In this paper, we merge the heterogenous firm trade model of Melitz (2003) with the Ricardian model of Dornbusch, Fisher and Samuelson (DFS 1977) to explain how the pattern of international specialization and trade is determined by the interaction of comparative advantage, economies of scale,...

What has been the overall global welfare impact of the accession to the World Trade Organization of a large country like China, or the global welfare impact of the completion of the Uruguay round of GATT negotiations? Can we come up with a simple user-friendly formula to calculate the global...

In this paper, we incorporate Ricardian comparative advantage into a multi-sector version of Melitz's (2003) model to explain the pattern of international specialization and trade. The model is able to capture the existence of inter-industry trade and intra-industry trade in a single unified...

The literature on trade liberalization has recently shifted its attention from trade liberalization in imported final goods to studying the effects of trade liberalization in imported intermediate inputs. This emphasis fits very well the trade liberalization experience of China following its...

This paper develops a monopolistic competition model of multiproductfirms to explain the effect of trade liberalization on the product mix of multiproductexporting firms. The model shows that input-tariff reduction leads to increasesin a firm’s export values, especially for products that are...

This paper presents theory and evidence from highly disaggregated Chinese data that tighter credit constrains force firms to produce lower quality. The paper modifies Melitz's (2003) model of trade with heterogeneous firms by introducing quality choice and credit constraints. The quality sorting...
