This technical Appendix describes the structural model used as part of the Spatial Eco- nomic Research Centre's work for the Northern Way on linkages between the Manchester and Leeds City Regions. A summary of the research, as well as a full report of the findings, can be found on the web-sites...

We develop a new general equilibrium monopolistic competition model with variable demand elasticity, heterogeneous firms, and multiple asymmetric regions. Wages, productivity, consumption diversity, and markups across firms and markets are all endogenously determined and respond to trade...

While it is well established that across-country taste differences are associated with "home market effects", there is very limited analysis of how such preference heterogeneity impacts the aggregate volume of trade and the welfare gains from liberalization. I develop a structural model of...

Using a detailed database on intra-MERCOSUR tariffs, we estimate the effect of tariff preferences on the origin of imports of MERCOSUR members. The results show tariff preferences affected imports patterns in the cases of Argentina and Uruguay, and to a less extent also those of Brazil. For the...

The dynamics of export market exit and firm closure have found limited attention in the new heterogeneous-firms trade literature. In fact, several of the predictions on firm survival and exit stemming from this new class of models are at odds with the stylized facts. Empirically, higher...

We develop a new general equilibrium model of monopolistic competition with heterogeneous firms, variable demand elasticity and multiple asymmetric regions, in which trade integration induces wage and productivity changes. Using Canada-US interregional trade data, we structurally estimate a...

This paper shows that the novel gains from trade liberalization driven by intra-industry reallocations (Melitz (2003)) are not robust to changes in the preference structure. In the Melitz (2003) setting the unambigousness of the welfare effect depends crucially on the assumption of traditional...

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models. However, these models tend to rely heavily on symmetry assumptions and assume melting iceberg transport costs as the only form of trade restrictions. Moreover, a standard...

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models. This introduction has highlighted the importance of the entry/exit decision of firms in response to changes in trade barriers. However, it is typical in many of these...
