This paper studies the growth of Chinese imports into the United States from autarky during 1950-1970 to about 15 percent of overall imports in 2008, taking advantage of the rich heterogeneity in trade policy and trade growth across products during this period. Central to the analysis is an...

This paper studies the effects on international trade from the annual tariff uncertainty about China's Most Favored Nation (MFN) status renewal in the United States prior to joining the World Trade Organization. The paper makes four main findings. First, in monthly data trade increases...

This paper studies the aggregate effects of supply chain disruptions in the post-pandemic period in a heterogeneous-firm, general equilibrium model with input-output linkages and a rich set of supply chain frictions: uncertain shipping delays, fixed order costs, and storage costs. Firms...

Fixed transaction costs and delivery lags are important costs of international trade. These costs lead firms to import infrequently and hold substantially larger inventories of imported goods than domestic goods. Using multiple sources of data, we document these facts. We then show that a...

The extent and direction of causation between micro volatility and business cycles are debated. We examine, empirically and theoretically, the source and effects of fluctuations in the dispersion of producer- level sales and production over the business cycle. On the theoretical side, we study...

We document that international transactions for narrowly defined goods occur infrequently. We study the implications of this lumpiness of international trade for the response of prices and quantities during large devaluations. Using a calibrated inventory management model of international trade...

This paper examines the role of inventories in the decline of production, trade, and expenditures in the United States in the economic crisis of late 2008 and 2009. Empirically, the paper shows that international trade declined more drastically than trade-weighted production or absorption and...

Superseded by Working Paper 12-20 ; The authors study the rise in U.S. manufacturing exports from 1987 to 2002 through the lens of a monopolistically competitive model with heterogeneous producers and sunk costs of exporting. Using the model, they infer that iceberg costs fell nearly 27 percent...

The authors study the effects of tariffs in a dynamic variation of the Melitz (2003) model, a monopolistically competitive model with heterogeneity in productivity across establishments and fixed costs of exporting. With fixed costs of starting to export that are on average 3.7 times as large as...
