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 and sell to downstream buyers and final demand. Larger firm size can come from high production capability, more or better buyers and suppliers, and/or better matches between buyers and suppliers. Downstream...

This paper studies the role of firm boundaries in how firm-level demand shocks transmit across firm-to-firm networks.

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 supply inputs to each buyer and build a model in which they charge different markups to different buyers. We use the estimated model to quantify how distortionary firm-to-firm markups are. Reducing all markups in firm-t...

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 develop a tractable model of endogenous network formation, allowing firm-to-firm connections to form or break in response to import price changes. Quantitatively, we find that for small import price changes,...

Using a novel comprehensive data set of IT investment at the firm level, we find that a firm investing an additional euro in IT increases value added by 1 euro and 38 cents on average. This marginal product of IT investment increases with firm size and varies across sectors. IT explains about 10% of productivity dispersion across firms. While we find substantial returns of IT at the firm level, such returns are much lower at the aggregate level. This is due to underinvestment in IT (IT capital d...

This paper provides an estimation of the reaction of the 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 elasticity may be affected by firm-level productivity, and how the heterogeneous reaction of different firms may contribute to shape the aggregate reaction of countries’ exports. The analysis relies on a uni...
