13In order to get an idea of whether significant differences regarding inter-regional migration patterns exist among European Member States, we run additional regressions for selected EU Member States. The results are reported in Table A.3 in the appendix and reveal important differences across EU countries in the factors that determine migration patterns. While in some countries pecuniary migration incentives seem to exert some influence on inter-regional net migration, this is not the case in all of the others. Unemployment and youth generally play a more important role in almost all Member States analysed.
