This dissertation consists of three chapters. In Chapter 1, I present a literature review on the main theoretical contributions modeling social security design assuming non-standard household preferences. We focus on three particular approaches: time inconsistent preferences, temptation preferences and myopia. Chapter 2 investigates the political incentives for the design of social security policy in competitive democracies with both far-sighted and myopic households in a probabilistic voting setting. In particular, the analysis focuses on the trade-off between the size and the redistribution degree of the equilibrium social security policy. Chapter 3 introduces myopic saving behavior in a two-country normative model of social security, in which non-cooperative and cooperative pension policies are compared. Moreover, this chapter analyzes the effects of cooperation to world capital accumulation with the presence of myopic agents.
Questa tesi si compone di tre capitoli. Nel primo capitolo, si presenta una rassegna della letteratura sui principali contributi teorici di modellazione per la progettazione della sicurezza sociale, assumendo gli individui come non-standard preferences. Ci concentriamo su tre approcci particolari: time inconsistent preferences, temptation preferences e myopia. Il secondo capitolo studia gli incentivi politici per la progettazione della politica di sicurezza sociale nelle democrazie competitive con le famiglie lungimiranti e miopi in un ambiente di probabilistic voting. In particolare, l'analisi si concentra sul trade-off tra le dimensioni e il grado di redistribuzione del sistema pensionistico. Il terzo capitolo introduce il comportamento miope di risparmio in un modello pensionistico a due paesi, in cui vengono confrontate le politiche pensionistiche non-cooperative e cooperative. Inoltre, questo capitolo analizza gli effetti di cooperazione per l'accumulo di capitale mondiale con la presenza di agenti miopi.

Abstract
This dissertation consists of three chapters. In Chapter 1, I present a literature review on the main theoretical contributions modeling social security design assuming non-standard household preferences. We focus on three particular approaches: time inconsistent preferences, temptation preferences and myopia. Chapter 2 investigates the political incentives for the design of social security policy in competitive democracies with both far-sighted and myopic households in a probabilistic voting setting. In particular, the analysis focuses on the trade-off between the size and the redistribution degree of the equilibrium social security policy. Chapter 3 introduces myopic saving behavior in a two-country normative model of social security, in which non-cooperative and cooperative pension policies are compared. Moreover, this chapter analyzes the effects of cooperation to world capital accumulation with the presence of myopic agents.File | Dimensione | Formato | |
