GTAP Research Memorandum

Development of GTAP version 10 Land Use and Land Cover Data Base for years 2004, 2007, 2011 and 2014

by Baldos, Uris Lantz and Erwin Corong

Understanding the challenges of achieving environmental sustainability goals given future demand for food, fiber and fuel requires economic frameworks that incorporate spatially explicit information on land use and land cover (LULC). The GTAP LULC Data Base and its variants have been extensively used in a wide variety of applications aimed at examining the land-environment-energy nexus (Golub et al., 2012; Hertel et al., 2010; Johnson et al., 2019; Liu et al., 2014; Peña-Lévano et al., 2019; Stevenson et al., 2013; Taheripour et al., 2010; Taheripour & Tyner, 2012).

28th Annual Short Course in Global Trade Analysis
"Theory and Applications of Computable General Equilibrium Analysis with the GTAP Model"
July 26-30, 2021   |   West Lafayette, Indiana, USA

Purdue University
Purdue University
Dates/Deadlines (USA Eastern Time Zone)
Applications Nov 9 – Feb 28
Acceptance Notifications April
Online Course May 10 - July 11

The GTAP Short Course is an intensive training course in the economics of global policy analysis. The course is delivered in three phases. Phase one is entirely delivered online, designed to give students practical experience using the software environment for solving GTAP models and to review economic components of the model in a partial setting. Phase two is the onsite training, building from the onsite period and is comprised of lectures, labs, and discussion on the construction of and analysis with a global economy model with bilateral trade and relevant policy instruments. Finally, students are given the opportunity to prepare their own global economy investigation and gain the experience in scenario design, model tools, and analysis techniques.

Coursework based on:
Introduction to Computable General Equilibrium Models
by Mary E. Burfisher

The GTAP PTA Course is designed to provide professionals and students with hands-on, applied training in the analysis of preferential trade agreements (PTAs) using the GTAP computable general equilibrium model. The objectives of the GTAP PTA course are to provide participants with an opportunity to develop their applied skills in the design of PTA experiments, the implementation of changes in tariff and non-tariff barriers, and the analysis of model results.
2021-1 GTAP 101 Course
"Introduction to Computable General Equilibrium Modeling"
March 15 – May 2, 2021

Coursework based on:
Introduction to Computable General Equilibrium Models, 2e
by Mary E. Burfisher

The objective of GTAP 101 is to engage participants in an active, team-based process of learning about the GTAP CGE model and its use in applied economic policy analysis. The curriculum is geared to advanced undergraduates, graduates and professionals. Following the course, participants will be entry-level modelers and more informed consumers of CGE-based analyses.
