The economic impact of the Regional Policy of the European Union is still controversial. This paper exploits administrative boundaries as spatial discontinuity to estimate the causal effect of this policy on the Italian Objective 1 regions’ employment. The analysis, developed both in a border strategy framework (municipalities contiguous to the policy‐change boundary) and with more traditional RDD models balanced by spatial forcing variables (centroids’ distance and coordinates), shows that the EU Regional Policy produced a positive impact on employment levels, without any displacement of economic activities away from nontreated regions and a concentration of the impact in key economic sectors.
