Writing Style (jpam-writing-style)
The JPAM house voice is clear, calibrated, and decision-oriented. A JPAM paper earns its place by
stating a policy implication the design actually supports — neither buried in hedges nor inflated
beyond what was identified. Write for a reader who may be an economist, a political scientist, a public-
management scholar, or a practitioner, and who wants to know: what did you find, how credible is it, and
what should we do about it.
When to trigger
- Drafting the abstract, introduction, or the policy-implications / conclusion section
- A reviewer said the paper "overclaims," "buries the finding," or "isn't legible to non-economists"
- Calibrating the strength of the policy recommendation to the evidence
- Tightening jargon for the cross-disciplinary APPAM audience
The JPAM introduction arc
Policy problem & decision → what's known and the gap → the policy/program studied → the credible design (named as a tool) → the headline effect in policy units → the cost-benefit / distributional takeaway → the calibrated implication → brief roadmap. The reader should know the finding and what it means for
policy by the end of the first page.
Calibrated implication (the JPAM signature)
-
State the implication, then bound it. "This program raised Y by Z; at a cost of C per recipient,
the benefit-cost ratio is R" — followed by the scope conditions that govern whether it transfers.
-
Match the verb to the design. A local RD estimate supports a claim about the threshold population,
not the whole eligible pool. An ITT supports a claim about offering the program, not receiving it.
-
Say what you cannot conclude. Naming the limits is persuasive at JPAM, not weak; an honest
boundary protects the credible core from the overclaiming critique.
-
No policy advocacy beyond the evidence. Recommend within what the estimate, cost-benefit, and
external-validity conditions support.
Cross-disciplinary legibility
- Define field-specific jargon; do not assume the econ, PS, or PA reader shares your vocabulary.
- Lead with substance over method; the estimator is a tool, not the headline.
- Keep the abstract concrete: question, policy/program, design, finding, implication.
Checklist
Anti-patterns
- Overclaiming: a sweeping policy recommendation from a local or imprecise estimate
- The opposite failure: burying a credible finding under so many hedges no implication survives
- Leading with the estimator instead of the policy question and finding
- Field jargon that locks out the other APPAM disciplines
- A conclusion that pivots to advocacy the evidence does not license
- An abstract that names the method but never the policy takeaway
Overclaim vs. calibrated (illustrative contrasts)
-
Overclaim: "Our results show that this program should be adopted nationwide." → Calibrated:
"Among the threshold population our RD identifies, the program raised Y by Z at a benefit-cost ratio of
R; whether this extends to the full eligible pool depends on [scope condition]."
-
Overclaim: "The policy works." → Calibrated: "Offering the program (ITT) raised Y by Z;
because take-up was T%, the effect on participants is larger but less precisely estimated."
-
Over-hedged (the opposite failure): burying a credible effect under so many caveats that no
implication survives — JPAM wants the calibrated claim stated, not dissolved.
Calibration anchors (hedged)
- At JPAM, naming what you cannot conclude strengthens the paper — it is the credibility that earns the
policy recommendation you can make.
- The Point/Counterpoint forum aside, JPAM is not an advocacy outlet; recommendations live inside the
envelope of the estimand, the cost-benefit result, and the external-validity conditions.
- Write the abstract so a policymaker learns the finding and the takeaway; a method-only abstract
misses JPAM's audience.
