The retirement decisions of spouses may be interdependent for various reasons: similarity of tastes, joint assets, sharing rules for income and housework, or complementarity of leisure. Because of data limitations, only a few empirical studies exist on this topic. From a policy point of view...

Private pension provision faces the challenging task of providing stable income streams during retirement. The challenge has increased markedly in the last decades due to volatile financial markets, falling interest rates and the withdrawal of employers and external insurers as risk bearers of...

We investigate intergenerational risk sharing in two-pillar pension systems with a pay-as-you-go pillar and a funded pillar. We consider shocks in productivity, depreciation of capital and inflation. The funded pension pillar can be either defined contribution or defined benefit, with benefits...

In 1998, the Swiss voters approved of an increase in female retirement age from 62 to 64. The referendum, being on a single issue only, offers a unique opportunity to explore the political feasibility of pension reforms and to apply theoretical models of life-cycle decision making. Estimates...

Starting from a simple, descriptive model of individual income, an explicit link between the age composition of a population and the personal distribution of incomes is established. Demographic effects on income inequality are derived. Next, a pay-as-you-go financed state pension system is...

The paper reviews recent research on the impact of an aging population on the distribution of income. After briefly discussing the demographic conditions responsible for population aging, a short account is given of demographic trends in the industrialized world. In order to disentangle the many...

In this Paper, we study the role of subsidies to fertility in ensuring the political viability of unfunded social security (SS). In our model, agents are heterogeneous in age and income. Young generations confront promises made previously by older generations, and in turn choose current levels...

This paper uses stochastic simulations on calibrated models to assess the optimal degree of reliance on funded 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...

When entering retirement most people face the decision whether they would like their defined contribution account balance paid as a lump sum or to annuitize the amount. The fact that people tend to choose the lump sum even if economic reasons suggest not to is called the annuity puzzle. In a...

The European ageing process will lead to a dramatic rise in dependency ratios over the next decades. At the same time labour mobility will increase as a result of greater European economic integration. We analyse the implications of migration and ageing for European social security systems. With...
