"GTAP model v7 in Julia" by Ivanic, Maros Abstract I introduce a formulation of the GTAP version 7 model in an open-source language, Julia, that closely follows the specification of the model in GEMPACK, including equation and variable names. Unlike the linearized GEMPACK version, my formulation is in levels. I show that my model produces nearly identical results with differences at or beyond the fifth significant digit. Because the model is expressed in levels, it is able to address a wider range of policy questions, especially those that are not suitable for perturbation assessment, such as simulations involving parameter changes or new value flows. My formulation of the GTAP model is quite different from the earlier formulation in levels in GAMS (Mensbrugghe 2018), commercial software, which does not follow the nomenclature of the GTAP model in GEMPACK and also requires a software license, making it more difficult for the GEMPACK users to transition to. |
