Initial Conditions Equilibrium

Shareable calibration files for quantitative trade models

Clean, citable, and reproducible calibration artifacts. Publish .ice files for canonical models, partial tables for reuse, and the code that produces them.

Semantic versions CSV + YAML GitHub-hosted

Why .ice

Make calibration a first-class, citable asset

Standardized tables, explicit metadata, and reproducible packaging mean calibration work stops living in spreadsheets and email attachments.

Clarity

Literal tables

Long CSVs with explicit keys and a single value column. No hidden conventions or ambiguous formats.

Reproducibility

Metadata manifest

metadata.yaml records versions, timestamps, sources, and table schemas. Checksum-friendly and diff-able.

Reuse

Partial and full builds

Publish complete calibrations, partial tables (trade shares, IO, elasticities), or the scripts that produce them.

Registry

Files, tables, and code

Filter by type to find full calibrations, partial inputs, replication code, or build scripts. Toggle between list and card view.
