The conclusions of the 1976 Kemp-Van proposition are shown to be substantially valid even if all tariff vectors, both pre-union and post-union, are optimally chosen.

A model of heterogeneous firms with variety-specific fixed costs is developed and analyzed to study how multiproduct firms respond to globalization. In contrast with most existing models, the analysis demonstrates that more-productive firms may expand their product scope, which in turn may push...

This paper provides a theoretical and empirical analysis of the effects of one-sided tariff cuts on firms’ export product scope. The theoretical model explicitly incorporates cost of management in addition to the commonly used production cost. The analysis predicts that the home country’s...

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 paper presents a new and simple heterogeneous-firms specification. We develop a symmetric...
