We use Belgian data with information on domestic firm-to-firm sales and foreign trade transactions to study how international trade affects firm efficiency and real wages. The data allow us to accurately construct the domestic production network of the Belgian economy, revealing several new...

This paper evaluates how firms change their prices in response to cost shocks and other price changes in their environment. We first document three new facts on the heterogeneity of firm-level producer prices and their relationship to buyers and suppliers in a production network. We then develop...

Global Value Chains have proliferated economic policy debates. Yet a key concept - trade in value added - is likely mismeasured because of sectoral aggregation bias stemming from reliance on inputoutput tables. This paper uses comprehensive firm-level data on both domestic and international...

This paper uses Business to Business (B2B) transaction level data. It shows that manufacturing firms that initially export via a wholesaler are much more likely to become direct exporters to the same destination in subsequent periods. Theoretically, we rationalise this finding by demonstrating...

This paper studies the implications of imperfect competition in firm-to-firm trade. Using a dataset on all transactions between Belgian firms, we find that firms charge higher markups if they have higher input shares among their buyers. We interpret this as firms competing as oligopolies to...

This paper studies how outsourcing of services activities affects TFP at the firm level. Using the universe of buyer-supplier relationships in Belgium, we first document several new empirical facts about how firms engage in the outsourcing of supporting activities. We show that virtually all...

This paper estimates how the impact of a natural disaster propagates through the production network. More precisely, we look at the excessive rainfall in the summer of 2021 that caused large areas to be severely flooded in Belgium. We first look at the direct effects on firms active in the...

Carbon markets are a central instrument to decarbonise our economies and mitigate the impacts of climate change. Within the European Union, carbon pricing to date has primarily targeted electricity generation and greenhouse gas-intensive industries, and regulatory focus has typically been...

This study provides a detailed and easy-to read overview of the railway liberalisation in Belgium and the three neighbouring countries. The European Union's liberalisation Directives are often complex and are implemented in very specific ways in the different Member States. The analysis goes...

We study the role of contract enforcement in shaping the dynamics of international trade at the firm level. We develop a theoretical model to describe how agents build reputations to overcome the problems created by weak enforcement of international contracts. We find that, all else equal,...
