Recent literature on the workhorse model of intra-industry trade has explored heterogeneous cost structures at the firm level. These approaches have proven to add realism and predictive power. This note shows, however, that this added realism also implies that there may exist a positive...

This paper develops a theory of strategic vertical DFI (direct foreign investment) to suggest an explanation for the empirical puzzle of the missing `pollution-haven' effect. It focuses on a firm's strategic incentive to create multi-market interdependence (in addition to other conventional...

The paper proposes a model to investigate the influences of agglomeration on heterogeneous firms' exporting behaviors. In the model, firms are heterogeneous in productivity. Selection effect and agglomeration economies caused by agglomeration increase firms' productivity and decreases industrial...

Yet, in a number of policy fields,...

This paper investigates Samuelson's (JEP, 2004) argument that technical progress of the trade partner may hurt the home country. We illustrate this prospect in a simple Ricardian model for sitations with outward knowledge spillovers. Within this framework Samuelson's Act II effects may occur....
