What it does

Jppm Data Analysis is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when estimating and stress-testing results for a Journal of Public Policy & Marketing (JPP&M) manuscript — treatment effects from experiments, DiD/RDD/synthetic-control policy evaluations, subgroup analyses for vulnerable populations, and policy-interpretable reporting. Runs the analysis; it does not choose the design (jppm-methods).

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Data & Analytics, covering Data analysis and Load testing. The repository describes itself as: Journal-specific Claude Code/Codex skill packs covering mainstream journals — AER, QJE, Nature, Cell, 管理世界, 经济研究 & 200+ more — your fast track to getting published. | 覆盖主流期刊的… The licence is MIT.

When your agent uses it

  • Estimating and stress-testing results for a Journal of Public Policy & Marketing (JPP&M) manuscript — treatment effects from experiments
  • DiD/RDD/synthetic-control policy evaluations
  • Subgroup analyses for vulnerable populations
  • Policy-interpretable reporting

Example prompts

  • “/jppm-data-analysis”

What it can do on your machine

Read from SKILL.md and the folder at commit 932eb23. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Jppm Data Analysis loads about 1.8k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 725 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~90
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Use when estimating and stress-testing results for a Journal of Public Policy & Marketing (JPP&M) manuscript — treatment effects from experiments, DiD/RDD/synthetic-control policy evaluations, subgroup analyses for vulnerable populations, and policy-interpretable reporting. Runs the analysis; it does not choose the design (jppm-methods).

Data Analysis (jppm-data-analysis)

When to trigger

  • A DiD around a policy rollout needs modern estimators and a pre-trend defense
  • An RDD's bandwidth, density, or placebo checks are unbuilt
  • Experimental effects are significant but not yet expressed in units a regulator can use
  • Subgroup results for vulnerable populations look like fishing rather than a plan
  • A reviewer will ask "how big is this in the market, and for whom?" and you cannot answer

Estimate for the decision, not the asterisk

At JPP&M the estimate feeds a policy judgment, so the analysis has two jobs the sibling journals weigh less: (1) make the causal claim survive an econometrics-literate reviewer, and (2) express magnitudes in decision units — percentage points of prevalence, dollars per household, calories per purchase, share of consumers misled — with uncertainty attached. A p-value cannot tell an agency whether a warning is worth mandating; an effect of "−2.1 percentage points in purchase incidence, 95% CI [−3.4, −0.8], concentrated among households below median income" can. Every headline estimate should be convertible into the language of a regulatory impact analysis.

The evaluation battery

DesignCore estimateThe checks reviewers expect
DiD (staggered adoption)group-time ATTs (Callaway–Sant'Anna, Sun–Abraham)event-study plot; Goodman-Bacon decomposition; honest-DiD sensitivity to pre-trend violations
Canonical 2×2 DiDTWFE with clustered SEspre-trend test; placebo outcomes; composition stability
RDDlocal polynomial at the cutoff (rdrobust)McCrary density test; bandwidth sensitivity; covariate smoothness; donut variants
Synthetic controltreated-vs-synthetic gappre-period fit; in-space and in-time placebos; leave-one-out donors
ExperimentANOVA/OLS on manipulated conditionsrandomization/balance check; effect sizes with CIs; multiple-outcome corrections

Inference discipline: cluster at the policy-assignment level (state, market), and when treated clusters are few, use wild-cluster bootstrap or randomization inference rather than pretending N is large.

Heterogeneity as welfare analysis

Subgroup effects are not garnish here — they are often the finding. Pre-specify the policy-relevant splits (income, literacy/numeracy, age, race/ethnicity where the policy debate concerns targeting, prior usage of the harmful product), report them all rather than the flattering subset, and correct for the family of tests. An intervention with a null average effect that protects the most-exposed decile is a policy success; a positive average driven entirely by the already-safe is a policy failure. Interactions need probing (simple effects at policy-meaningful levels), and null subgroup effects deserve equivalence-style interpretation, not silence.

Translating estimates into policy terms

  • Rescale to the affected population: effect × exposed base = market-level consequence (with CI carried through).
  • Benchmark against instruments: compare the effect to what taxation, education, or existing labels achieve.
  • Report the compliance-adjusted effect: an ITT under partial firm compliance understates the mandate's potential; show both ITT and, where instruments allow, the complier-adjusted estimate.
  • Bound the unintended consequences: quantify substitution and boomerang outcomes, even (especially) when noisy.

Execution bridge (StatsPAI / Stata MCP)

Run the battery, don't just enumerate it. Full map: execution-with-mcp. JPP&M lives on policy evaluation and policy-realistic experiments; the counterfactual checks and welfare-relevant subgroup corrections are where reviewers concentrate fire.

  • detect_design → recommend → fit with as_handle=true → audit_result to enumerate what the design still owes.
  • Staggered policy adoption: callaway_santanna / sun_abraham, then bacon_decomposition and honest_did_from_result for the pre-trend sensitivity a policy audience needs.
  • Cutoff-assigned exposure: rdrobust + mccrary_test (firms sort around thresholds — test it, don't assert it).
  • Experiments and subgroup families: randomization inference plus romano_wolf / benjamini_hochberg across the vulnerable-population splits.
  • Inference with few treated clusters: wild_cluster_bootstrap; spatial policy spillovers → conley.
  • Exhibits from the handle: etable / did_summary_to_latex and plot_from_result, so table numbers never drift from the fitted model.

Keep the decisive counterfactual evidence in the body and the exhaustive battery in the web appendix; a worked end-to-end run lives in the JF execution walkthrough.

Checklist

  • Headline effects reported in decision units with CIs, not asterisks
  • DiD uses heterogeneity-robust estimators; event study + sensitivity to pre-trend violations shown
  • RDD shows density, bandwidth, and placebo checks; synthetic control shows placebos
  • SEs clustered at the assignment level; small-cluster inference handled honestly
  • Vulnerable-population subgroups pre-specified, all reported, family-corrected
  • Market-level rescaling and instrument benchmarking included
  • Unintended-consequence outcomes estimated or explicitly bounded

Anti-patterns

  • TWFE autopilot: a staggered rollout estimated with plain two-way fixed effects, no diagnostics
  • Eyeball parallel trends: a raw-trends plot standing in for a sensitivity analysis
  • Subgroup roulette: the one significant split reported, the pre-specified family hidden
  • Unitless effects: standardized betas a regulator cannot map to any decision
  • Cherry-dropped clusters: excluding inconvenient states/markets without a stated rule
  • Silent substitution: claiming success while consumers shifted to an equally harmful alternative
