Beschreibung:
We analyze the impact of an inflow of foreign workers on positional wage mobility in a small open economy like Switzerland. We exploit the quasi-natural experiment constituted by the entry into force of the Agreement on the Free Movement of Persons between Switzerland and the EU on 1st June 2002. We compute conditional average treatment effects with machine learning methods, and we find evidence of relevant heterogeneity in the impact of this policy on wage mobility
