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...

Trade unit values are commonly used as proxies for trade prices in empirical research in international economics. Existing datasets providing international trade unit values for a large number of countries typically suffer from a number of statistical biases, due to the aggregation of unit...

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...

This paper documents the construction of BACI, our international trade database, which covers more than 200 countries and 5,000 products, between 1994 and 2007. New approaches have been developed to reconcile data reported by almost 150 countries to the United Nations Statistics Division,...

Evasion of customs duties is a serious concern in developing countries, where tariff receipts are often important, but their collection is often problematic. We study theoretically and empirically the determinants of evasion across countries and products, based on a systematic analysis of...

The sub-Saharan African (SSA) countries are excluded from the mega-deals (EU-USA, EU-Japan, China-Japan-Korea…) under negotiations: they might however undergo important economic impacts, as their exports remain dependant from those large markets. Using a dynamic Computable General Equilibrium...

Methodological issues arising from the estimation of tariff equivalents of barriers to services trade are very relevant for policy. These equivalents are used extensively to compute welfare gains and resource reallocations associated with partial liberalization of the sector; any measurement...

Using a dynamic computable general equilibrium model of the world economy (MIRAGE), we simulate the impacts of the most recent drafts circulated in the multilateral trade negotiations arena, augmented by a modest outcome of the negotiation in services. The liberalisation of tariffs is...

GeoDist makes available the exhaustive set of gravity variables used in Mayer and Zignago (2005). GeoDist provides several geographical variables, in particular bilateral distances measured using citylevel data to assess the geographic distribution of population inside each nation. We have...

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...
