Recent quantitative trade models treat import tariffs as pure cost shifters so that their effects are similar to iceberg trade costs. We introduce revenue-generating import tariffs, which act as demand shifters, into the framework of Arkolakis, Costinot and Rodriguez-Clare (2012), and generalize...

We present a factor-proportions trade model in which heterogeneous firms can offshore intermediate inputs subject to fixed offshoring costs. In the skill-abundant country, high-productivity firms offshore a larger range of labor-intensive inputs to the labor-abundant countries than...

Why is it that exporter productivity premia (EPP) differ so widely in size? We take this question to the theory and to the data. We derive the sectoral EPP in a standard heterogeneous firms trade model and apply the insights from the model to 13 years of data for all Danish manufacturing firms....

This paper introduces quality innovations with endogenous sunk costs in a heterogeneous firm model of international trade and derives implications for the gravity equation. The model predicts that the effect of fixed costs on exports and on the share of exporters is lower in industries with a...

An astonishing 33% of all firm-product-destination export spells in Danish data turn out to be isolated single-month one-off export events (observed once in a 49 month window). On average, for an export-active firm, such one-off exports account for 17% of total foreign sales. These patterns...

We set up a model of offshoring with heterogeneous producers that captures two empirical regularities of German offshoring firms. There is selection of larger, more productive firms into offshoring. However, the selection is not sharp, and offshoring and non-offshoring firms coexist over a wide...

This paper documents the importance of consumer taste in trade flows using Belgian firm-product customs data by destination. We identify consumer taste through the use of a control function approach and estimate it jointly with other demand parameters using a very flexible demand specification....

Combining administrative data on German workers with commercial data on German firms, we find evidence for a distance effect on the multinational wage premium: Foreign multinationals pay lower wages than German multinationals if the ultimate owner is located in close proximity to Germany,...

We use a panel of Brazilian exporters, their products, and destination markets to document a set of regularities for multi-product exporters: (i) few top-selling products account for the bulk of a firm's exports in a market, (ii) the distribution of exporter scope (the number of products per...

In this paper, we merge the heterogenous firm trade model of Melitz (2003) with the Ricardian model of Dornbusch, Fisher and Samuelson (DFS 1977) to explain how the pattern of international specialization and trade is determined by the interaction of comparative advantage, economies of scale,...
