This Paper presents a model of international trade that features heterogeneous firms, relative endowment differences across countries, and consumer taste for variety. The Paper demonstrates that firm reactions to trade liberalization generate endogenous Ricardian productivity responses at the...

A large class of models with CES utility and iceberg trade costs are now known to generate isomorphic “gravity equations.” Economic interpretations of these gravity equations vary in terms of two basic elements: the exporter's “mass” variable and the elasticity of trade with respect to...

Small and medium-sized enterprises (SMEs) play an important role in generating economic activity and employment in developing and developed countries. However, partly due to remaining at-the-border trade costs, SMEs continue to be less represented in international trade – as direct exporters...

This paper provides a broad overview of some of the issues that digital trade raises for ASEAN countries and its MSMEs, including new opportunities that digitalisation presents for ASEAN firms to increase trade. However, it shows that adoption of relatively simple digital tools, such as...

This paper explores the combined effects of reductions in trade frictions, tariffs, and firing costs on firm dynamics, job turnover, and wage distributions. It uses establishment-level data from Colombia to estimate an open economy dynamic model that links trade to job flows in a new way. The...

Empirical evidence has shown that exporters are more capital intensive than non-exporters. Based on this evidence, I construct a two-factor general equilibrium model with firm heterogeneity in factor intensities, monopolistic competition, scale economies and international trade. This setting can...

The paper sets up a two-country asymmetric trade model with heterogeneous firms, search frictions and endogenous labor market institutions. Countries are linked by trade in goods and non-cooperatively set unemployment benefits to maximize national welfare. We show that more open and smaller...

Legal systems provide the basic institutions for firms and markets to operate. Their quality can have important consequences on the size distribution of firms, who rely on them for contract enforcement. This paper uses the variation in legal system quality across states in Mexico to examine the...

The field of international trade has undergone significant theoretical and empirical advancements over the last twenty-five years. A key breakthrough has been the emergence of firm-level approaches to studying exporting, importing, and global value chains. The field has also experienced a...

We quantify and explain the firm responses and worker impacts of foreign demand shocks to domestic production networks. To capture that firms can be indirectly exposed to such shocks by buying from or selling to domestic firms that import or export, we use Belgian data with information on both...
