Independent CGE modelling

When a model needs to hold up to scrutiny.

Most CGE results can't be interrogated. Griffin CGE Solutions builds models where every assumption, transmission channel, and number is traceable — providing CGE modelling, Social Accounting Matrix construction, GAMS training, model review, and policy impact analysis for governments, international institutions, and advisory teams.

Why Griffin CGE

Transparent modelling for decisions that require confidence.

Good CGE modelling should do more than produce headline GDP numbers. It should show how a shock or reform moves through sectors, households, prices, trade, fiscal balances, and macroeconomic aggregates.

Transparency

Transparent by design

Models are built from official international and national data sources, with documented assumptions, clear closure rules, and auditable workflows.

Policy use

Policy-relevant outputs

Results are structured around the policy question: who is affected, through which channels, and under which assumptions.

Capacity

Client-owned capability

Training, model documentation, and source-code access help clients understand, adapt, and reuse the analytical framework.

Featured policy insight

Stress-testing economies under trade, energy, and fiscal shocks.

Standard macro forecasts often show the headline outcome. CGE modelling shows the anatomy of the shock: which sectors absorb the damage, how prices and incomes adjust, how trade flows change, and how public finances respond.

Applications include energy-market disruption, trade-route shocks, import-price transmission, fiscal reform, household welfare, emissions policy, and structural transformation.

From aggregate effects to transmission channels

Model outputs can be structured for ministries, multilateral teams, advisory firms, and non-technical stakeholders.

  • Macroeconomic outcomes: GDP, consumption, investment, trade, public finances.
  • Sectoral outcomes: production, prices, employment, imports, exports.
  • Distributional outcomes: household welfare, income groups, poverty-related indicators where data permit.
  • Scenario comparison: baseline, policy reform, external shock, and sensitivity cases.

Training

Practical GAMS and CGE training for policy analysts.

Griffin CGE Solutions is listed by GAMS as an established training partner. Courses are built around three parallel tracks that advance together: economic theory, SAM data construction, and GAMS implementation — so participants understand not just how to run a model, but why it produces the results it does.

The core programme runs across five modules and can be delivered intensively over five days or spread across sessions. An advanced sixth module covers multi-regional CGE frameworks. In-house and bespoke versions are available, with content tailored to a specific sector focus (energy and climate, agriculture, trade, public finance) or a particular country dataset.

Typical audiences include ministries of finance, economy, planning, trade, energy, and climate; central banks; statistical offices; universities; international organisations; and consulting teams.

Course modules can include

  • Introduction to CGE concepts and policy uses.
  • SAM construction and reconciliation.
  • GAMS syntax, calibration, and model solving.
  • Closure rules, scenario design, and sensitivity analysis.
  • Interpreting results for non-technical policy audiences.
Recognition

World Bank Group recognition for collaborative policy analysis.

Peter Griffin has received World Bank Group team awards in connection with three assignments: the Gaza Rapid Damage and Needs Assessment (World Bank / EU / UN, 2021), the Beirut Rapid Damage and Needs Assessment (World Bank / EU / UN, 2020), and the Palestine Prospects for Growth and Jobs general equilibrium analysis (World Bank, 2017). These awards reflect the quality and policy relevance of collaborative economy-wide modelling work conducted for governments and multilateral institutions.

About

About Griffin CGE Solutions

Applied economic modelling should be transparent enough to scrutinise, practical enough to use, and clear enough to inform decisions.

Griffin CGE Solutions is a specialist economic-modelling practice focused on computable general equilibrium modelling, macro-consistent modelling, Social Accounting Matrices, GAMS training, and policy impact analysis.

The firm was founded by Peter Griffin, an economist with 35+ years of applied modelling experience across 60+ countries. His published work includes co-authorship on World Bank policy research on Egypt's energy subsidies, the Jordan COVID-19 CGE and microsimulation analysis, and a recursive-dynamic general equilibrium model of Poland. He has contributed macroeconomic impact analysis to the Gaza and Beirut Rapid Damage and Needs Assessments, and has delivered country models and advisory assignments for institutions including the World Bank, IMF, ADB, EU, USAID, and national ministries of finance.

Griffin CGE Solutions serves clients who need specialist modelling expertise without black-box methods: transparent assumptions, documented data, auditable workflows, and results structured for policy use.
