In the early 1950s Modigliani, with Brumberg and Ando, formulated the life-cycletheory of consumption and savings that enjoyed a huge and undisputed success. But, since the early 1980s, the life-cycle theory has increasingly come under attack. One reason is the existence of an important...

The maximum amount of earnings in a calendar year that can be taxed by Social Security in the U.S. is currently capped at $106,800. In this paper, I use a general-equilibrium overlapping-generations model to examine if removing this cap can solve Social Security's budgetary problems. I find that...

This paper incorporates two features of housing in a life-cycle analysis of social security: housing as a durable good and housing market frictions. We find that with housing as a durable good unfunded social security substantially crowds out housing consumption throughout the life cycle. By...

This paper incorporates two features of housing in a life-cycle analysis of social security: housing as a durable good and housing market frictions. We find that both housing quantities and homeownership rates respond strongly to eliminating social security. Accordingly, the aggregate impacts of...

We investigate welfare and aggregate implications of a pay as you go (PAYG) social security system in a dynastic framework in which agents have self-control problems. The presence of these two additional factors at the same time affects individuals’ intertemporal decision problems in two...

We investigate welfare and aggregate implications of a pay-as-you-go (PAYG) social security system in a dynastic framework in which individuals have self-control problems. The presence of self-control problems induces individuals to save less because of their urge for temptation towards current...

This paper analyzes the dynamic politico-economic equilibrium of a model where repeated voting on social security and the evolution of household characteristics in general equilibrium are mutually affected over time. In particular, we incorporate within-cohort heterogeneity in a two-period...

In this Paper, we study the role of subsidies to fertility in ensuring the political viability of unfunded social security (SS). In our model, agents are heterogeneous in age and income. Young generations confront promises made previously by older generations, and in turn choose current levels...
