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...

This paper examines the role of inventories in the decline of production, trade, and expenditures in the US in the economic crisis of late 2008 and 2009. Empirically, we show that international trade declined more drastically than trade-weighted production or absorption and there was a sizeable...

We show that deviations from the law of one price in tradable goods are an important source of violations of absolute purchasing power parity. Using highly disaggregated export data, we document systematic international price discrimination: at the US dock, low-income countries pay lower prices....

"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...

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...

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...
