This model allows members to explore the sensitivity of computable general equilibrium (CGE) models to the choice of macroeconomic closure rules using the case of the standard IFPRI model for Nigeria and Tanzania. Two sets of simulations are performed: a 50 percent decrease in import taxes and a 10 percent increase in agricultural productivity. For each simulated scenario, we study around 10 closure rules related to the government, the rest of the world, the investment-savings equilibrium, and the factors market.

The spatial equilibrium model is a multi-region partial equilibrium model which links producers and consumers from different locations. It allows economists to examine the global economic and trade consequences of diverse trade policies by determining their effects on market, trade and welfare variables. As an example, it evaluates the impact of such policies on supply and demand, producer and consumer prices, volume and direction of trade, consumer and producer surpluses, as well as on world welfare.

The AGRODEP GAMS Training Toolbox is intended to assist those interested in economic modeling-- including but not limited to general and partial equilibrium models as well as optimization problems-- by teaching them to use the GAMS software, a cornerstone of many modeling efforts. These economic models can be used to conduct research on a wide range of topics, such as analysis of various forms of policies, issues pertaining to agricultural growth and poverty, climate change, natural resource management, and the role of science and technology.

La Boîte à Outils "Formation GAMS AGRODEP" vise à aider ceux qui s'intéressent à la modélisation économique, incluant (sans s'y limiter) les modèles d'équilibre général et partiel ainsi que les problèmes d'optimisation, en leur apprenant à se servir du logiciel GAMS, un instrument essentiel dans les pratiques contemporaines de modélisation.

PETS is a multi-region, multi-sector, dynamically recursive, and partial equilibrium (PE) model. The model developed in Fontagne, Laborde, and Mitaritonna (2011) focuses on trade policy analysis using disaggregated geographical and sectoral levels of data. The model emphasizes the demand side, which is specified as a nested CES structure, where the initial regional income is assumed to be fixed. The demand is expressed at various levels of disaggregation matched by increasing substitutability (elasticity of substitution increases with higher level of disaggregation).

The approach of this macroeconometric modelling method is unique in two ways: First, it will be extremely developed, with the goal of giving modelers a complete set of elements which will allow them to build their own models. To this end, our presentation is complemented by examples using the EViews software, from general strategies to technical details. The associated programs and files are provided. Second, it will focus on Africa, to which all our examples will relate.

The Supply and Demand Elasticities Toolbox provides a technical guide, Stata code, and data files to estimate supply and demand elasticities. The first portion of the guide is dedicated to the estimation of elasticities in producer theory and portion two is dedicated to elasticities in consumer theory. This toolbox is restricted to AGRODEP members and AGRODEP affiliate members only.

MIRAGRODEP is a dynamic multi-country, multi-sector general equilibrium model. The dynamics is recursive and the model is calibrated on the GTAP database. MIRAGRODEP is a new version of the MIRAGE model of the world economy, whose GAMS code has been simplified and presented in a more compact and user-friendly way.

This toolbox contains the codes used to run microsimulations linked to CGE models. As a specific example, it uses the IFPRI standard CGE model and the Tanzania Household Budget Survey 2000/2001 to simulate a 50% fall in export prices in Tanzania. Two microsimulation techniques are implemented: a non-parametric microsimulation model and a representative household model.
Three main source codes are presented:
