GTAP Course 3x3 aggregation SSAEURW
Originally developed for the African Short Course in Global Trade Analysis January 25-31, 1998.
See also the African Short Course version of the "Hands-on Document to Introduce GEMPACK, GTAP and RunGTAP" in GTAP's web site for more information about these experiments and how to use them to learn about RunGTAP and GEMPACK.

I.   SUMMARY
This small version of GTAP uses a 3-good, 3-region aggregation. Four closures are provided, corresponding to different combinations of single/multi regional, general/partial equilibrium exogenous settings. The PE closures are with respect to non-food products (food price and output remain endogenous). The SR closures are with respect to the EU and ROW (income, prices and acitivity levels in the SSA remain fully endogenous).

II.   REGIONS AND COMMODITIES


The regions are:
SSA	Sub-Sahara Africa, inclusive of South Africa
EU	European Union
ROW	Rest of the World

The 3 goods are:
food	food and agriculture
mnfcs	resources and manufactures
svces	all services

which are aggregated as follows:

food:
Paddy rice, Wheat, Cereal grains nec, Vegetables, fruit, nuts, Oil seeds, Sugar cane, sugar beet, Plant-based fibers, Crops nec, Bovine cattle, sheep and goats, horses, Animal products, Raw milk Wool silk-worm cocoons, Bovine cattle, sheep and goat, horse meat prods, Meat products nec, Vegetable oils and fats, Dairy products, Processed rice, Sugar, Food products nec, Beverages and tobacco products

resources and manufactures:
Forestry, Fishing, Coal, Oil, Gas, Minerals nec, Textiles, Wearing apparel, Leather products, Wood products, Paper products, publishing, Petroleum, coal products, Chemical, rubber, plastic products, Mineral products nec, Ferrous metals, Metals nec, Metal products, Motor vehicles and parts, Transport equipment nec, Electronic equipment, Machinery and equipment nec, Manufactures nec

services:
Electricity, Gas manufacture, distribution, Water, Construction Trade, transport, Financial, business, recreational services, Public admin and defence, education, health, Dwellings & Svces 

III.   EXPERIMENT FILES: SHOCKS, CLOSURES AND SOLUTION METHOD- :

SHOCKS
The basic experiments in this version include:
- numeraire shock
- selected experiments from the Hands-on document
- elimination of the import tariff on SSA food imported by the EU
- elimination of all tariffs and export taxes/subsidies levied by the EU on 
trade with SSA
 

CLOSURES
Four different closures are explored here in the context of the fourth set of shocks above:
Standard Multiregional GE closure
Multi-regional partial equilibrium closure for food
Single region Sub-Saharan Africa, general equilibrium closure
Single region Sub-Saharan Africa, partial equilibrium closure for food

SOLUTION METHODS
Several experiments use the Johansen solution method -- for instructional purposes.
However, the preferred solution method for policy analysis is Gragg 2-4-6 -- with automatic
accuracy if large shocks are undertaken.
