Contribution Framing, Dual Mandate (jm-contribution-framing)

When to trigger

• Results exist but the "so what" — especially the managerial one — is thin
• A reviewer or the Coeditor calls the contribution "incremental" or a "new-context replication"
• The discussion lists implications generically without a decision a manager would change
• You need to write the explicit contribution sentences for the intro and discussion

JM's contribution bar has two parts — both required

JM publishes the most impactful, thought-leading substantive research in the marketing discipline, and its mission is explicitly a bridge between the scholarly and the practical. So a JM contribution statement must do two things at once:

1. Substantive advance: a new, consequential understanding of a real marketing question — a mechanism, reversal, boundary condition, or magnitude that the field did not have. (Not "we confirmed X in setting Y.")
2. Managerial / policy / societal relevance: a concrete way managers, policy makers, consumers, or society can act differently. At JM this is a stated requirement, not a courtesy paragraph — it distinguishes JM from purely theory-driven flagships.

Write both explicitly in the introduction and revisit them in the discussion. If you can only write one, the paper is not yet a JM paper.

Defend against "incremental / new context"

For the predictable reviewer challenge, prepare a one-sentence answer to each:

• "We already knew this." → What is new, surprising, or decision-changing beyond what prior work already 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?

Make managerial relevance concrete (not boilerplate)

• Name the decision and the decision maker.
• Quantify the stake using your effect sizes in managerial units (sales lift, CLV, conversion, WTP, welfare).
• State the conditions under which the prescription holds (your boundary conditions become managerial guardrails).
• Where relevant, draw out policy or societal implications (consumer welfare, fairness, well-being, sustainability) — JM's stakeholders include policy makers and society, not only firms.

Checklist

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

Anti-patterns

• Relevance boilerplate: a generic "managers should pay attention to X" with no decision or magnitude.
• Substantive claim with no practice, or practice claim with no new insight — JM needs both.
• Contribution = method: leading with the estimator/model rather than the marketing insight.
• New-context framing dressed up as a contribution.
• Over-claiming beyond what the effect sizes and design support.
