The concept of virtual water refers to the volume of water used in the production of a commodity or a service. The concept was identified by the geographer Tony Allan in the early 1990s, to draw attention on the global economic processes that ameliorate local water deficits in the MENA region...

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, R. and Oyamada (2014), adds endogenous productivity effects to a...

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...
