We use Belgian data with information on domestic firm-to-firm sales and foreign trade transactions to study how international trade affects firms' unit cost and the consumer's real wage. We show theoretically that the gains from trade depend on domestic firm-to-firm linkages. Furthermore, we...

This paper quantifies the origins of firm size heterogeneity when firms are interconnected in a production network. Using the universe of buyer-supplier relationships in Belgium, the paper develops a set of stylized facts that motivate a model in which firms buy inputs from upstream suppliers...

This paper studies the implications of imperfect competition in firm-to-firm trade. Exploiting data on the universe of sales relationships between Belgian firms, we document that firms' markups increase in the average input shares among their buyers. Given this fact, we develop a model where...

We examine how many and what kind of firms ultimately rely on foreign inputs, sell to foreign markets, and are affected by trade shocks. To capture that firms can trade indirectly by buying from or selling to domestic firms that import or export, we use Belgian data with information on both...

This paper provides a new cross-country evaluation of competitiveness, focusing on the linkages between productivity and export performance among European economies. We use the information compiled in the Trade module of CompNet to establish new stylized facts regarding the joint distributions...

This paper provides an estimation of the reaction of firm-level exports consecutive to real exchange rate movements, the exchange rate elasticity of exports. Following recent theoretical works emphasizing the role played by firm heterogeneity, we test in particular how the exchange rate...

Whilst overall productivity growth is stalling, firms at the frontier are still able to capture the benefits of the newest technologies and business practices. This paper uses linked employer-employee data covering all Belgian firms over a period of almost 20 years and investigates the...
