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...

In recent decades, many states have reduced future retirement benefits for newly hired teachers. We estimate that in 2020 the average initial monthly retirement benefit, for teachers retiring with 30 years of service, is 11.2 percent lower than that of teachers retiring in the same plan with the...

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...

This paper studies the impact of recent changes in second pension pillars of three Central and Eastern European Countries on the deficit and implicit debt of their full pension systems. The paper seeks to answer the following questions: what is the impact on the sustainability of Poland's...

The paper discusses the options for a reform of the German pension system using a model developed at CES for the German Council of economic advisors to the Federal Ministry of Economics and Research. It is argued that the German pay-as-you-go-system is efficient in a present value sense but will...

Twenty years ago, the adjustment to monthly Social Security benefits for early or delayed claiming was, on average, roughly actuarially fair, although some subsets of individuals could gain from delay. Since then, delaying claiming has become much more attractive thanks to three factors: a more...

A pay-as-you-go (paygo) pension program may provide intergenerational pooling of risks to individuals' labor and capital income over the life cycle. By means of a model that provides illuminating closed form solutions, we demonstrate that the magnitude of the optimal paygo program and the nature...

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 paper analyses the impact of demographic developments on the German pension system until the year 2060. The projections are simulated for a range of assumptions on the latest demographic trends and on the labour market and comprise the latest pension legislation. As a central innovation we...

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...
