Dans un contexte de renchérissement prévisible de l’énergie au cours des vingt prochaines années, orienter l’effort d’innovation industrielle et l’offre de biens et services vers des technologies économes en énergie est une nécessité. Toutefois, une hausse des prix de...

Despite the liberalization of capital flows among OECD countries, equity home bias remains sizable. We depart from the two familiar explanations of equity home bias: transaction costs that impede international diversification, and terms of trade responses to supply shocks that provide risk...

This paper analyzes the determinants of cross-border asset trade on cross-country data and a Swedish data set. We focus our analysis on the impact of the euro for the determinants of trade in bonds, equity and banking assets. With the help of a theoretical model, we disentangle the different...

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 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...

This paper analyses the efficiency and the equity motives that can justify regional policies. The market failure induced by localized technological spillovers entails too little agglomeration. However, coordination failures and the fact that firms do not take into account the welfare of immobile...

European policy makers may have asked too much from regional policies: to decrease inequalities between regions, to increase efficiency at the national and European levels and to decrease inequalities between countries. This paper argues that these policies face a trade-off between equity and...

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 empirically. We use data on production and employment for firms that benefited from the policy and on firms that...

This paper analyzes empirically the effect of spatial agglomeration of activities on the productivity of firms using French individual firm data from 1996 to 2004. This allows us to control for endogeneity biases that the estimation of agglomeration economies typically encounters. French firms...

This paper analyses the welfare implications of international spillovers related to productivity gains, changes in market size, or government spending. We introduce trade costs and endogenous varieties in a two-country general-equilibrium model with monopolistic competition, drawing a...
