This paper studies the effect of exchange rate shocks on export behavior of multi-product firms. We provide a theoretical framework illustrating how firms adjust their prices, quantities, product scope, and sales distribution across products in the event of exchange rate fluctuations. In response to a real exchange rate depreciation, firms increase markups for all products, but markup increases decline with firm-product-specific marginal costs of production. We find robust evidence for our theoretical predictions using Brazilian customs data containing destination-specific and product-specific export sales and quantities. The sample period covers the years 1997–2006, during which Brazil experienced a series of drastic currency fluctuations. (JEL F14, F31, F33, O19, O24)
