GTAP Research: CGE Baseline Data and Documentation

At the 2010 GTAP Advisory Board Meeting and later at a workshop on baselines organized by the USITC and the Centre of Policy Studies in Shanghai, there was considerable interest in establishing a website where people could share baseline data and information on baseline data sources, as well as programs for updating GTAP data, filling and aggregating baseline data. 'Where do I find baseline data?' is also fast becoming the most frequently asked question amongst new GDyn users and other GTAP Network members.

Thomas Chappuis joined the Center for Global Trade Analysis to assist with the development of a new baseline for the Dynamic GTAP Model and to set up this baseline page where GTAP users can easily find and contribute data sources, baseline documentation and programs. Our view is that sharing data and expertise with researchers working on baselines will help create reliable and defendable baseline scenarios.

Projections for World CGE Model Baselines
by Chappuis, Thomas and Terrie Walmsley
Submitted: 9/19/2011

While constructing a new baseline for the GDyn model, we spent a lot of time collecting projections and deciding which data to choose. We also developed programs to aggregate projections to any specific geographical aggregation of the GTAP Data Base. In order to help researchers in the construction of their own baselines, we created a baseline section1 on the GTAP website where GTAP users can find the projections data and programs. The purpose of this paper is to document the data used in our new GDyn baseline and to provide a user guide of the baseline website. Our view is that sharing data and expertise with researchers working on baselines will help create reliable and defendable baseline scenarios. The second annex documents the aggregation programs from the 112 GTAP 7.1 regions to a specific geographical aggregation.

A Base Case Scenario for the Dynamic GTAP Model
by Walmsley, Terrie, Betina Dimaranan and Robert McDougall
Submitted: 10/27/2000

Paper developed for the Short Course on the Dynamic Model, October, 2000. The increasing interest in dynamic models and in particular the development of the Dynamic GTAP model at the Center for Global Trade Analysis has highlighted the need to develop a base case scenario depicting how the world economy might be expected the change over the next 20 years. The purpose of this paper is to show how such a base case scenario has been created for use with the Dynamic GTAP model (Ianchovichina, 1998 and Ianchovichina, McDougall and Hertel, 1999) and GTAP data base. This document is intended to be used in conjunction with a base case aggregation program which was constructed at the Center for Global Trade Analysis. This program takes as its inputs macro and policy forecasts and allows the user to: 1) alter various assumptions about the implementation of policies; and 2) aggregate over time, regions and commodities; to obtain a base case scenario which is specific to their needs. Although the base case program is specifically designed with the Dynamic GTAP model in mind, it is general enough to be used with other models. It should be noted however, that the base case scenario developed here is very general, it looks only at the standard macro aggregates and does not provide alternative optimistic or pessimistic scenarios.
