The literature contains numerous studies examining the efficacy of cohesion policy. However, these analyses consistently overlook the outermost regions (ORs) of the European Union. Nevertheless, considering the unique challenges faced by these regions such as their extremely remote locations, poverty, and reliance on foreign trade, it is crucial to ascertain whether they have managed to narrow the development gap in comparison to other European regions. Employing a cross-sectional study and panel data, we investigate the presence of β-convergence among 242 regions from 2003 to 2021. Our findings indicate that despite receiving subsidies from the European Structural and Investment Funds for several decades, the outermost regions still lag behind the rest of Europe in terms of development.
