This presentation consists of four sections that describe a PEP 1-t model. The first section covers a general overview of the PEP 1-t model, including multi-sector, national model, recursive dynamic framework, multiple labor and capital categories, tax instruments, and compatible with rectangular input-output tables. The second section reviews all files related to this PEP 1-t model. The third section describes the mathematical structure of the module, GAMS codes, SAM, technical description, user guide, and pedagogical material. The last two sections provide the SAM and GAMS code in detail. You can find more information about the model here.
