We build a theoretical model of multi-product firms that highlights how competition across market destinations affects both a firm's exported product range and product mix. We show how tougher competition in an export market induces a firm to skew its export sales towards its best performing...

Quantifications of gains from trade in heterogeneous firm models assume that productivity is Pareto distributed. Replacing this assumption with log-normal heterogeneity retains some useful Pareto features, while providing a substantially better fit to sales distributions-especially in the left...

This article analyzes empirically the relationship between civil wars and international trade. We first show that trade destruction due to civil wars is very large and persistent and increases with the severity of the conflict. We then identify two effects that trade can have on the risk of...

This paper identifies the causal impact of urban rail transport on firm location. The evaluation of transport infrastructures always faces an important issue of endogeneity since rail lines are not randomly located. We use the natural experiment offered by the Regional Express Rail (RER) in the...

Recent theoretical work on economic geography emphasizes the interplay of transport costs and plant-level increasing returns. In these models, the spatial distribution of demand is a key determinant of economic outcomes. In one strand, it is argued that higher demand gives rise to a more than...

Using data on name distributions in 95 French d'epartements observed from 1946 to 2002, we investigate spatial and social mechanisms behind the transmission of parental preferences. Drawing inspiration from recent work on social interactions, we develop a simple discrete choice model that...

In addition to standard trade gains, regional trade agreements (RTAs) can promote peaceful relations by increasing the opportunity cost of conflicts. Country pairs with large trade gains from RTAs and a high probability of conflict should be more likely to sign an RTA. Using data from 1950 to...

Clusters have already been extensively shown to favor firm-level economic performance (productivity, exports, innovation etc.). However, little is known about the capacity of firms in clusters to resist economic shocks. In this paper, we analyze whether firms that agglomerate in clusters and...
