description	Use when stating the contribution of a Journal of the Academy of Marketing Science (JAMS) manuscript — discharging JAMS's dual mandate of a theoretical AND a managerial contribution and defending against "incremental." Frames the contribution; it does not run the analysis (jams-data-analysis) or polish the prose (jams-writing-style).

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
