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). Like the static model (PEP 1-1), the PEP1-t model distinguishes several categories of factors (labor and capital). It also takes into account all possible transfers between agents and a large set of tax instruments. Furthermore, the aggregate output of each industry consists of several products, consistent with non-square input-output tables. The authors have also written the GAMS code in a general form in order to facilitate the application of the model to a broader set of aggregated SAMs.
The GAMS codes of PEP 1-t model are available to AGRODEP members.
The following additional resources are available to AGRODEP members:
- PDF file (PEP 1-t.pdf) provides a full description of the models.
- User guide (PEP 1-t User Guide.pdf) presents a brief description of the model and explains in detail how to implement it in GAMS.
A new version (2.1) of the model is now available on the PEP website. The principal changes include a reformulation of the GDP deflator, an introduction of new real (volume) variables, an external excel file which contains the exogenous parameters and a new calibration procedure of the quantity demanded of the composite commodity.
