Imports

JCGE provides two import paths: data ingestion and MPSGE model conversion. The goal is to make external data and legacy model structures reusable within the JCGE ecosystem.

Data import (IO/SAM)

JCGEImportData provides released source adapters for Eurostat FIGARO, national supply–use tables and national accounts, selected Eurostat satellite accounts, BEA Make/Use and national-accounts tables, and OECD ICIO archives. It normalizes selected source accounts into SUT, IO, satellite, and canonical data artefacts; it also provides balance diagnostics and a Model-D SUT-to-industry-by-industry IO transformation.

Downloads retain the declared source selection, raw responses, retrieval metadata, and SHA-256 checksums. The package deliberately does not infer a model's aggregation, account mapping, SAM closure, or behavioural assumptions: those remain explicit model-owned decisions.

Key outputs include normalized source tables, balance diagnostics, and the canonical files (sam.csv, sets.csv, and optional labels, subsets, mappings, and parameters) required by a model's calibration workflow.

  1. Select a published source release, accounts, valuation, and reference year.
  2. Retrieve or read the declared source tables and retain the source manifest.
  3. Normalize them to the relevant SUT, IO, national-account, or satellite form; apply Model D only when an industry-by-industry IO table is required.
  4. Diagnose source-table balances.
  5. Map accounts, aggregation, institutions, and closure explicitly in the model, then write sets.csv and sam.csv for calibration.

Use the Calibration guide once the canonical files are in place.

MPSGE import

JCGEImportMPSGE converts an MPSGE.jl model object to a JCGE RunSpec. This is a converter and conformance bridge, not a competing authoring format.

Typical flow:

using MPSGE, JCGEImportMPSGE
m = MPSGEModel()
# build MPSGE model...
run_spec = import_mpsge(m)

When the source model is complementarity-based, the importer emits MCP blocks so the model can be solved with PATHSolver.

Choosing an import path

  • Use JCGEImportData when you are starting from data and building new models.
  • Use JCGEImportMPSGE when you need to translate an existing MPSGE model.
