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?

Canonical internal data model and interfaces for JCGE.

Responsibilities

• Core types for sets, mappings, benchmark containers, and RunSpec (run specification)
• Block interfaces and validation hooks
• Standard RunSpec builder and section/template helpers
• No JuMP dependency

RunSpec builder (sections + templates)

JCGECore provides a lightweight builder to standardize RunSpec assembly:

• SectionSpec groups blocks by semantic section (e.g., :production, :trade).
• RunSpecTemplate declares required sections for a model family.
• build_spec assembles a RunSpec with required-section validation, optional allowed-section checks, and required-nonempty sections.

Non-goals

• Solving, model construction, or calibration implementations

Validation

Use validate_spec for optional structural checks on a RunSpec:

report = JCGECore.validate_spec(spec)
report.ok || println(report.categories)
