IFPRI public path and clean-room boundary

IFPRI public path and clean-room boundary#

CGE-Core keeps two IFPRI evidence lanes deliberately separate.

1. Redistributable public lane#

The package includes an independently authored synthetic IFPRI-format economy. It is used for:

  • public CI;

  • wheel/package smoke tests;

  • Colab and tutorials;

  • exercising calibration, closure, policy-scenario, reporting, and solver paths;

  • verifying that the IFPRI implementation can run without restricted external inputs.

from cge_core import IFPRICGE

base = IFPRICGE.synthetic().solve()
result = base.scenario("TARCUT1").solve()

This dataset is not the official IFPRI benchmark.

2. Official-source replication lane#

The official benchmark comparison requires separately obtained source material. CGE-Core does not redistribute that source package or test.dat.

Users who possess the required source material can use the advanced cge_core.models.ifpri official-source path. External-data tests remain marked separately from public synthetic tests.

What may be claimed#

A successful synthetic run demonstrates that the public software path works on the redistributable synthetic economy. It does not by itself prove equality with the official IFPRI benchmark.

The official replication claim rests on the separately executed official-source comparison and its retained validation targets. Documentation and tests should never collapse those two statements into one.
