Pensions may be provided for in a modern society by a mix of several methods, namely by voluntary individual savings, mandatory fully-funded occupational pension systems, mandatory social security financed by pay-as-you-go, and old-fashioned hoarding in cash. Here, we call the specific mixture...

This paper uses stochastic simulations on calibrated models to assess the optimal degree of reliance on fun ded pensions and on a particular type of unfunded (PAYG) pension. Surprisingly little is known about the optimal split between funded and unfunded systems when there are sources of...

The Croatian system of old-age provision comprises a traditional public pay-as-you-go scheme and a mandatory funded scheme ("second pillar") that will provide increasing amounts of supplementary pensions to those entering retirement in the future. Due to the continuing economic crisis, the...

We analyze the political stability of capital funded social security. In particular, using a stylized theoretical framework we study the mechanisms behind governments capturing pension assets in order to lower current taxes. This is followed by an analysis of the analogous mechanisms in a...

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...

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...

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...

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 some results from a model built in order to study the linked impacts of demography and economy on theFrench pension scheme. The demo-economic model which is used is a neo-cambridgian model with two types of agents in aclosed economy. Since it includes a very thin description...

Pension benefit rules depend on individual history far more than taxes do, and age plays a much larger role in pension determination than in tax determination. Apart from some simulation studies, theoretical studies of optimal tax design typically contain neither a mandatory pension system nor...
