In this paper we contribute to the empirical literature on the size of network effects of public infrastructures. A novel approach is introduced to this purpose. Moving from estimates of the common dynamics shared by the regional public capital stock series, identification of co‐ordinated policy shocks is obtained within a properly specified structural vector error correction model. Our empirical findings confirm previous evidence that transport infrastructures exert positive effects in the long run. At the same time, we find evidence that this influence is mostly attributable to the impact of co‐ordinated public policy shocks, as predicted by the literature on network externalities. Resumen En este artículo contribuimos a la literatura empírica sobre el tamaño de los efectos de red de infraestructuras públicas. Para este propósito se presenta un enfoque novedoso. A partir de estimaciones de las dinámicas comunes compartidas por series de reservas de capital público regional, la identificación de perturbaciones políticas se realiza dentro de un modelo de corrección del error vectorial estructural debidamente especificado. Nuestros descubrimientos empíricos confirman indicios anteriores de que las infraestructuras de transporte ejercen efectos positivos a largo plazo. A la vez, hallamos pruebas de que esta influencia es atribuible principalmente al impacto de perturbaciones en las políticas públicas coordinadas, tal y como predice la literatura sobre externalidades de red.
