Equilibrium and Italian fiscal sociology: a reflection on the Pareto-Griziotti and Pareto-Sensini letters on fiscal theory

This paper reflects on the influence of Vilfredo Pareto's letters on Ricardian equivalence and fiscal theory to Benvenuto Griziotti and Guido Sensini. The letters are important for emphasizing the need for fiscal studies to consider equilibrium, particularly social equilibrium, at a time when Italian fiscal sociology was in its formative stage. Griziotti came to accept fiscal sociology, albeit in an eclectic form that focused directly oil political and legislative matters rather than social equilibrium. In contrast, Sensini progressively developed a framework for fiscal theory that focused primarily on the fundamental relationship between fiscal phenomena and social equilibrium.
