The structure of the Polish pension insurance system, despite many reforms carried out in recent years, is still mainly based on the pay-as-you-go (repartition) pillar. To make it work properly, a constant inflow of participants who will pay contributions, thanks to which it will be possible to...

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...

The sustainability of a defined benefit pay-as-you-go (DBPAYG) pension system is investigated in the context of an overlapping-generations model of endogenous fertility with heterogeneous agents. The model places particular emphasis on the time costs of child rearing. It illustrates the...

In this paper, we propose a novel index for measuring intra-generational redistribution in pay-as-you-go pension schemes. Our index solely requires information on contributions and pension benefits of retirees, enabling us to measure intra-generational redistribution isolated from possible...

Notional Defined Contribution (NDC) pension schemes are defined contribution plans which are pay-as-you-go financed. From a design viewpoint, the countries where NDCs have been implemented cannot guarantee sustainability due to the choice of notional return paid to the contributions and the...

This paper studies the effect of demographic change on national saving, global interest rates, and international capital flows, focusing on the role of the public pension system. We develop a small open economy overlapping generations model to illustrate the channels through which demographic...
