There is abundant evidence that immigrants' networks are associated with larger trade flows between countries of origin and the country (or province) where they settle. The causality of such relation and its magnitude, however, have not been proven beyond reasonable doubt. We use the simple...

Using data for all exporters, we show that it is a small group of firms that dominate exports in Spain. For example, in 2015 the top 200 firms were responsible for half of Spanish exports. This concentration has not changed substantially over the 1997-2015 period. The dominance of a few firms, a...

To estimate correctly the effect of variable trade costs on firms' exports, the gravity equation should control for the number of firms that participate in foreign markets. Due to the absence of these data, previous studies control for this omitted variable using econometric strategies that may...

We investigate the effects of an immigration shock, which is still on course, in the productive structure of Spanish regions in a Heckscher-Ohlin framework. Immigration alters relative factor endowment composition across Spanish regions. The persistence of rigidities in the regional labour...
