The GTAP Short Course is an intensive training course in the economics of global policy analysis.

  • 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

GTAP Working Paper

Incorporating Nutritional Accounts in the GTAP Data Base

by Chepeliev, Maksym

In this paper, we develop an approach towards incorporation of nutritional accounts for the Global Trade Analysis Project (GTAP) Data Base. We rely on the Food and Agricultural Organization (FAO) food balance sheets data and nutritive indicators to estimate nutritional content of primary commodities and derived commodities represented in primary equivalent within the food balance sheets. Calories, fats, proteins and carbohydrates are estimated and reported. We further identify use categories that account for food, feed, seed, losses and other uses. In terms of food supply, we identify GTAP Data Base primary commodity sectors, food processing sectors and service sectors that supply food. To redistribute nutritional data according to GTAP Data Base sectors, we calculate Leontief inverses, operating only over those sectors (and uses) that supply food. Trade in both primary and processed commodities is taken into account. The approach is applied to all four GTAP 10 Data Base reference years and can be replicated in a dynamic modelling framework for each simulated year (time step).

Dates/Deadlines (USA Eastern Time Zone)
Course Application September 27 – January 2
Acceptance Notifications early February

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.
