--- name: jebo-identification description: Use when the design that isolates a behavioral mechanism is the bottleneck for a Journal of Economic Behavior & Organization (JEBO) manuscript — lab/field experiment, observational causal design, or simulation. Stress-tests experimental and observational identification to JEBO's behavioral-credibility bar; it does not write prose or build the deposit. --- # Identification Strategy (jebo-identification) ## When to trigger - A lab/field experiment's treatment, incentives, or comprehension are not pinned down - An effect could be an **experimenter-demand effect** rather than the claimed behavioral mechanism - An observational behavioral claim rests on OLS + controls, or TWFE on staggered timing - A study uses deception, or runs many treatments, and the inference/ethics implications are unaddressed - You are unsure the design isolates the *behavioral* mechanism, not a confound ## The JEBO identification bar JEBO judges identification through a **behavioral-mechanism** lens: the design must isolate the *psychological or institutional channel* the paper claims, not merely produce a significant difference. Because JEBO treats **experimental design as a first-class identification branch** alongside observational causal designs, "identification" means different things by branch — pick the branch and make the channel transparent. Inference must match the design (clustering at the level of randomization or assignment; few-cluster corrections). ### Branch A: Lab / online experiment (the JEBO core) - **Incentive compatibility:** payoffs must make truthful/effortful behavior the dominant strategy for the elicited object (e.g., BDM, strategy method, incentivized beliefs). State the mechanism and the stakes. - **No-deception norm:** the experimental-economics convention is **no deception**; if you deviate, justify it and expect scrutiny — many referees treat deception as disqualifying for an incentivized study. - **Comprehension & attention checks:** report comprehension quizzes, control questions, and how failures were handled (drop / re-instruct), so the effect is not confusion. - **Experimenter demand:** rule out demand effects — neutral framing, between-subject where within-subject would cue the hypothesis, obfuscated objectives, or an explicit demand-treatment (e.g., Mummolo–Peterson / de Quidt-style bounds). - **Randomization & balance:** show balance on observables; report the randomization procedure and unit. - **Multiple treatments:** if several treatment arms, plan the comparisons and correct for multiplicity (see jebo-robustness). - **Pre-registration:** pre-register the design and primary analysis (AEA RCT Registry / AsPredicted / OSF) and report deviations. (JEBO does not currently mandate it — 待核实 — but referees increasingly expect it.) ### Branch B: Field experiment - ITT vs. LATE/TOT stated; randomization unit and stratification described; spillovers and SUTVA addressed. - Attrition examined and bounded (Lee bounds if differential); compliance documented. - Ethical clearance / consent noted; external-validity scope stated (the field setting's generality). ### Branch C: Observational behavioral empirics - **DID / event study** with staggered adoption: move beyond TWFE (Callaway–Sant'Anna, Sun–Abraham, de Chaisemartin–D'Haultfœuille); show clean event-study leads; Goodman-Bacon decomposition. - **IV:** strong first stage (effective F); weak-IV-robust sets (Anderson–Rubin) when needed; defend exclusion in institutions/theory + falsification. - **RDD:** density/manipulation test (McCrary / Cattaneo–Jansson–Ma); local-linear, data-driven bandwidth, bias-corrected robust CIs. - The behavioral interpretation must be argued, not assumed — the design identifies an estimate; the *mechanism* connecting it to a behavioral channel needs its own evidence (see jebo-theory-model). ### Branch D: Agent-based / simulation - Document the data-generating process and behavioral rules; set and report seeds; show the result is not an artifact of grid/tuning choices (see jebo-robustness). ## Execution bridge (StatsPAI / Stata MCP) Estimate and audit the design, don't only describe it. Full map: [`execution-with-mcp`](../../../shared-resources/empirical-methods/execution-with-mcp.md). JEBO spans behavioral/experimental and applied micro; randomization inference for experiments, DiD/IV for observational claims. - `detect_design` → `recommend` → fit with `as_handle=true` → `audit_result`. - **Observational causal claims:** staggered DiD (`callaway_santanna` / `sun_abraham` + `bacon_decomposition` + `honest_did_from_result`); IV (`effective_f_test` + `anderson_rubin_ci`); RDD (`rdrobust` + `mccrary_test`). - **Experiments:** randomization-based inference + `romano_wolf` for many-outcome control. - **Sensitivity:** `oster_delta` / `sensemakr` for observational claims. Report the magnitude in interpretable units; route the full battery to the appendix. A run end-to-end (synthetic data, real returns) is in the [JF execution walkthrough](../../../Journal-of-Finance-Skills/resources/worked-examples/02-execution-walkthrough.md). ## Checklist - [ ] Branch chosen; the design-to-mechanism mapping stated in one sentence - [ ] Experiment: incentive-compatible elicitation; no deception (or justified); comprehension checks reported - [ ] Experimenter-demand effects ruled out or bounded - [ ] Randomization unit, balance, and (for field) attrition/spillovers handled - [ ] Observational: design-appropriate diagnostics; modern estimator where TWFE/2SLS would bias - [ ] Inference clustered at the randomization/assignment level; few-cluster issue addressed - [ ] The behavioral claim never exceeds what the design isolates ## Anti-patterns - Reporting a treatment difference as a behavioral mechanism without ruling out demand effects - Using deception in an incentivized study without justification (referees may reject outright) - Within-subject designs that cue the hypothesis, presented as if between-subject-clean - TWFE on staggered treatment with no heterogeneity-bias discussion - Calling a significant coefficient "evidence of [bias]" when a non-behavioral confound survives - Significance asterisks standing in for clustered SEs or a pre-registered primary outcome ## Worked vignette (illustrative) A lab study claims that public visibility raises cooperation via image concerns. A referee asks whether subjects merely inferred the experimenter wanted more cooperation in the visible arm. The JEBO fix: add a demand-effect treatment (explicitly tell one cell "we expect more cooperation"), show the visibility effect (illustrative: +0.6 contributions, s.e. 0.2) is an order of magnitude larger than the pure demand response, and pre-register cooperation as the primary outcome — turning "could be demand" into a bounded, mechanism-level claim. ## Output format ```text 【Branch】lab / field / observational / simulation 【Design-to-mechanism mapping】one sentence 【Behavioral channel isolated】 【Identification evidence】[incentives+comprehension+demand-bound / balance+attrition / pre-trends+density+first-stage / DGP+seeds] 【Estimator + inference】estimator; clustering level; weak-IV/honest-DID if any 【What it does NOT identify】[...] 【Next step】jebo-theory-model ```
