What drives export quality? Using firm-level data from Portugal on exports by product and destination market, we find that free-on-board unit values increase systematically with distance, and tend to be higher in shipments to richer nations. These relationships reflect not only the selection of firms across markets, but also the within-firm selection of product varieties across destinations. Furthermore, they prevail irrespective of the size of the exporter and the value of the export flow.

This paper examines the extent to which the destination of exports matters for the input prices paid by firms, using detailed customs and firm-product-level data from Portugal. We use exchange-rate movements as a source of variation in export destinations and find that exporting to richer countries leads firms to charge more for outputs and pay higher prices for inputs, other things equal. The results are supportive of the hypothesis that an exogenous increase in average destination income leads firms to raise the average quality of goods they produce and to purchase higher-quality inputs.

This paper examines the relationship between the destination of exports and the input prices paid by firms, using detailed customs and firm-product-level data from Portugal. Both ordinary least squares regressions and an instrumental-variable strategy using exchange-rate movements (interacted with indicators for initial exports) as a source of variation in destinations indicate that exporting to richer countries leads firms to pay higher prices for inputs, other things equal. The results are supportive of what we call the income-based quality-choice channel: selling to richer destinations leads firms to raise the average quality of goods they produce and to purchase higher-quality inputs.
