Global Trade Analysis Project (GTAP)

The Global Trade Analysis Project (GTAP) is a global network of researchers and policy makers conducting quantitative analysis of international policy issues. GTAP is coordinated by the Center for Global Trade Analysis in Purdue University's Department of Agricultural Economics.

I plan to use the GTAP course to learn about the fundamentals of CGE modeling and how it can be applied professionally. Additionally, I would like to learn about the dynamics of global trade and how it can be accurately modeled for scenario analysis. By the end of the course, I hope to be able to conduct simulations that examine global economic activity under different scenarios and economic assumptions.

I want to be familiar with the theoritical and practical aspect of GTAP and Computable General Equilibrium Model in applied economic policy analysis related to micro and macroeconomic issues.After the completion of the course, I would like to apply the practical knowledge to the modelling and policy analysis of Nepalese economy which is affected by various internal and external driving forces.

Luciana Porfirio
Postdoctoral Fellow

Governments write policy to address climate change adaptation, but this could have different impacts on society, the economy and the environment. Learning to use GTAP will assist me to test different policy options to achieve, for example, CO2 mitigation targets. I am a postdoctoral fellow at the CSIRO in Australia, working with the Australian Global Integrated Assessment Model.

Brad Gilmour
Agronomist, Agricultural Economist
Mouralea Trade, Resources and Agriculture Consulting

Brad Gilmour has extensive experience working as a trade, agriculture, resources and policy analyst. He has worked in both the private and public sector on both sides of the Pacific. With his collaborators, he has employed his analytical skills to challenges facing the agriculture and resource sectors in China, Japan, Korea, India and elsewhere in South, East and South-East Asia. Brad has also maintained an active interest in resource governance issues as well as the role that demographics play in the evolution of the agriculture and resource sectors. He is the author, co-author or editor of a number of monographs, articles and books relating to agriculture and resource governance, demographics, Pacific Rim agri-food sectors and international agricultural trade issues. Through participation in the GTAP initiative, Brad hopes to deepen his capacity to analyze the linkages between different sectors, policies and developments within agri-food value chains and resource sectors world-wide.

This course offers an excellent opportunity to gain skills on economic modeling. It fits well into my career goal as I am aiming to become specialized in economic model building - from static to dynamic. My current job in the Economic Modeling Unit of International Finance Corporation (IFC) gives me ample scopes to develop dynamic models in developing countries. My key take away will be to acquire the necessary skills for design and implementation of models and learn how they transform into economic policy choices.

Economist, Statistical Analyst, Performance Evaluations and Thematic Studies Division Chief
Banque Ouest Africaine de Développement (BOAD)

GTAP 101 course is the first step in my quest to foster my knowledge and my "know-how" in quantifying ex ante impacts of several development policies or programs using General Equilibrium Models. I wish to know, at beginner level, how to build and run an CGE model to conduct ex ante evaluations of tax policies and factor markets regulation. At the end of this course, I will use my knowledge to improve quality of my contributions during policy and program design stages in West African and Monetary Union (WAEMU). Besides, the outcome of this training will be very useful for future because I would like to have an intermediate level training in the coming years.

Coursework based on:
Introduction to Computable General Equilibrium Models
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.

Dates/Deadlines (EST)
Application Apr 5
Acceptance Notifications May
Online Course Aug 10-Sep 27
The course consists of a mix of daily lectures, lab assignments and informal discussions designed to introduce participants to the basic features of the Dynamic GTAP Model allowing participants to leave with the capability of conducting and analyzing their own GDyn simulations. The objectives of the course are:
  • To introduce participants to a dynamic model designed for conducting global trade analysis in an applied general equilibrium setting
  • To provide participants with ample hands-on training with software that has been tailored for undertaking analysis using a dynamic recursive model
  • To give participants the opportunity to interact with economists working on global trade and resource use issues using a dynamic modeling framework
