Is the variation in bilateral trade flows across countries primarily due to differences in the number of exporting firms (the extensive margin) or in the average size of an exporter (the intensive margin)? And how does this affect the estimation and quantitative implications of the Melitz (2003)...

This study explores the effect of parallel imports (PIs) when the producer may discriminate repair and maintenance services against PI units. This service discrimination weakens intra-brand competition and reduces the degree of price convergence between countries. If the producer makes costly...

Following the trade collapse in 2009, Globalization has recovered but the growth rate slowed down compared to the preceding period of Hyper Globalization. The persistence of this slowdown is remarkable. We argue that increased awareness of firms for the costs of involvement in global supply...

A striking pattern in transaction-level data is the concentration of international shipments in the hands of a few large firms. One common feature of dominating high-performance firms is that they produce multiple products and ship them to many destinations. Motivated by the emergence of highly...

The recent literature on firm-to-firm trade has documented salient empirical regularities of the buyer-seller network. We propose a simplistic re-interpretation of the classical Krugman (1980) model that accounts for surprisingly many of the empirical regularities. This re-interpretation relies...

This paper provides a direct test of how fixed export costs and productivity jointly determine firm-level export behavior. Using Chilean data, we construct indices of fixed export costs for each industry-region-year triplet and match them to domestic firms. Our empirical results show that firms...

We extend structural gravity models of bilateral trade flows to oligopolistic competition. We show that conventional gravity estimates do not only reflect trade costs but also market power. Our simple estimation procedure generalizes the standard gravity model and disentangles exogenous trade...

In this paper we explore the role that demand uncertainty plays for the offshoring decision, and the role that offshoring plays for domestic volatility of employment. Offshoring is modeled as in Antràs & Helpman (2004), but we assume complete contracts. Firms are heterogeneous as in Melitz...
