MIRAGE is a multisector, multiregion CGE model that operates in a sequential dynamic recursive set-up.

From the supply side in each sector, the production function is a Leontief function of value-added and intermediate inputs. The intermediate inputs function is a nested two-level constant elasticity of substitution (CES) function of all goods. This means that substitutability

The IMPACT model is a representation of a competitive world agricultural market. It is specified for 30 crop and livestock commodities, including cereals, soybeans, cotton, roots and tubers, meats, milk, eggs, oils, sugar/sweeteners, fruits/vegetables, and fish. It is specified as a set of 115 countries and regions within each of which supply, demand, and prices for agricultural

The Economy-Wide Multi-Market (EMM) model is based on neoclassical microeconomic theory. In the model, an aggregate producer represents a specific zone’s production of a specific sector. In this application for Ethiopia, there are a total of 2,352 (42 sub-sectors x 56 zones) such representative producers. Consistent with the setup of many other multi-market models, the

The standard computable general equilibrium (CGE) model is a static single country model documented in an IFPRI Technical Guide that discusses the implementation of the model in GAMS (General Algebraic Modeling System). The guide is accompanied by a CD-ROM that includes the GAMS input files for the model, sample databases, simulations, solution reports, and a social accounting

The standard GTAP Model is a multiregion, multisector, computable general equilibrium model with perfect competition and constant returns to scale. Innovative aspects of this model include: (i) the treatment of private household preferences using the non-homothetic CDE functional form and (ii) the explicit treatment of international trade and transport margins. Bilateral trade is handled

The PEP 1-t model is a recursive dynamic general equilibrium model. It follows the PEP 1-1 single-country, single-period model that emerged from a collaboration between Bernard Decaluwe, André Lemelin, Véronique Robichaud, and Hélène Maisonnave. The model is designed for the study of an archetypal national economy. It will enable researchers to develop a relatively standard model and apply

The PEP 1-1 model (1 period – 1 country) is a static general equilibrium model that emerged from a collaboration between Bernard Decaluwe, André Lemelin, Véronique Robichaud, and Hélène Maisonnave. The model is designed for the study of an archetypal national economy. It will enable researchers to develop a relatively standard model and apply it easily to their own country,

DREAM, or Dynamic Research EvaluAtion for Management, is a menu-driven software package for evaluating the economic impacts of agricultural research and development (R&D). Users can simulate a range of market, technology adoption, research spillover, and trade policy scenarios based on a flexible, multi-market, partial equilibrium model.

With DREAM you

The TASTE program has been designed to allow a large number of users to analyze existing trade policies and perform tariff scenarios. It is based on the MAcMap-HS6 database (version 2, baseyear 2004). It addresses several needs in terms of trade policy analysis. Among them:

Different from many single-commodity partial equilibrium models, the Export Restrictions And import Tariffs Overall impacts (ERATO) model illustrates how a multi-market model can be used to analyze trade policy options in a context of a multi-product value chain. It can also be used to study different productivity shock or tax changes in a sectoral value chain. The ERATO model is a member
