We show that the negative impact of financial crises on trade is magnified for destinations with longer time-to-ship. A simple model where exporters react to an increase in the probability of default of importers by increasing their export price and decreasing their export volumes to...

This paper analyzes the reaction of exporters to exchange rate changes.We present a model where, in the presence of distribution costs in the export market, high and low productivity firms react differently to a depreciation. Whereas high productivity firms optimally raise their markup rather...

We build a theoretical model of multi-product firms that highlights how market size and geography (the market sizes of and bilateral economic distances to trading partners) affect both a firm’s exported product range and its exported product mix across market destinations (the distribution of...

This paper analyzes empirically the effect of spatial agglomeration of activities on plant-level productivity, using French firm and plant-level data from 1996 to 2004. We exploit short-run variations of variables by making use of GMM estimation. This allows us to control for endogeneity biases...

This paper analyzes empirically a public policy promoting industrial clusters in France. Cluster policies have become popular in many countries but have not been extensively evaluated. We propose in this paper the first quantitative evaluation of a cluster policy exploiting firm-level data. We...

This paper analyses theoretically and empirically the relationship between trade and war. We show that the intuition that trade promotes peace is only partially true even in a model where trade is beneficial to all, war reduces trade and leaders take into account the costs of war. When war can...

Le commerce international n'est pas toujours un facteur de pacification des relations entre les pays. Certes, si deux pays commercent davantage de manière bilatérale, ils sont plus fortement incités à résoudre pacifiquement le conflit qui peut les opposer. Mais s'ils commercent davantage...

Le 12 juillet 2005, le gouvernement a labellisé 67 « pôles de compétitivité » ou clusters. Ils sont aujourd'hui au nombre de 71. La politique d'aménagement du territoire est passée d'une intervention publique destinée à aider les régions en difficulté à une politique visant à...

We analyze the interaction of economic and political determinants of free trade agreements (FTA). In addition to standard trade gains, FTAs can promote peaceful relations by offering a political forum and by increasing the opportunity cost of conflicts that disrupt trade. If policy makers...
