Abstract
The paper aims to contribute to the debate on the transformative power of the PNRR on the Italian regional system by analyzing the transformative potential of federal spending power in the context of a selection of European federal systems. The analysis focuses on Germany and Spain. Since the two federal systems largely follow the paradigm of ‘administrative federalism’ and are characterized by a high degree of fiscal centralization, the exercise of the federal spending power deserves particular attention because of its impact on the autonomy of the Länder and Autonomous Communities.
