Exporting costs and multi‐product shipments*

In this paper, employing transaction level data for Russian imports, we explore the role of multi-product shipments in explaining shipping patterns across countries. our data, an average shipment includes five different products. We document that firms from higher income countries on include a larger number products into single and have per period with lower quantity value. then propose mechanism reconciles both facts. Specifically, allow to split fixed costs many and, therefore, reduce total costs. As result, tend shipment. Finally, construct simple partial equilibrium model enables us quantify potential increases trade volumes welfare created by option. This article is protected copyright. All rights reserved.
