Jbf Contribution Framing

---
name: jbf-contribution-framing
description: Use when sharpening the contribution claim for a Journal of Banking & Finance paper so the manuscript explains why the result matters for banking, financial intermediation, markets, regulation, or corporate finance.

# Contribution Framing (jbf-contribution-framing)

## When to trigger

- The result is statistically solid but the paper does not say why JBF readers should care
- The introduction sounds like a data exercise rather than a finance contribution
- You need a concise editor-facing pitch or cover-letter paragraph

## Contribution formula

A strong JBF contribution connects four elements:

1. **Finance problem**: the unresolved question in banking, intermediation,
   markets, corporate finance, investments, or regulation.
2. **Friction or mechanism**: information, agency, liquidity, risk, capital,
   market power, regulation, search, or behavioral channel.
3. **Credible evidence or model**: the design that lets the paper isolate the
   mechanism.
4. **Implication**: how the result changes understanding of financial institutions,
   investors, firms, or policy.

## Contribution types

- **Mechanism contribution**: identifies how a finance friction operates.
- **Measurement contribution**: creates a better measure and proves it changes inference.
- **Policy contribution**: evaluates regulation or supervisory change with credible variation.
- **Institutional contribution**: reveals bank/intermediary behavior that theory had not pinned down.
- **Theory-to-evidence contribution**: connects a formal model to a newly tested implication.

## Editor-facing paragraph

```text
We study [finance question] using [setting/design]. The key challenge is
[identification or measurement problem]. We address it by [variation/data/model],
and find [headline result with magnitude]. The paper contributes to JBF by
showing [mechanism/implication] for [banking/intermediation/markets/regulation].
```

## Anti-patterns

- Claiming contribution only because the setting is new
- Listing three literatures but not saying what each learns
- Over-selling policy relevance when the design identifies only a local effect
- Burying the magnitude until late in the paper

## Output format

```text
[One-sentence contribution] ...
[Mechanism] ...
[Why JBF] ...
[Magnitude] ...
[Boundary conditions] ...
[Next step] jbf-writing-style
