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...

In order to develop trade in services, the GATS aims to eliminate progressively discriminatory regulations, which apply to foreign suppliers. This paper looks instead at the trade effect of domestic regulations, which apply to all firms indifferently and do not intend to exclude imports. We...

Firm-level regressions show that Champagne producers that receive better ratings from wine guides also export to more markets, charge higher prices, and sell more in each market. Our method corrects for a severe selection bias predicted by the model. By using direct measures of quality, we can...

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...

The story of deindustrialization of developed economies is now old and well-observed. In most developed countries, value added by manufacturing as a percentage of GDP has decreased continuously since the 1950's, and is now less than 15% in most OECD countries. The shift of value added and...

Recent empirical research in international trade has revealed overwhelming evidence that, in all countries, a remarkably small proportion of firms report exports in Customs statistics. A large share of these are wholesalers. This suggests that the number of firms active in foreign markets might...

Guided by empirical evidence we consider firms heterogeneity in terms of factor intensity. We show that Heckscher-Ohlin comparative advantage and firm-level relative factor-intensity interact to jointly explain the observed differences in relative sales. Firms whose relative factor-intensity...
