# Contribution Framing, Dual Mandate (jams-contribution-framing)

## When to trigger

- Results exist but the "so what" — especially the managerial one — is thin
- A reviewer or editor calls the contribution "incremental" or a "new-context replication"
- The discussion lists implications generically with no decision a manager would change
- You need to draft the explicit contribution sentences for the intro and discussion

## JAMS's contribution bar has two parts — both required

JAMS exists to **advance the science and practice of marketing**. That dual purpose is structural, not rhetorical: a JAMS contribution statement must do two things at once, and the paper is incomplete if either is missing.

1. **Theoretical contribution.** A *new, consequential* understanding of a marketing relationship — a mechanism, a contingency/boundary condition, a reconciliation of competing frameworks, or a validated construct the field lacked. Not "we confirmed X in setting Y."
2. **Managerial contribution.** A concrete way a marketer, sales leader, channel partner, or policy maker can act differently. At JAMS this is **expected and weighted**, not a courtesy paragraph — it is the journal's historic identity and a frequent point of reviewer pushback.

Write both explicitly in the introduction and revisit both in the discussion. If you can only write one, the paper is not yet a JAMS paper. A theory-only paper drifts toward the modeling/consumer siblings; a managerial-only paper reads as a trade article.

## Make each contribution concrete

**Theoretical:**
- State what the field *could not explain or predict* before this paper.
- Tie it to your mechanism (mediator) and contingencies (moderators), not just a significant main effect.

**Managerial:**
- Name the **decision** and the **decision maker**.
- Quantify the stake in **managerial units** using your effect sizes (sales lift, share, CLV, margin, retention, WTP, brand-equity points, firm value).
- State the **conditions** under which the prescription holds — your boundary conditions become managerial guardrails and segmentation rules.
- Where relevant, extend to **policy / societal** stakes (consumer welfare, sustainability, well-being).

## Defend against "incremental"

Prepare a one-sentence answer to each predictable challenge:

- *"We already knew this."* → What is new, surprising, or decision-changing that prior work could not have told us?
- *"You just changed the setting."* → What about the **mechanism, magnitude, or boundary** is genuinely different — not merely the industry/country/platform?
- *"So what for practice?"* → Which decision changes, for whom, and how large is the gain in managerial units?

## Diagnose which type of theoretical contribution you have

Naming the *type* of advance sharpens the claim and tells the reviewer how to judge it:

- **New mechanism** — you identify and test the process (mediator) carrying a known effect.
- **New contingency** — you bound a known effect, showing when it strengthens, weakens, or reverses (a moderator).
- **Reconciliation** — you resolve a contradiction between two literatures or two prior findings.
- **New construct / measure** — you conceptualize and validate something the field could not previously measure.
- **New magnitude / fact** — you credibly quantify, for the first time, a relationship the field had only assumed.

A JAMS paper usually rests on one of these as its primary claim; trying to claim all five at once dilutes the contribution and invites the "overclaiming" critique.

## Write the four contribution sentences

Draft these explicitly and reuse them verbatim in the intro and discussion:

1. *Theoretical:* "We contribute to [stream] by showing that [mechanism/contingency], which prior work could not [explain/predict]."
2. *Managerial:* "For [decision maker] facing [decision], our results imply [action], worth roughly [magnitude in managerial units] under [condition]."
3. *Boundary/guardrail:* "This holds when [moderator]; managers should not apply it when [reversal condition]."
4. *Scope of the claim:* "We do not claim [overreach the design cannot support]."

If sentence 1 or 2 will not write, the paper is not yet a JAMS paper; if sentence 4 is hard, the claim is probably overreaching.

## Checklist

- [ ] One-sentence theoretical contribution (new, consequential understanding) written
- [ ] One-sentence managerial contribution (decision changed, quantified) written
- [ ] Both appear in the introduction and are revisited in the discussion
- [ ] Managerial stake quantified in real units, with conditions/guardrails
- [ ] "Incremental / new-context" challenge answered explicitly
- [ ] Policy/societal angle addressed where the question warrants
- [ ] Contribution does not rest on methodological novelty alone

## Anti-patterns

- **Relevance boilerplate**: "managers should pay attention to X" with no decision or magnitude
- **Theory without practice**, or **practice without new insight** — JAMS needs both
- **Contribution = method**: leading with the estimator/model instead of the marketing insight
- **New-context framing** dressed up as a contribution
- **Over-claiming** beyond what the effect sizes and design support

## Output format

```text
【Theoretical contribution】[one sentence: new, consequential understanding]
【Managerial contribution】[one sentence: decision changed + magnitude in managerial units]
【Both in intro + discussion】yes/no
【Quantified stake】lift / share / CLV / WTP / firm value = [...]; conditions: [...]
【Incremental/new-context defense】[...]
【Policy/societal angle】[...] / NA
【Next skill】jams-tables-figures
```
