Recent trade models with heterogenous firms have considerable consequences on the interpretation of gravity equations. Chaney (2008) shows that the effect of distance on trade margins incorporates three parameters: the elasticity of substitution between goods, the elasticity of trade costs with...

This paper analyses the trade effects of restrictive product standards on the margins of trade for a large panel of French firms. To focus on restrictive product standards only, we use a new database compiling the list of measures that have been raised as concerns in dedicated committees of the...

In this paper we develop a three-country monopolistic competition model with variable elasticity of substitution and vertical linkages to study the impact of trade liberalization on trade creation, trade diversion and labor market outcomes. This framework allows us to identify a source of gain...

We investigate the effect of different channels through which input trade liberalization affects firms’ export decisions. We develop a trade model with heterogeneous firms and sectors of varying imported input intensity that reproduces different mechanisms through which the access to foreign...

This paper proposes an original approach to investigate the influence of insecurity and institutional quality on international trade. We emphasize that insecurity is hardly comparable with other trade barriers such as tariffs because it does not affect all firms similarly. We develop a...

Why would an increase in imported inputs rise exports? We argue that importing more varieties of intermediate inputs increases firm’s productivity and thereby makes the firm able to overcome the export fixed costs. Whereas the literature evidences the positive effect of an increase in imported...

Within the migration-trade nexus literature, this paper proposes a more carefully defined measure of migration business networks, and quantifies its impact on bilateral trade. Controlling for the overall bilateral stock of migrants, the share of migrants employed in managerial/business-related...
