This paper discusses which changes in the architecture of a standard CGE model are needed in order to introduce effects of trade and firm heterogeneity à la Melitz. Starting from a simple specification with partial equilibrium, one primary production factor and one industry, the framework is...

This paper analyzes the qualitative properties of a multisectoral, multiregional computable general equilibrium model where some industries include heterogeneous firms as in Melitz (2003). The model, formulated according to Roson and Oyamada (2014), adds endogenous productivity effects to a...

The aim of this work is analyzing the practical relevance, from a qualitative perspective, of a new methodology which is intended to include firm heterogeneity, as modeled by Melitz (2003), in computable general equilibrium effects. We assess to what extent the inclusion of industries with...
