Jebo replication package

Replication & Materials Package (jebo-replication-package)

When to trigger

• The analysis is settled and you must assemble what others need to reproduce it
• An experiment is done but the instructions and z-Tree/oTree code are not yet packaged
• A referee or editor asks where the data and code are
• You are writing the Elsevier "data availability" / Research Data statement
• An agent-based model's runnable code and seeds are not yet organized for sharing

JEBO's reproducibility posture

JEBO follows the Elsevier Research Data policy: data and code sharing is strongly encouraged (via Mendeley Data or a linked repository) but not currently a hard pre-acceptance gate the way the AEA Data Editor or the Econometric Society's pre-acceptance check are (检索于 2026-06；以官网为准). In practice, for an experimental journal, referees increasingly expect the full materials, and a credible deposit strengthens acceptance. Treat the package as part of the contribution, not an afterthought.

The distinctive JEBO requirement is experimental reproducibility: a reader must be able to re-run your experiment, not just your regressions. That means the instructions, the screen-by-screen protocol, and the experiment software are first-class deposit items.

What the package must contain

Item	Detail JEBO referees look for
Experiment instructions	full participant-facing text (translated to English if run in another language), including comprehension questions
Experiment software	z-Tree .ztt / oTree app code, or the platform code, runnable with setup notes
Screenshots / protocol	session protocol, screen flow, randomization procedure, payment scheme
Raw data	subject-level raw output (anonymized), with a codebook
Analysis code	scripts that go from raw data to every table/figure, with a master run file
Software environment	versions (Stata/R/Python, z-Tree/oTree), packages, seeds for any simulation
README	one-command (or clearly-ordered) reproduction path; maps each script to each exhibit
Pre-registration link	registry URL + a note on deviations, if pre-registered
Ethics / consent	IRB/ethics approval reference; consent procedure

For agent-based / simulation papers, the deposit is the model code, parameter files, seeds, and the sweep scripts that regenerate the reported figures.

Privacy and anonymization

Strip direct identifiers from raw subject data; for field data, follow consent and data-protection constraints and document any access restrictions. State clearly if data cannot be shared and why (Elsevier allows a justified restricted-access statement).

The data-availability statement

Write the Elsevier "Data availability" statement to match reality: a Mendeley Data DOI / repository link, or a justified statement of restriction. Vague statements ("data available on request") are weak and increasingly disfavored; deposit where possible.

Checklist

• Experiment instructions (English) + comprehension questions included
• z-Tree/oTree or platform code included and runnable, with setup notes
• Session protocol, screen flow, randomization, and payment scheme documented
• Raw subject-level data (anonymized) + codebook
• Analysis scripts reproduce every table/figure from raw data via a master file
• Software versions, packages, and seeds recorded
• README maps each script to each exhibit; reproduction path is explicit
• Pre-registration link + deviations noted (if applicable); IRB/consent referenced
• Data-availability statement points to a real deposit (Mendeley Data) or a justified restriction

Anti-patterns

• Sharing analysis code but not the experiment software/instructions (cannot re-run the experiment)
• "Data available on request" with no deposit
• Raw data with direct identifiers left in
• A README that lists files but never gives the reproduction order
• Simulation results with no seeds or sweep scripts
• Claiming pre-registration without linking the registry or disclosing deviations
