Customs data reveal heterogeneity and granularity of relationships among buyers and sellers. A key insight is how more exports to a destination break down into more firms selling there and more buyers per exporter. We develop a quantitative general equilibrium model of firm-to-firm matching...

In the current global context marked by economic fragility, growing uncertainty and geopolitical conflicts, ensuring the smooth functioning of global supply chains becomes more important than ever. Supply shortages, higher freight costs, higher commodity prices and strong demand increase will...

We use the 2018-2019 U.S. trade war to examine how supply chains adjustments to a tariff cost shock affect imports and exports. Using confidential firm-trade linked data, we show that the decline in imports of tariffed goods was driven by discontinuations of U.S. buyer-foreign supplier...

This article documents that antidumping (AD) “echoing” (i.e., different countries sequentially imposing AD measures on the same product from the same exporter) is common practice among users of AD. We develop a dynamic game where two competing importers can impose AD measures on a third...

We develop a dynamic model of international business-to-business transactions in which sellers and buyers search for each other, with the probability of a match depending on both individual and aggregate search effort. Fit to customs records on U.S. apparel imports, the model captures key...

We develop a quantitative general equilibrium model of firm-to-firm matching that...

Official international trade statistics report commerce between every pair of countries twice: once for the importing country and once for the exporter. In principle, the two values differ only by transport costs, but as has long been recognized, they also differ systematically with...

The vast majority of world trade flows is between firms. Only recently has research in international trade started to emphasize the importance of the connections between exporters and importers both in aggregate trade flows and in the negative relationship between trade and geographic distance....

Relationships between firms and their foreign suppliers are the foundation of international trade, but data limitations and reliability concerns make studying such relationships challenging. We evaluate and enhance supplier information in U.S. import data and present new facts about...

Based on extensive interviews with informal importers and brokers in Cameroon, this paper explains why customs reform aimed at reducing fraud and corruption may be difficult to achieve. Informal traders and brokers (without licenses) follow various business models and practices, which are...

Chapter 1. Introduction: Africa’s Piece of the Global Textile Puzzle -- Chapter 2. An Industry Vanishes: Cotton Cloth Manufacturing in Malawi’s Lower Shire Valley, 1850-1930 -- Chapter 3. Rise of the Coastal Consumer: Coast-Side Drivers of East Africa’s Cotton Cloth Imports, 1830-1900 --...

Cotton textile industries vanished from much of East Africa during the nineteenth and early twentieth centuries. This book investigates the underlying causes of industrial arrest in the region through a series of in-depth case studies. Findings are considered in light of existing studies on...

In official international trade statistics, annual commerce between every pair of countries is reported twice: once by the importing country and once by the exporter. These double reports provide an opportunity for audit. In principle, the two reported trade values should differ systematically...

Empirical studies of firms within industries consistently report substantial heterogeneity in measures of performance such as size and productivity. This paper explores the consequences of joint heterogeneity on the supply side (sellers) and the demand side (buyers) in international trade using...

This paper develops a structural macroeconometric model of the world economy, disaggregated into thirty five national economies. This panel unobserved components model encompasses an approximate linear panel dynamic stochastic general equilibrium model featuring a monetary transmission...

In Germany, for the reporting year 2009 transaction-level data on exports and imports of goods have been aggregated at the level of the exporting or importing firm for the first time. In these data the number of goods exported and imported and the number of countries exported to and imported...

We investigate the relationship between exporting, importing, and wage premia using a rich matched employer-employee data set. We improve on the previous literature (i) by using a new methodology to quantify the contribution of an extensive set of worker- and firm-level observable and...

It is widely agreed that a fiscal rule should boost discipline and credibility, reduce macroeconomic volatility, and be easily understood. To support such goals, a government may run structural surpluses and accumulate a precautionary cushion of assets on behalf of agents who do not enjoy access...

This paper documents that intermediaries play an important role in facilitating international trade. We modify a heterogeneous firm model to allow for an intermediary sector. The model predicts that firms will endogenously select their mode of export-either directly or indirectly through an...

This paper considers the effects of trade policy--tariffs and quotas--when importing is done by competitive traders who are identical ex ante but differ ex post. We show that the standard equivalence results no longer hold and the conventional ranking of tariffs and quotas is turned on its head:...

We provide systematic evidence that intermediaries play an important role in facilitating trade using a firm-level the census of China's exports. Intermediaries account for around 20% of China's exports in 2005. This implies that many firms engage in trade without directly exporting products. We...
