Traditionally, the effectiveness of European Cohesion Policy has been evaluated in terms of GDP growth rate. In this paper, we consider the effect of the regional policy in terms of its impacts on two specific fields of intervention, namely 'research, technological development and innovation', and 'transport infrastructure'. Our econometric approach involves the use of a non-parametric regression discontinuity design technique to a uniquely-disaggregated Cohesion Policy dataset broken down according to the specific objectives of each stream of funding. The analysis considers different time intervals and sub-samples. Our results demonstrate a positive impact of Cohesion Policy interventions in these two specific fields of intervention.
