The Extensive Margin of Exporting Products: A Firm-level Analysis

We examine multi-product exporters and use firm-product-destination data to quantify export entry barriers. Our general-equilibrium model of multi-product firms generalizes earlier models. To match main facts about multi-product exporters, we estimate our model with rich demand and access cost shocks for Brazilian firms. The estimates document that additional products farther from a firm’s core competency incur higher unit costs, but face lower market access costs.
