Course Content
Course Overview

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 and has two aims. The first is to give students practical experience using the software environment for solving GTAP models. The second is to review economic components of the model in a partial setting (e.g. production behavior or market equilibrium but no international trade). Phase one is completed immediately prior to the intensive, onsite portion of the course. Onsite training covers two phases and is taught over a five-day period. The first half of the onsite period (phase two) builds directly from prior training 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 in phase three. During this phase, course members working in small groups with a GTAP researcher will replicate prior work done with the GTAP model and data base and then develop their own question as an extension of that published study. It is in this third, capstone phase of the course where students gain the experience in scenario design, model tools, and analysis techniques that will prepare them to become contributors to global analysis in the GTAP network of researchers.

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 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. Participants should refer to the course website for a precise plan of study.

  • Phase I: Online Course
    Participants should expect to spend approximately 4 hours/week during the online portion of the course.
    • Prep Week – "Getting Started"
      • Students complete installation of course software packages and validate their installation with test experiments for the online instruction team
      • If the machine students use for online course is different than the computer they will bring to the onsite course, students must validate installation on that machine as well prior to departure
    • Module 1 - "Introduction to GTAP's Software Environment"
      • Topics Covered:
        • The RunGTAP Interface
        • Understanding Model Implementation in the TABLO Language
        • The GTAP Data Base
        • Simulation in GTAP

        • Demand data
        • Demand application
      • Module Objectives – Students move from the production to end-user side of the model in this module. Successful completion of the module will give students experience with:
        • treatments of final demand in general equilibrium and the specific assumptions made in GTAP
        • the GTAP "Regional Household" and the empirical form of public and private demands
        • the data flows and parametric assumptions that drive demand behavior in GTAP
        • examining simulation outputs including percentage change variables and updated data
    • Module 4 – "Prices and Policy Instruments"
      • Topics Covered:
        • GTAP policy wedges
        • The GTAP price system
        • Policy data, evaluating flows at different 'prices'
        • Multiple policy shocks application
      • Module Objectives – In this module, we connect the demand and supply sides of regional economies by examining the price system in GTAP. After finishing this module students will:
        • 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
    • Module 5 – "Single-Region Equilibrium"
      • Topics Covered:
        • Primary factor supply in GTAP
        • Market clearing conditions
        • GTAP Input-Output Tables and Walras' Law
        • Regional income and welfare
      • Module Objectives – We close our online study by considering the equilibrium conditions pertinent to the single-region setting. The module training will equip students for:
        • understanding the supply assumptions on land, labor and capital in GTAP
        • analyzing market clearing relationships in GTAP
        • reading the regional data structure in an IO context
        • identifying the welfare (money metric) consequences of policy shocks
    • Online Wrap-up
      • During the final, wrap-up week of the online phase of the course, participants will have a chance to catch up on any incomplete coursework and pose any final questions pertaining to the online material before departing for the onsite phase of the course.
  • Phases 2-3: Onsite Course
    Participants should expect to spend approximately 8-9 classroom hours/day during the onsite portion of the course.
    • Phase 2: "Multi-region Equilibrium and Global Economy Modeling"
      • First 2.5 days onsite
      • Students in phase two will be trained by the GTAP instruction team comprised of researchers from the Center for Global Trade Analysis and broader GTAP Network. The schedule of topics with their assignments in any course year will be provided to students the week prior to onsite instruction.
    • Phase 3: "Experiential Training, Student Investigations on Global Economy Issues"
      • Second 2.5 days onsite
      • Students in phase three will work in small groups with specialists in select research areas such as:
        • Commodity trade and regional free trade agreements
        • International farm and food policy measures
        • Energy policy and international policy measures
        • Environmental and land use policy assessments in a global setting
        • Migration and labor

    The planned topics for student extensions are advertised based on the instruction team and current research trends and developments. The final offerings for phase three topics are ultimately formed by reviewing student capabilities and requests.

    The curriculum and instruction team work to ensure that the core learning objectives and experience remain identical regardless of which 'extension' replication a student completes. The replication exercise is not a jump-start on a specific research agenda – it is a capstone of the phase one and two training that culminates in a final deliverable presentation to the course cohort and instruction team. Students are provided access to all replication and extension materials after the course ends. It is anticipated these materials will be key resources for students in continuing the type of self-directed study necessary to continue to hone skills and advance research skills with GTAP.

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.
