Family: multi-market partial equilibrium model
Spatial Extent: global

This is a partial equilibrium model for trade policy analysis (PE-TRADE) which is set up in Excel. The PE-TRADE model in Excel shows multiple examples of trade policy analyses with increasing details in each worksheet. In these examples, the focus is on the response of import demand to changes in trade policy and other tax policy instruments.

This module on gravity equations is composed of a literature review summarizing the key points and references you have to know when interested to estimate a gravity equation and a set of illustrative STATA program used to perform such estimations.

Family: multi-market partial equilibrium model
Spatial Extent: global

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 of the MUlti Sectoral partial Equilibrium models (MUSE) developed for the AGRODEP Consortium.

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:

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.

Family: single-country computable general equilibrium model
Spatial Extent: national

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, whatever the particular structure of their social accounting matrix (SAM).

Family: single-country computable general equilibrium model
Spatial Extent: national

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 it easily to their own country, whatever the particular structure of their Social Accounting Matrix (SAM).

Family: multi-country computable general equilibrium model
Spatial Extent: global

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 via the Armington assumption. A global banking sector intermediates between global savings and consumption.

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