Agglomeration and trade performance–evidence from the Norwegian salmon aquaculture industry

Abstract

Geographical concentration of industries tends to be important for firms that depend on innovation and are intensive in the use of specialized technology and labor. In this paper, we investigate the interaction between agglomeration and trade performance in the Norwegian aquaculture industry. We include a variable for regional clustering in a standard gravity model and estimate its impact on different margins of trade. When controlling for destination country, we find that firms that operate in clusters obtain higher export prices and ship more frequently and in smaller bulks. For a highly perishable product like fresh salmon, this may suggest that firms in clusters are served by more efficient supply chains bringing the product to market with timely and efficient logistics.
