Choose a bundled model

CGE-Core 0.8.0 gives four model families a similar practitioner workflow while preserving their different economics and, where appropriate, different internal execution paths.

Model	Best used for	Important boundary
SimpleCGE	learning factor/commodity equilibrium	no government, trade, intermediates
StandardCGE	static sectoral tax, tariff, world-price and endowment experiments	representative household, static model
CamCGE	reproduction of the published Cameroon model and its experiments	historical replication, not a generic country template
IFPRICGE	richer institutions and explicit macro-closure scenarios	public synthetic data and official-source evidence remain separate

SimpleCGE

from cge_core import SimpleCGE
base = SimpleCGE.example().solve()

StandardCGE

from cge_core import StandardCGE
base = StandardCGE.example().solve()

The Hosoe Standard model includes intermediate inputs, factor demand, a representative household, government, production taxes, tariffs, Armington imports, CET exports, saving and investment.

CamCGE

from cge_core import CamCGE
base = CamCGE.example().solve()

CAMCGE keeps its own savings-driven closure (mps fixed, caeq redundant). It is not silently converted to the Hosoe closure simply to fit the same façade.

IFPRICGE

from cge_core import IFPRICGE
base = IFPRICGE.synthetic().solve()

Named scenarios include TARCUT1, TARCUT2, FSAVINCR, PWMINCR, and DEVAL. Their meaning depends on the IFPRI macro closure, so they are intentionally model-specific rather than generic policy toggles. IFPRICGE therefore uses IFPRI-specific equilibrium/scenario/result classes rather than the generic CGE → Equilibrium → Scenario → Result implementation.
