In earlier literature, the suggested Pareto improvements in pay-as-you-go (PAYG) systems have relied on the presence of externalities or the possibility of intragenerational redistribution. We show that neither assumption is necessary in an economy with intergenerational trade in a fixed factor...

Almost all papers on the feasibility of a Pareto improving transition path from a Pay-as-you-go to a fully funded system employ lump sum or wage taxes for financing the compensating transfers. This paper focuses on this issue by using consumption or proportional income taxes and applying a...

This paper analyzes the transition from a pay-as-you-go to a fully funded pension system within the framework of endogenous growth in the presence of uncertainty. Gyárfás and Marquardt (2001) prove the possibility of a Pareto improving conversion in a certain world. Two distinct kinds of...

This paper contains nine different essays on Social Security reform and multi-pillar pension plans. The nine topics are: 1. Transition costs2. Progressive indexation3. Government guarantees on private accounts4. Life cycle investing5. Impact of add-on accounts on Social Security solvency6....

This paper explores the introduction of collective risk-sharing elements in defined contribution pension contracts. We consider status-contingent, age-contingent and asset contingent risk-sharing arrangements. All arrangements raise aggregate welfare, as measured by equivalent variations. While...

Pensions may be provided for in a modern society by several methods, viz., voluntary individual savings, mandatory fully funded occupational pension systems, and mandatory social security financed by pay-as-you-go. The specific mixture of the three systems we will call the pension composition....

In this paper I use a multi-period OLG model to study how a demographic shock is distributed among different generations. In particular, I investigate whether a funded pension system allows for a smoother adjustment than an unfunded system. The results suggest that the answer to this question...
