P4: Extended 1*2*3 (Open Economy) CGE Model


This module extends the basic 1*2*3 model by adding policy instruments so that the model can be used to conduct policy analyses. The principles followed are based on work by Deverajan, Go, Robinson that was implemented by the World Bank in the late 1990s. The data used are derived from an augmented version of the GTAP database.
