GRANTPA: The Granular Trade and Production Activities
The Granular Trade and Production Activities (GRANTPA) database covers international and domestic trade flows for 3,124 products and 247 countries over the period 1995-2019 for a subset of 35 European economies. The original data sources that we employ are Eurostat's Comext and Prodcom databases.
The GRANTPA is the first dataset that offers consistently constructed international and domestic trade at such a detailed level of disaggregation.
The data are tested with a gravity application, which delivers a large set of product-level “home bias” estimates, which cannot be obtained without domestic trade flows. The average estimates on the standard gravity variables in our model (e.g., distance) are comparable to those from the related literature. However, our disaggregated estimates are very heterogeneous across products, thus highlighting the importance of our new database.
