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

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.

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:

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).
