Jmcb Tables Figures

Tables and Figures (jmcb-tables-figures)

When to trigger

• An IRF figure has bands but no statement of what shock, what units, or what horizon
• A regression table reports six columns and the reader cannot tell which is the headline
• A bank balance-sheet or summary table is a data dump with no economic grouping
• Significance is shown with asterisks alone, with no economic magnitude in view
• The paper is at the 40-page limit and exhibits are competing for space with text

The JMCB exhibit bar

JMCB is a quantitative monetary/banking journal, so its signature exhibits are impulse-response functions, local-projection coefficient plots, and event-study figures, alongside the standard regression and balance-sheet tables. The bar is that each exhibit is self-contained and economically legible: a reader skimming should grasp the shock, the units, the horizon, the magnitude, and the uncertainty without hunting through the text. Because the journal recommends ≤40 pages including tables and figures, exhibit economy is also a length discipline — every panel must earn its place.

Exhibit craft

Impulse responses and local projections

• Label the shock and its size ("response to a 25bp contractionary surprise") and the units of the response (pp, %, bps) directly on the figure.
• Show confidence bands and state the method in the note (bootstrap/HAR/lag-robust). For local projections, show enough horizon to see the peak and the return.
• Put the economic magnitude in the caption, not only the plot — "lending falls 1.8% at the 4-quarter peak."

Regression and panel tables

• Headline column first or visually flagged; do not make the reader guess which specification is the result.
• Report the economic magnitude (a one-SD or one-policy-unit effect) next to the coefficient — a deposit beta or a pass-through in interpretable units, not a bare coefficient.
• State fixed effects, clustering, and N in every table; for micro-banking, make the firm×time absorption visible so demand-netting is obvious.
• Significance via asterisks is acceptable in JMCB house style, but never let asterisks substitute for magnitude — the economic size must be readable.

Balance-sheet / summary tables

• Group rows by economic meaning (funding, lending, capital, liquidity), not source order.
• Show the cross-section that matters for the mechanism (e.g., by capital quartile) rather than one pooled column.

The exhibit hierarchy a referee reads first

Referees skim exhibits before prose. Order them so the argument is legible from the figures and tables alone:

1. A descriptive/summary table or motivating figure — establishes the sample and the variation (e.g., the cross-section of bank capital, the time series of the shock).
2. The headline exhibit — the IRF, the main coefficient table, or the counterfactual that is the contribution. It should be unmistakable.
3. The mechanism exhibit — the heterogeneity cut or channel decomposition that shows why (e.g., response by capital quartile).
4. The key robustness exhibit(s) — the one or two that defuse the most damaging objection, with magnitudes beside the baseline.

If a referee can reconstruct the paper's claim from this sequence without the text, the exhibits are doing their job.

Notes, units, and reproducibility cues

Table and figure notes are not decoration at JMCB — given the journal's replication heritage, they are where a careful referee checks that the exhibit means what the text claims. Each note should state the sample period and frequency, the estimator, the inference method (clustering dimensions, bootstrap, HAR), and the units of the reported effect. For IRFs, state the shock normalization explicitly (a 25bp or one-SD surprise). Ambiguous units or missing inference details invite the referee to assume the worst.
