In this paper we study how the trade costs and the intensity of competition can explain the existence of bilateral trade, unilateral trade and no trade within an industry. We show as trade costs decrease from very high to very low values, the global economy moves from autarky to a regime of...

In this paper we build an economic geography model where firms sell product varieties with heterogenous demands. We show that firms selling the products with higher demands select to set up their plants in larger countries. Larger countries do not only get better access to more varieties but...

We study how the level of trade costs and the intensity of competition interact to explain the nature and intensity of trade within a given industry and the location of firms across countries. As trade costs decrease from very high to very low values, the global economy moves from autarky to...

The aim of this paper is to study the spatial selection of firms once it is recognized that heterogeneous firms typically choose different locations in respond to market integration of regions having different sizes. Specifically, we show that decreasing trade costs leads to the gradual...

We study how the level of trade costs and the intensity of competition can explain the existence of two-way, one-way or no trade within the same industry. As trade costs decrease from very high to very low values, the economy moves from autarky to a regime of two-way trade, through a regime of...

We show that heterogeneous firms choose different locations in response to market integration. Specifically, decreasing trade costs lead to the gradual agglomeration of efficient firms in the larger country where they have access to a bigger pool of consumers. In contrast, high-cost firms seek...
