We study the effects of tariffs and iceberg trade costs in a two-sector dynamic variation of the Melitz (2003) model extended to include a sunk cost of exporting, establishment-level uncertainty in productivity, capital accumulation, and material usage. We calibrate the model to match both...

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