We study the aggregate implications of production network formation in a quantitative multi-location general equilibrium trade model. Firms search for suppliers and buyers across locations subject to matching frictions, generating a gravity structure of production networks. We develop sufficient...

We study the gains from trade liberalization in models with monopolistic competition, firm-level heterogeneity, and variable markups. For a large class of demand functions used in the international macro and trade literature, we derive a parsimonious generalization of the welfare formula in...

We explore the implications of models with increasing returns, endogenous variety and firm-level heterogeneity for the quantification of the gains from trade. We first focus on the impact of trade liberalization on imported variety by analyzing the experience of Costa Rica from 1986 to 1992. We...
