Using a multi-regional and multi-sectoral model (MIRAGE), this paper attempts to model explicitly trade facilitation in a dynamic computable general equilibrium (CGE) model of the world economy. We use ad valorem equivalents (AVEs) of such barriers computed from a gravity model and introduced in the CGE model. The novelty of those AVEs is that they take into account the effect of bureaucracy, Internet widespread, corruption and geographical barriers on time to trade. My main findings show that, on the regional level, developing countries in Africa and Asia, especially the Middle East and North Africa gain much more from trade facilitation than developed ones. On the sectoral level, food, textiles, electronics and metal products witness a more important expansion than other products.
