This paper demonstrates that deviations from the law of one price are an important source of violations of absolute PPP across countries. Using highly disaggregated U.S. export data, we document evidence of systematic international price discrimination based on the local wage of consumers in the...

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 authors show that deviations from the law of one price in tradable goods are an important source of violations of absolute PPP across countries. Using highly disaggregated export data, they document systematic international price discrimination: at the U.S. dock, U.S. exporters ship the same...

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 can not be explained in standard models by either changes in expenditures or relative prices are often attributed to trade wedges. We show that these trade wedges can reflect the decisions of importers to change their inventory...
