Course Content

The GTAP Short Course is an intensive training course in the economics of global policy analysis. The five-day, onsite course is supplemented with five online preparatory modules that introduce the data, core economic behaviors, and computational implementation of GTAP. Each module consists of approximately four hours of online content delivered as lectures and demonstrations, and includes tools for both self-evaluation and for feedback from the instruction team. The five-day residency course incorporates two phases. The first phase incorporates lectures, discussion, and hands-on lab sessions. The sequence of lectures and labs is designed to prepare students for their first GTAP-based analysis, the focus of the second phase of the residency. In that second phase, students are required to replicate and then extend, or adapt, the GTAP Model to address a policy question using the methods presented in the course. The successful participant will have gained fluency with the GTAP Model code and data base and be prepared to design economic policy experiments for computational analysis.

  • introduce participants to a standardized framework (GTAP Model, v7) for conducting global policy analysis in an applied general equilibrium setting
  • provide participants with hands-on training with software that has been tailored to instruction and collaboration in economic analysis with minimal software manipulation overhead
  • deliver participants an opportunity to interact with economists working on global trade and resource use issues and provide the perfect entry point to the international network of AGE modelers and policy analysts using GTAP data and models

The GTAP Short Course is comprised of an online instruction program followed by an intensive onsite course delivered by a team of GTAP specialists in data, model construction, and policy analysts. Note that the online and onsite portions of the course are not offered separately.

  • Part I: Online
    Content Overview
    • Prep Week - "Getting Started"
    • Week 1 – "Introduction to GTAP's Software Environment"
    • Week 2 – "Production and Supply in GTAP"
    • Week 3 – "Consumer Demand in GTAP"
    • Week 4 – "Multimarket Equilibrium in GTAP"
    • Week 5 – "Economic Policy Representation in GTAP"
    Time Commitment
    Participants should expect to spend approximately 4 hours/week during the online portion of the course.
  • Part II: Onsite - The onsite portion of the GTAP Short Course focuses on applied policy analysis, aimed at helping students master the techniques for developing policy scenarios and understanding the economic interactions that 'drive' CGE model impacts. A core learning objective of the onsite course is preparing students to contribute to policy debates using quantitative analyses developed from the standard GTAP framework and the suite of model 'extensions' that have been developed for more specialized analysis. The GTAP Short Course ends with a capstone experience where students complete their own detailed trade or resource policy analysis making use of published application materials and extensions to the GTAP model data and code. Depending on enrollment and the participant pool, capstone applications for the course will be drawn from the list below. We strongly encourage prospective participants to indicate which capstone applications are of primary interest in their application.
    Lecture Content
    • Behavioral equations: Production, consumption, savings, trade and transport
    • Database: structure and composition, primary sources of data and the fitting process
    • Market equilibrium analysis: price and quantity linkages in a multi-market global model
    Laboratory Content
    • Interpreting model results of trade and technical change shocks
    • Changing the equilibrium rules: Unemployment, fixed trade balance, etc.
    • Quantitative analysis of welfare outcomes
    Capstone Project: Model Extensions for Replication and Extension

What GTAP Short Course "Graduates" Are Saying...
"Excellent learning environment, teaching and material.""

"Good balance between theory and practical lessons!"

"I thoroughly enjoyed the course and learned an incredible amount of material in such a short period of time. I look forward to being involved in the GTAP community in the future and using these modelling techniques in my work! Thank you!"

"I really loved the hands-on part of the course; it was a valuable experience and certainly provided a deeper understanding of the difficult and sophisticated linkages of the model."

"The course is very comprehensive and offered an opportunity to be introduced to all aspects of CGE modelling (theory, data, GEMPACK and other)."

All participants are expected to have a strong foundation in micro-economics. This should be at the level of a calculus-based graduate course in micro-economic theory. Since the course software is designed around a PC environment, it is essential that each participant have access to such a machine. No prior programming or modeling experience is required. Due to the web-based nature of the course, participants will need access to a high-speed internet connection. The online assignments and course project will be implemented in the context of the RunGTAP software interface for GEMPACK. This is a Windows environment for conducting applied general equilibrium analysis. RunGTAP is designed to allow users to focus on economics with the programming details being largely taken care of behind the scenes where it runs GEMPACK programs. GEMPACK is an algebraic modeling language which permits the user to write out the model in a transparent fashion. It is specifically designed for application to large-scale, applied general equilibrium models in a policy-oriented environment.

ApplicationFebruary 28th Deadline

Individuals interested in taking this course must apply on the GTAP website. All applications will be reviewed following the deadline. Those accepted into the course will receive an email detailing how to register and arrange for payment. Note that application does not guarantee acceptance.


The registration fee for this course is $4,000 USD. This fee includes five days of onsite, individualized instruction in the form of lectures and labs as well as distance-learning prior to the onsite course. The course registration fee also includes daily coffee breaks, five lunches, one reception, and one dinner. Participants will be responsible for all other meals.

A limited number of fellowships may be available to students working on, or who are interested in, learning and applying CGE modeling to inform policy debates regarding the most pressing questions related to global economic analysis. The fellowships will cover $2,500 towards the registration fees, reducing the amount owed by the recipient to $1,500. Those interested in being considered for a fellowship should submit a two-page narrative (maximum, as a PDF) on the application form that describes their area of interest, accomplishments, and current/future research directions. To the extent possible, identify why the application of an economy-wide analytical framework will enhance the impact of your research as well as beneficiaries of your research. Please address how your previous training and professional/academic experience have prepared you for formal policy analysis. The name and contact information for two references, professional or academic, should also be included at the end of the document. Demand for this course, as well as fellowships, are very high; therefore, we encourage early application.
