In recent years empirical studies offer clear evidence on the increasing importance of intra-industry trade in presence of vertically differentiated products. These are goods that, within the same industry, are distinguished by different quality levels. In the new trade theory and in the...

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...

The article summarises the main lessons of the Bank’s 2010 conference which focused on international trade and foreign direct investment. The research is based on a microeconomic approach to the behaviour of Belgian firms, with reference to developments in the scientific literature on the...

This article reviews the recent theoretical literature on heterogeneous firms and trade, which emphasizes firm selection into international markets and reallocations of resources across firms. We discuss the empirical challenges that motivated this research and its relationship to traditional...

Recent quantitative trade models treat import tariffs as pure cost shifters so that their effects are similar to iceberg trade costs. We introduce revenue-generating import tariffs, which act as demand shifters, into the framework of Arkolakis, Costinot and Rodriguez-Clare (2012), and generalize...

This paper questions whether the overseas expansion of a country’s retailers fosters overall bilateral exports towards these host markets. To address this question, we consider an empirical trade model, where the foreign sales of multinational retailers reduce the fixed and variable trade...

We use unique plant-level data to study the link between the local availability of services and the decision of manufacturing firms to source materials from abroad. To guide our empirical analysis we develop a monopolistic-competition model of the materials sourcing decisions of heterogeneous...

Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on international trade flows, and the well-known - and traditionally presumed exogenous – “trade-cost elasticity” plays a central role in computing general equilibrium trade-flow...
