Course Content

Course Objectives and Expectations
The successful participant will demonstrate fluency with the GTAP Model code and data base by designing an economic policy experiment and communicating analysis to the course cohort and teaching team. The learning objectives fostered by the distribution of course activities reflect the ultimate goal and include:

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

Course Structure
The GTAP Short Course is an intensive training course in the economics of global policy analysis delivered by a team of GTAP specialists in data, model construction, and policy analysts.

  • Phase 1: Asynchronous Online Learning
    Phase 1 consists of asynchronous online learning, during which participants should expect to spend approximately 4 hours/week on the course. Phase 1 aims to give students practical experience using the software environment for solving GTAP models while reviewing economic components of the model in a partial setting (e.g., production behavior or market equilibrium, but no international trade). Students will also learn the construction of, and analysis with, a global economy model with bilateral trade and relevant policy instruments.
    • Module 0 - "Prep Week"
      • Course software installation and setup
    • Module 1 - "Introduction to GTAP's Software Environment"

        • know the major policy instruments on transaction in GTAP
        • understand how policy shocks transmit to the price system
        • be able to identify the data components that define base equilibrium policy levels
        • examine simulation outputs from multiple interacting policy instruments
      • Topics Covered:
        • Theory of Prices
        • Price Linkage Equations in GTAP
        • Price Linkage Data
        • Simulation Exercise – Multiple Tax Adjustments
    • Module 5 - "Balance and Equilibrium Conditions in GTAP"
      • Module Objectives - In this module, we consider the equilibrium conditions pertinent to the single-region setting. The module training will introduce students to:
        • the accounting theory underlying GTAP
        • navigation of market clearing equations in GTAP v7
        • the accounting basis of the GTAP data matrix
        • simulation concepts for linearized economic models
      • Topics Covered:
        • Theory of Markets
        • Equilibrium Conditions in the GTAP
        • Market Clearing Data - Numerical Example for SSA Food
        • Simulation Application – Revisiting Linearization
    • Module 6 - "Introducing the GTAP Open Economy"
      • Module Objectives - In this module, we expand our view of the GTAP Model to the open economy setting by returning to the equilibrium conditions previously studied in a single region setting and exploring the additions required to model trade linkages between regions. In this module students will gain knowledge of the:
        • GTAP multi-region economy and its key linkages
        • fundamental accounting relationships of the multi-region economy in GTAP
        • expanded price system required for the multi-region setting
        • export supply and import demand basics for GTAP’s international trade treatment
      • Topics Covered:
        • Overview of the GTAP Framework
        • Accounting Relationships and Market Clearing Conditions
        • Price Linkages and Taxes in the Multi-region Model
        • Behavioral Equations for Production
        • Trade, Armington, and Transportation
        • Interpreting Model Results (Tariff Impacts)
    • Phase 1 - "Wrap-up Week"
      • During the final week of phase 1, participants will have a chance to catch up on any incomplete coursework and pose any remaining questions pertaining to the material covered before moving onto phase 2.
  • Phase 2: Onsite Residency
    Phase 2 consists of live, onsite instruction of approximately 8-9 hours/day focusing 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 this phase 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. Phase 2 culminates 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. A key learning objective of phase 2 is developing capacity for linking the core GTAP model to new data products or modeling sub-systems. We demonstrate this with new applications in climate and energy policy (tracking global emissions from land use change) and trade liberalization (tracking nutrition outcomes of tariff removal).

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.
