This paper documents the PEP-w-1 model developed by four members of the PEP research network. The PEP-w-1 model extends the PEP-1-1 single-country, single-period model to a worldwide multiregional model. It is the third research tool of the Standard PEP Model project that emerged spontaneously from the friendship and long-standing association between the co-authors. With this model, we pursue the goals that we had initially set ourselves: to crystallize our joint CGE modeling experience, and to share the result with the PEP MPIA Network, and with the modeling community at large. In addition, PEP-w-1 is another step towards a deepening of our understanding of CGE analysis and the development modeling techniques that will tackle new problems.In a sense, however, PEP-w-1 is a transitional model, a stepping stone towards the recursive dynamic PEP-w-t, and its successor PEP-w-t-F, with international financial assets. As a matter of fact, the authors have already presented the first version of PEP-w-t-F at the Thirteenth Annual Conference on Global Economic Analysis, Penang, Malaysia, June 9-11, 2010 (Lemelin et al., 2010).As usual, we have tried to eliminate as many errors and « misprints » as possible in this document. Needless to say, we welcome comments that will help us improve either the model or its presentation.
