“…The majority of studies draw on samples of EU NUTS2 regions and employ cross‐sectional or panel data (Beugelsdijk & Eijffinger, ; Cappelen, Castellacci, Fagerberg, & Verspagen, ; Ederveen, de Groot, & Nahuis, ; Ederveen, Gorter, de Mooji, & Nahuis, ; Esposti & Bussoletti, ; Puigcerver‐Peñalver, ; Rodríguez‐Pose & Fratesi, ). More recent works have attempted to address endogeneity issues by using instrumental variable models in combination with spatial econometric techniques (Bouayad‐Agha, Turpinn, & Védrine, ; Dall'erba & Le Gallo, ; Mohl & Hagen, ; Ramajo, Marquez, Hewings, & Salinas, ). In spite of the large number of studies produced, this literature has not reached a consensus on whether Structural Fund spending is beneficial (Bahr, ; Cappelen et al., ; Becker, Egger, & von Ehrlich, ; Esposti & Bussoletti, ), beneficial under certain conditions (Becker et al., ; Bouayad‐Agha et al., ; Crescenzi & Giua, ; Mohl & Hagen, ; Rodríguez‐Pose & Fratesi, ; Rodriguez‐Pose & Garcilazo, ; ), insignificant (Dall'erba & Le Gallo, ; Garcia‐Milá & McGuire, ) or even detrimental and unjustified (Boldrin & Canova, ; Dall'erba, Guillain, & Le Gallo, ).…”
