Recent years have seen a surge of interest among industrial organization economists in using data on international trade flows as windows into competitiveness. For countries that are at least mid-sized (e.g., Spain), interregional trade tends to be as large as or significantly larger than...

Studies of competitiveness tend to focus on a local economy's global interactions, particularly its international trade. But for countries that are at least mid-sized (such as Spain), interregional trade tends to be as large as or significantly larger than international trade. The case of...

Previous studies have shown that, not only countries, but also regions have a preference to trade within their administrative borders. Using unique trade flows data, we also find a large home bias in Spanish intranational trade. However, we show that this home bias disappears once we take into...

The existence of a large border effect is considered as one of the main puzzles of international macroeconomics. We show that the border effect is, to a large extent, an artefact of geographic concentration. In order to do so we combine international flows with intranational flows data...

We introduce a Bayesian hierarchical regression model that extends the traditional least-squares regression model used to estimate gravity or spatial interaction relations involving origin-destination flows. Spatial interaction models attempt to explain variation in flows from n origin regions...

In this note we introduce the 1995 Spanish Interregional Input-Output Model, which was estimated using a wide set of One-region input-output tables and interregional trade matrices, estimated for each sector using interregional transport flows. Based on this framework, and by means of the...

After the seminal paper by McCallum, various authors have estimated the effect of regional and national borders on trade. This paper digs deeper into the matter, estimating how the internal and external border effect is affected by the non-linear relation between trade and distance at different...

En España no existe información oficial sobre el comercio interregional de bienes. En el marco del proyecto C-intereg se ha estimado la primera base de datos de comercio con detalle provincial, tomando como punto de partida la información disponible sobre transporte de mercancías junto con...
