We explore the benefits of intergenerational risk-sharing through both private funded pensions and via the public debt. We use a multi-period overlapping generations model with a PAYG pension pillar, a funded pension pillar and a government. Shocks are smoothed via the public debt and variations...

The recent financial crisis and historical record suggest important lessons about the design of national pension systems. First, wide fluctuation in asset returns makes it hard for well-informed savers to select a saving rate or a sensible investment strategy for DC pensions. Workers who follow...

Demographic trends in most developed economies are characterized by rising longevity and decreasing birthrates. These trends endanger the sustainability of the current public pension systems. Therefore social security reform proposals are on the agenda in many countries. This paper demonstrates...

Fertility has long been declining in industrialised countries and the existence of public pension systems is considered as one of the causes. This paper is the first to provide detailed evidence based on historical data on the mechanism by which a public pension system depresses fertility. Our...

We investigate numerically how indexation of funded pensions for inflation can be differentiated across the various groups of fund participants. The pension arrangement is modelled after the Dutch situation. While the aggregate welfare consequences are small, group-specific consequences are more...

This paper provides a unified treatment of externalities associated with fertility and human capital accumulation as they relate to pension systems. It considers as overlapping generations model in which every generation consists of high earners and low earners with the proportion of types being...

Conventional pension systems suffer from a design defect which makes them financially unsustainable, and a source of inefficiency for the economy as a whole. The paper outlines a second-best policy which includes a public pension system made up of two parallel schemes, a Bismarckian one allowing...

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 aging of the populations in the OECD countries has prompted various calls for reforming the existing pay-as-you-go (PAYG) pension systems. Currently, there is renewed discussion in the United States about partial privatization where a fraction of the social security payroll tax would be...

This paper discusses mandatory participation in Dutch occupational pension schemes. While mandatory participation is a historical feature of most second-pillar pension arrangements, some recent developments may affect the case for mandatory participation. The main ones are the revision of the...
