Il lavoro riassume le principali implicazioni dell’ipotesi del ciclo vitale per quanto riguarda il risparmio individuale e aggregato, la politica fiscale e la previdenza sociale, soffermandosi sui contributi più importanti di Modigliani su questi temi. Anche se non è facile conciliare alcuni risultati empirici recenti con l’ipotesi del ciclo vitale, soprattutto gli aspetti di inerzia, miopia e comportamento irrazionale documentati nella letteratura comportamentale, gli studi di Modigliani rappresentano ancora oggi la base di riferimento principale per studiare le decisioni di risparmio individuali e per operare scelte di politica economica.
The paper summarizes the main implications of the life cycle hypothesis regarding the individual and aggregate saving, fiscal policy and social security, focusing on the most important contributions of Modigliani on these issues. Although it is not easy to reconcile some recent empirical results with the hypothesis of the life cycle, especially the aspects of inertia, myopia and irrational behavior documented in the literature behavioral, the studies of Modigliani still represent the basis of reference for the study of individual savings decisions and to make policy choices.
