The means-testing of age pension programs allows governments to control the receipt of pension benefits (extensive margin) and the benefit level (intensive margin). We investigate how the presence of the extensive margin influences the trade-off between protecting the poorer elderly and the...

This paper assesses the effect of social security privatization on the government budget, economic efficiency, national saving, and the distribution of resources across generations. It is shown that the benefits of privatization most often touted by privatization advocates can be achieved by...

How well did the Social Security system do last year? According to the most recent annual report prepared by system's Board of Trustees, the Social Security trust funds showed a $165.4 billion net increase in assets in 2002 and reported accumulated reserves of nearly $1.4 trillion by year end....

In this paper we consider an overlapping generations model with endogenous fertility and two-sided altruism and show the limitations of applying commonly used open loop Nash equilibrium in characterizing equilibrium transfers from parents to children in the form of bequest and transfers from...

We trace the impact of pay-as-you-go (PAYG) social security taxes on demographic and economic trends through an endogenous-growth model where human capital is the engine of growth, family choices affect its formation in children, and family formation itself is a choice variable. We show that...

We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimality. Our characterization also subsumes equilibria with a PAYG social security system. In a competitive equilibrium...

We model the optimal reaction of a public PAYG pension system to demographic shocks. We compare the ex-ante first best and second best solution of a Ramsey planner with full commitment to the outcome under simple third best rules that mimic the pension systems observed in the real world. The...
