| name | jppm-theory-development |
| description | Use when building the conceptual backbone of a Journal of Public Policy & Marketing (JPP&M) manuscript — theorizing why a policy lever changes marketplace behavior, for whom, and with what unintended effects. Builds the theory of the lever; it does not design the studies (jppm-methods). |
Theory Development (jppm-theory-development)
When to trigger
- The paper predicts "the policy will work" without an account of why or through what
- Hypotheses ignore how firms, platforms, or intermediaries will respond to the rule
- Reviewers could ask "why would this effect differ for vulnerable consumers?" and you have no answer
- Unintended consequences (boomerang, substitution, information overload) are plausible but untheorized
- You have a mechanism story from consumer psychology but no bridge to a policy instrument
What "theory" means at JPP&M
JPP&M does not demand a novel psychological process the way JCP does, and it is not a theory-only outlet like AMR. Its bar is a theory of the policy lever: a disciplined account of how a specific instrument — a mandated disclosure, a marketing restriction, a default, a tax, an enforcement action — propagates through the marketplace to change welfare-relevant outcomes. Good JPP&M theorizing is usually middle-range: it borrows constructs from consumer research, economics of information, or regulatory-focus and protection-motivation traditions, and assembles them around the instrument. The payoff is predictions a policy analyst could not have written down: who responds, who doesn't, what the instrument's format does, and where behavior leaks around the rule.
Theorize all three sides of the exchange
A regulation touches consumers, firms, and the regulator itself. The strongest JPP&M frameworks make at least two of the three explicit:
- Consumer side — attention, comprehension, trust, reactance. Why would a warning change behavior rather than be ignored, discounted, or trigger boomerang effects (a risk long documented in the warning-label literature, e.g., Stewart and Martin 1994, JPP&M)?
- Firm side — strategic response: reformulation, repositioning, disclosure obfuscation, shifting marketing spend to unregulated channels. A rule that "works" in the lab can be neutralized in the market.
- Regulator side — instrument choice and enforcement capacity: mandated format versus safe harbor, ex ante rule versus ex post case-by-case enforcement.
From mechanism to policy-relevant hypotheses
- Make the instrument a variable, not a constant. Hypothesize over its design space (icon vs. text warning, opt-in vs. opt-out default, threshold levels), because the design space is what a regulator decides.
- Derive heterogeneity from welfare, not curiosity. The moderators that matter are the ones that define vulnerable populations — low literacy or numeracy, financial fragility, children, communities targeted by predatory marketing. "The effect is weaker for those the policy most intends to protect" is a first-order JPP&M finding.
- Predict the unintended consequence. Licensing effects of health halos, substitution to worse products, overload from disclosure proliferation, chilling of beneficial marketing. Theorizing these ex ante converts a limitation into a contribution.
- State the counterfactual logic in the theory. For evaluations: what would the outcome have been absent the policy, and why does your comparison group approximate it? The identification argument begins as a conceptual claim.
Framework archetypes JPP&M rewards
| Archetype | Contribution shape |
|---|
| Instrument-design theory | Which format/dose of the intervention works, and why (e.g., evaluative vs. numeric labels) |
| Vulnerability theory | Why a marketplace practice or policy differentially harms/protects an identified group |
| Firm-response theory | How strategic marketing reactions amplify or undo the regulation |
| Unintended-consequences theory | The behavioral pathway by which a well-meant rule backfires |
| Policy-transfer theory | Conditions under which evidence from one domain (tobacco) generalizes to another (sugary drinks) |
Checklist
Anti-patterns
- Lever-free theory: elegant consumer psychology with no instrument anyone controls
- Compliance fantasy: assuming firms implement the rule as written, with no strategic response
- Curiosity moderators: heterogeneity chosen for novelty rather than welfare relevance
- Advocacy dressed as theory: premises selected to guarantee the preferred policy conclusion
- Borrowed-framework wallpaper: invoking protection motivation or construal level as labels without deriving anything from them
Output format
【Instrument】the lever, precisely (mandate / restriction / default / tax / enforcement)
【Pathway】instrument → marketplace response → welfare outcome, step by step
【Exchange sides】consumer / firm / regulator accounts included
【Heterogeneity】which vulnerable subgroups, and the predicted direction
【Unintended consequence】the theorized backfire or leakage channel
【Next skill】jppm-literature-positioning
