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...

The large, persistent fluctuations in international trade that cannot be explained in standard models by changes in expenditures and relative prices are often attributed to trade wedges. We show that these trade wedges can reflect the decisions of importers to change their inventory holdings. We...

We study empirically and theoretically the growth of U.S. manufacturing exports from 1987 to 2007. We identify the change in iceberg costs with plant-level data on the intensity of exporting by exporters. Given this change in iceberg costs, we find that a GE model with heterogeneous...

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...

We study the role of inventories for the volatility of international trade and the propagation of business cycles. We build a model of international trade in which intermediaries have a precautionary motive to hold inventories. With either productivity or demand shocks, we find inventories...
