The basic gains-from-trade theorem makes a stark comparison between completely free trade and complete autarky. This paper is motivated by recent evidence that trade has greatly expanded on the extensive margin (aka fragmentation, offshoring) by adding newly traded goods and services and that...

A number of stylized facts have been documented about the extensive margin of trade - which firms export, and how many products they send to how many destinations. We argue that the sparse nature of trade data is crucial to understanding these stylized facts. Typically the number of observations...

This paper empirically evaluates the effects of antidumping measures on the exports of protected firms. While antidumping protection raises the domestic sales of the more “traditional” non-exporting firms on the protected market with about 5%, it negatively affects the firm-level exports of...

This paper tests whether trade in new goods is partially responsible for the pro-trade effects of the euro and provides a measure of the size of the effect. It works with a very large data set (about 16 million observations) covering twenty countries at the most disaggregated level of trade data...

How successful is the theory of the firm in explaining intra-firm trade? To answer this question we exploit a unique dataset of 1,141,393 French import transactions, spanning across firm, countries and products in 1999, and reporting whether a transaction is intra-firm. Overall, we find support...

This paper studies the extensive and intensive margins of firms' global sourcing decisions. We develop a quantifiable multi-country sourcing model in which heterogeneous firms self-select into importing based on their productivity and country-specific variables. The model delivers a simple...

Firms employ a rich variety of pricing strategies whose implications for aggregate price dynamics often diverge. This situation poses a challenge for macroeconomists interested in bridging micro and macro price stickiness. In responding to this challenge, we note that differences in macro price...

Understanding the development of chainstores is important given the large GDP share of services and the continuing importance of chains in bringing these services to market. Service chains provide a puzzle because they take a long time to develop even when there are obvious expansion...
