New empirical and theoretical work has highlighted the importance of multi-product firms in international tradeflows. We examine multi-product exporters in the small open economy of Belgium, considering their importance and the relationship between the margins of trade and firm productivity,...

Large multi-product firms dominate international trade flows. This paper documents new facts about multi-product manufacturing exporters that are not easily reconciled with existing multi-product models. Using novel linked production and export data at the firm-product level, we find that the...

This paper develops a model where firms across countries differ in their capacity to innovate. Our main goal is to study firm level innovation under various trade policy shocks. We consider two countries where firms across countries are heterogeneous in their innovation efficiencies. We find...

We develop a North-South model of reciprocal antidumping (AD). We find that AD wars are winnable for the Northern firm if the Southern market is sufficiently small relative to the North’s. The South can avert AD war with the North by expanding the home market size. It may however trigger AD...

The recent availability of trade data at a firm-product-country level calls for a new generation of models able to exploit the large variability detected across observations. By developing a model of monopolistic competition in which varieties enter preferences non-symmetrically, we show how...
