The impact of European Cohesion Policy in urban and rural regions. Regional Studies. This paper presents an evaluation exercise on the impact of European Cohesion Policy on the economic performance of the most disadvantaged European areas (Objective 1 regions) for the programming period 2000–06. By performing the analysis at NUTS-3 rather than NUTS-2 level to exploit the exogeneity of the treatment status in the context of a regression discontinuity design (RDD), the analysis shows that European Cohesion funds have positively contributed to generating economic growth in lagging areas. However, their effect is mainly driven by the successful performance of rural areas close to the main urban agglomerates. Favourable geography and the progressive suburbanization of the rural landscape created new opportunities for rural areas close to cities, thus boosting the effect of the policy.
