Importers, Exporters, and Exchange Rate Disconnect

Abstract

Large exporters are simultaneously large importers. We show that this pattern is key to understanding low aggregate exchange rate pass-through as well as the variation in pass-through across exporters. We develop a theoretical framework with variable markups and imported inputs, which predicts that firms with high import shares and high market shares have low exchange rate pass-through. We test and quantify the theoretical mechanism using Belgian firm-product-level data on imports and exports. Small nonimporting firms have nearly complete pass-through, while large import-intensive exporters have pass-through around 50 percent, with the marginal cost and markup channels contributing roughly equally.
