What is a CGE?

A Computable General Equilibrium (CGE) model is a quantitative economic model that represents an economy as interconnected markets for goods and services, factors of production, institutions, and the rest of the world. It is calibrated with data (typically a Social Accounting Matrix) and solved numerically as a system of nonlinear equations until equilibrium conditions (zero-profit, market-clearing, and income-balance) hold within tolerance.

What is JCGE?

JCGE is a block-based CGE modeling and execution framework in Julia. It defines a shared RunSpec structure and reusable blocks so models can be assembled, validated, solved, and compared consistently across packages.

What is this package?

Calibration utilities for common CGE functional forms.

Responsibilities

• Calibration helpers for CES/CET/Leontief/LES/Cobb–Douglas (as needed)
• Benchmark replication checks and share/scale parameter reconstruction
• No JuMP dependency

Canonical CSV schema (v0.1)

JCGECalibrate expects a single canonical CSV schema for model inputs. This schema is model-agnostic and can be generated by JCGEImportData.

Required files:

• sets.csv — columns: set, item
• sam.csv — SAM matrix with a label column for row labels and the remaining columns as SAM accounts

Optional files:

• subsets.csv — columns: subset, parent_set, item
• labels.csv — columns: set, item, label (optional description)
• mappings.csv — columns: map, from_item, to_item
• params.csv — columns: name, set1, index1, set2, index2, set3, index3, value, section

Notes:

• Scalar parameters use empty index columns.
• Section names should align with RunSpec sections (production, households, markets, etc.).
• sam.csv uses the explicit label column (older Column1 or empty headers are tolerated by the loader for now).

Inputs observed in current example models

These parameter names appear in packages/JCGEExamples/models/*/data/ and should map into params.csv as name entries:

• SAM-based models: sam.csv (plus sets from SAM labels)
• Cameroon models: io, imat, wdist, xle, m0, e0, xd0, k0, id0, dst0, depr, rhoc, rhot, eta, pd0, tm0, itax, cles, gles, kio, dstr, wa0, te, and scalars (er, gr0, gdtot0, cdtot0, fsav0, mps0)
• Korea models: io, imat, wdist, alphl, labres1, labres2, sectres, hhres, htax, cles, zz, and scalars (er, pindex, gdtot, deprecia, savings, invest, fsav, fbor, remit, tothhtax, y)

Non-goals

• Model building or equation definitions
