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...

High-performance firms typically have two features in common: i) they produce in more than one country and ii) they produce more than one product. In this paper, we analyze the internationalization strategies of multi-product firms at the product-level. We find that the most productive firms...

We address the mismatch between existing theoretical models and standard empirical practice in the analysis of the labor market effects of offshoring. While theory focuses on one-sector or two-sector models, empirical studies exploit variation in offshoring across a large number of industries,...

This paper formulates a structural empirical model of heterogeneous firms whose workers exhibit fair-wage preferences. In the underlying theoretical framework, such preferences lead to a link between a firm's operating profits on the one hand and wages of workers employed by this firm on the...

This paper analyzes how exporters are affected by corporate tax reforms in destination markets. We introduce tax policy in a trade model of multi-product firms and show that producers face tougher competition in export markets with lower corporate tax rates. This competitive effect induces firms...

This paper investigates the effects of mergers on the product mix of multiproduct firms. Thus, we open the black box of post-merger efficiency improvements to reveal a new margin of adjustment along the product dimension. We analyze horizontal mergers in a theoretical model where oligopolistic...

We challenge the common practice of estimating gravity equations with time-interval data in order to capture dynamic-adjustment effects to trade-policy changes. Instead, we point to a series of advantages of using consecutive-year data recognizing dynamic-adjustment effects. Our analysis reveals...
