Using a detailed data set at the tariff line level, we find an emulator effect of multilateralism on subsequent regional trade agreements involving the US. We exploit the variation in the frequency with which the US has granted immediate duty free access (IDA) to its Free Trade Area partners...

This paper studies the impact of NAFTA on informality and real wages in Mexico. Using a dynamic industry model with firm heterogeneity, it is predicted that import tariff elimination could reduce the incidence of informality by making more profitable to some firms to enter the formal sector,...

This paper reviews the empirical evidence on firm heterogeneity in international trade. A first wave of empirical findings from micro data on plants and firms proposed challenges for existing models of inter- national trade and inspired the development of new theories emphasizing firm...

Firms face competing needs to expand product variety and reduce production costs. Trade policy affects firm investments in product variety and production processes differently. Access to larger markets enables innovation to reduce costs. Although firm scale increases, foreign competition reduces...

International trade models typically assume that producers in one country trade directly with final consumers in another. In reality, of course, trade can involve long chains of potentially independent actors who move goods through wholesale and retail distribution networks. These networks...

This paper reviews the new approach to international trade based on firm heterogeneity in differentiated product markets. This approach explains a variety of features exhibited in disaggregated trade data, including the higher productivity of exporters relative to non-exporters, within-industry...

This paper analyses the interaction between credit constraints and trading behaviour. I construct a unique dataset containing firm-level trade transactions data, balance sheets and credit scores from an independent credit insurance company for Belgian manufacturing firms between 1999 and 2007....

Using a novel dataset with transactions level exports data from four African countries (Malawi, Mali, Senegal and Tanzania), this paper uncovers evidence of a high degree of experimentation at the extensive margin associated with low survival rates, consistent with high and middle income country...

We provide an analysis of the 2008-2009 trade collapse using microdata from a small open economy, Belgium. First, we find that changes in firm-country-product exports and imports occurred mostly at the intensive margin: the number of firms, the average number of destination and origin markets...

The paper explores the determinants of industry location across interwar Poland. After more than 120 years ofpolitical and economic separation, Poland was reunified at the end of 1918. In consequence, its industry facedmassive structural changes: the removal of internal tariff barriers and...
