and comparison are understandable.
2. Main estimate with magnitude: preferred result plus units and confidence interval.
3. Design diagnostic: pre-trend, first stage, manipulation test, balance, or attrition.
4. Reconciliation: prior estimate vs. your bridge specification vs. preferred specification.
5. Policy heterogeneity: only if it maps to a real policy margin, not a fishing cut.

Everything else belongs in the Online Appendix with clear cross-references.

Appendix map

Organize appendix exhibits by reviewer use, not by the order scripts happen to run:

• Design validity: balance, pre-trends, manipulation, attrition, first stage, or placebo evidence.
• Specification sensitivity: alternative controls, bandwidths, estimators, samples, weights, and clustering levels.
• Reconciliation: bridge specifications that explain differences from prior estimates.
• Mechanism and heterogeneity: only after the main effect and design validity are clear.
• Data construction: variable definitions, sample filters, merges, missingness, and coding decisions.

Each appendix table should be referenced from exactly one main-text claim or robustness sentence. Orphaned appendix exhibits create page and credibility costs.

Event-study figure standard

The event-study plot is often the single most scrutinized exhibit in a JHR design paper. Hold it to this bar:

• Name the estimator in the note (heterogeneity-robust group-time aggregation, interaction-weighted, or imputation — not just "event study").
• Reference period marked (usually t = -1) and at least four pre-periods shown when the data allow; binned endpoints labeled as bins.
• 95 percent confidence intervals from SEs clustered at the assignment level, with the cluster count in the note.
• Y-axis in outcome units, not standardized indices, so the policy reader can judge magnitude directly.
• If TWFE and robust estimates diverge, plot both series rather than choosing silently.

First-stage and RD display conventions

• IV papers: a first-stage table adjacent to the 2SLS table — coefficient, effective F per endogenous regressor, and the reduced form; referees read these three together.
• RD papers: the binned outcome plot and the density plot are a pair; show the bandwidth on the figure and put manipulation-test results in the note.
• Lottery papers: a balance exhibit within randomization strata precedes any effect figure.

Worked exhibit ledger

Illustrative ledger for a childcare-subsidy DID paper (titles invented):

Fig 1  Rollout map + timing of county adoption          claim: variation exists
Tab 1  Sample means, adopters vs not, pre-period        claim: comparability
Tab 2  ATT on maternal employment, 3 estimators         claim: main effect
Fig 2  Event study, 5 pre / 6 post, CIs, clusters=42    claim: no pre-trends
Tab 3  Bridge to prior state-level estimate             claim: reconciliation
Tab 4  Heterogeneity by single-parent status            claim: policy margin
App A  Sensitivity: windows, controls, clustering       referenced from Tab 2

Seven main exhibits is a sensible ceiling under the page cap; every appendix entry must be cited from one main-text sentence.
