Global Simulation Analysis of Industry-Level Trade Policy: the GSIM model

This technical report brings together two papers on the linear and non-linear versions of the multi-region trade simulation model known as GSIM. It outlines a modeling strategy for the partial equilibrium analysis of tariff and antidumping policy on a global level. The framework is scalable, employs national product differentiation, and allows for the simultaneous assessment of trade policy changes (duties and undertakings), at the industry level, on a global, regional, or national level. Results allow the assessment of importer and exporter effects related to tariff revenues, exporter (producer) surplus, and importer (consumer) surplus. With additional data, national employment effects can also be fit into the basic framework. NOTE the *.zip archive includes Excel template models, and the technical papers that explain the model.
