Analysis of interregional labor migration in Spain using gross flows

This paper studies the economic determinants, from an aggregate perspective, of Spanish interregional labor force flows. Its main characteristics are that it is based on a matching model of the labor market applied to migration, and that uses gross flows instead of net ones as other studies do.
