Data sources

Core inputs for calibrations

Trade

BACI

Product-level bilateral trade (HS6). Source: CEPII BACI (Gaulier & Zignago, 2010). Link

IO tables

OECD ICIO

Inter-Country Input-Output Tables. Link

Tariffs

WTO IDB

Applied tariff data by HS code. Link

Concordances

Harmonize sectors across sources

Keep mappings versioned and cited. Include them in metadata and build scripts.

HS6 to ISIC Rev.4

Use official UN/Eurostat concordances or CEPII mappings. Document the release year and coverage.

ISIC Rev.4 to GTAP/WIOD

Map sector codes for IO and tariff alignment. Keep mapping tables as CSV within your .ice build scripts.

Tooling

icetools and helpers

R package to generate, validate, and inspect .ice files.

icetools (R)

github.com/julianhinz/icetools

  • create_metadata(), generate_ice(), validate_ice()
  • Helpers for reading/writing long tables and computing checksums
  • Works with CSV + YAML only. Easy to embed in pipelines.

Templates

Starter scripts and concordance utilities live in the library repo (scripts/template, scripts/concordances). Copy, adapt, and contribute back.
