Armington Meets Melitz: Introducing Firm Heterogeneity in a Global CGE Model of Trade
AbstractTraditional CGE models with Armington assumption fail to capture the extensive margin of trade, thereby underestimate the trade and welfare effects of trade opening. To address this problem, this paper introduces the Melitz (2003) theoretical framework with firm heterogeneity and fixed exporting costs into a global CGE model. Some illustrative simulations show that the introduction of firm heterogeneity improves the ability of CGE model to capture the trade expansion and welfare effects of trade liberalization. Under the case of global manufacturing tariff cut, the estimated gains in welfare and exports are more than double that obtained from the standard Armington CGE model. Sensitivity analysis indicates that model results are sensitive to the shape parameters of firm productivity distribution, suggesting the need of further empirical work to estimate the degree of firm heterogeneity.
