No. 01 - A comparison between the PEP 1-1 model and the IFPRI standard model

The purpose of this document is to give a brief comparison between two models widely used by economists for policy analysis: the PEP 1-1 model and the IFPRI standard model. We present their main similarities and differences, particularly from a theoretical point of view. It is not a full description of these models. We highly recommend the reader to read the manuals and user guides which come with the models in order to have a complete overview. We neither discuss in detail the presentation strategy adopted in the manuals (such as the mathematical derivation of the equations) nor the different files that constitute the models. The reader is also encouraged to visit the websites of the two institutions (IFPRI and PEP) wherein he may find some training materials about the models and a series of studies which use them.
