The objective of this paper is to show the influence of the primary inputs prices on the production prices in the Catalan Economy. The methodology we use is the input-output framework, which has permitted us to reflect the changes in the prices of domestic processing sectors under changes in their input costs. Our results demonstrate that production prices react with higher intensity when there is a change in the import costs, in comparison with a change in the domestic costs. This evidence allows us to conclude that the price control inside the economy may be very limited when the increased cost is caused by the foreign sector.
