G-Cubed G-Cubed model versions
Table of contents
The G-Cubed model versions currently documented are summarised below.
Two Sector / Two Region Models
The 2 sectors differentiate between an energy sector (electricity and fossil fuels) and a second sector that aggregates all other sectors.
Model 2R is the symmetric teaching model of the USA and the Rest of the World. The Rest of the World data and parameters are adjusted to match the USA, making it useful for demonstrations and experiments where regional asymmetry is not the focus.
Six Sector Models
The 6 sector models aggregate production into energy, mining, agriculture, durable manufacturing, non-durable manufacturing, and services. They provide lighter-weight model versions for experiments where the full 12 or 22 sector structure is not required.
Model 6M focuses on providing more regional detail for Asia.
Model 6N is developed for users with a specific interest in the New Zealand economy. It was forked from 6M and splits the advanced economies region into New Zealand and Canada.
Model 6W extends the 6M regional structure by adding Pakistan, Bangladesh, and Sri Lanka as explicit regions.
Model 6T uses the 6 sector structure with Taiwan separated as an explicit region.
Model 6G provides a broader major-economy regional structure, including more detail within Europe and several G20 economies.
Seven Sector Models
The 7 sector models extend the 6 sector structure by splitting one sector into a more detailed sector that is useful for targeted experiments.
Model 7N is split from 6N to include a high-tech manufacturing sector.
Model 7W is forked from 6W and splits health services from other services.
Twelve Sector Models
The 12 sector models add transportation and construction sectors, and split the single energy sector in the 6 sector models into electricity distribution, gas extraction and utilities, petroleum refining, coal mining, and crude oil extraction.
Model 12N extends 6N to have 12 sectors while retaining the New Zealand-focused regional structure.
Model 12T uses the 12 sector structure with Taiwan separated as an explicit region.
Model 12U uses a compact 12-region aggregation with the United Kingdom, Vietnam, and oil-exporting economies represented explicitly.
Model 12W combines the regions of 6W with the 12 GTAP sectors used in the larger sectoral models, without the electricity generation sectors.
Twenty-two Sector Models
The 22 sector models track all greenhouse gas emissions (CO2, Methane, Nitrogen Dioxide, and CFCs). To do so, they split the agriculture sector into 3 sectors: crops, livestock, and other agriculture. The emission intensity parameters are calibrated using GTAP data.
Model 22U has 12 regions and 22 sectors. It adds crops and livestock sectors and includes all greenhouse gases.
Model 22W uses the regions of 6W and the sectors of 22U, combining the wider Asian regional detail with the greenhouse-gas sector structure.
