Applying difference-in-difference estimation on individual-level data, our findings suggest that the Öresund Bridge led to a significant increase in the number of patents per individual in the Malmö region as compared to the two other major regions in Sweden, Gothenburg and Stockholm. We show that a key mechanism is the attraction of highly qualified workers to the Malmö region following the construction of the bridge.enagglomeration effectsbridgecross-border regionsInnovationinventorÖresundpatentstransportation infrastructure303600journal article
