Title: Creating a GTAP Baseline for 2014 to 2050 With Special Reference to Canada

Authors: Peter B. Dixon and Maureen T. Rimmer


By 2020, the GTAP team had created 4 comparable GTAP databases, referring to the years 2004, 2007, 2011 and 2014. They had also produced a preliminary 2017 database. The aim of the project reported in this paper was to use this time series of databases to derive and apply methods for:

  1. estimating trends at a disaggregated level in industry technologies and consumer preferences;
  2. creating baseline forecasts incorporating a wide range of macro, demographic and energy forecasts from specialist organizations together with disaggregated technology and preference trends; and
  3. updating and checking GTAP databases, and establishing validation methods for assessing the performance of baseline forecasts.

Towards these objectives, we produced several interim reports and 3 final reports. This paper explains our methods and reviews the project findings.
