Computable general equilibrium (CGE) models have become a widespread method to assess economy-wide and sectoral impacts of trade policies. While the results of simulations with these models depend on a number of inputs, trade elasticities are of particular interest because of their significant impact on modeled trade patterns, welfare and factor returns. Our objective is to implement and evaluate, within the context of a CGE model, an up-to-date set of trade elasticities, and investigate the role of these parameters in key trade policy modelling uncertainties.
